[0002] In daily office work, it is often necessary to merge multiple documents of formats such as Word (.doc / .docx), Excel (.xls / .xlsx) and PDF (.pdf) into a single document. However, the existing document merging solutions generally have a serious problem of format and header and footer loss, that is, when processing multiple Word documents, the traditional copy and paste or most document merging tools will merge all the contents into a continuous "section", which causes the header and footer of the subsequent document to be covered by the previous section, or the header and footer of the entire document to be unified, and the independent layout of each source document cannot be preserved. Although the existing technology involves document merging, the header and footer processing thereof relies on "inheritance" to achieve unification, which destroys the independence of the header and footer of the source document.

DETAILED DESCRIPTION

[0018] The scheme of the embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0019] In the following description, specific details are set forth in order to provide a thorough understanding of the present application. However, persons having ordinary skill in the art will appreciate that the present application can be practiced without the specific details.

[0020] The term "and / or" herein merely describes an association relationship of associated objects, and means that there can be three relationships, for example, A and / or B can mean that there are three cases of A alone, A and B together, and B alone. In addition, the character " / " herein generally means that the front and rear associated objects are in an "or" relationship. In addition, "multiple" herein means two or more than two. In addition, the term "at least one" herein means any one of multiple or any combination of at least two of multiple, for example, including at least one of A, B, and C can mean including any one or more elements selected from the set consisting of A, B, and C.

[0021] As described in the background, the existing document merging solutions generally have a serious loss of format and header and footer, and therefore there is an urgent need for a document merging solution that can intelligently, automatically, and losslessly batch merge multiple format documents and ensure that the format and header and footer integrity of each document is preserved.

[0022] To solve the above problems, the present application proposes a new document merging scheme. In the scheme of the present application, a verification and repair module is integrated in the document merging system and is in communication connection with the document merging module. The verification and repair module is used to verify and repair the header and footer of the output document, so that the sectioning, header and footer of all documents in the output document remain the original format before merging. In this way, multiple format documents can be intelligently, automatically and losslessly merged in batches, and the format and header and footer integrity of each document are preserved.

[0023] The specific embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0024] According to one embodiment of the present application, as shown in Figure 1 and 2 , the present application proposes a document merging system for merging multiple documents to be merged of different or same formats. The system of the present application includes an interaction and configuration module, a document analysis and routing module, a document merging module, and a verification and repair module. The interaction and configuration module includes a document operation graphical interface configured to allow a user to add and sort the documents to be merged, and set the output path, output format and merging options of the output document. The document analysis and routing module is in communication connection with the interaction and configuration module and the document format conversion module, and is configured to identify the document extension of the multiple documents to be merged, and based on the document extension of the multiple documents to be merged and the output path, output format and merging options of the output document, dynamically route the multiple documents to be merged to the document format conversion module. The document merging module is in communication connection with the document analysis and routing module and the document format conversion module, and is configured to merge the multiple documents to be merged to obtain the output document. The verification and repair module is in communication connection with the document merging module, and is configured to verify and repair the header and footer of the output document, so that the sectioning, header and footer of all documents in the output document remain the original format before merging.

[0025] The inventor has also found through research that some existing document merging schemes have low or no cross-format merging support: most tools only support the merging of single format documents. For the merging needs of mixed Word, Excel and PDF documents, although the existing technology proposes the idea of converting different formats to a temporary target format before merging, its focus is on preserving directories, links and other "additional information", and does not solve the problem of maintaining the original format layout and header and footer when merging different format documents into Word or PDF. In actual tests, the failure rate of mixed merging is extremely high.

[0026] Therefore, in the present embodiment, as shown in Figure 1 and 3As shown, the system of the present application further comprises: a document format conversion module: wherein the document format conversion module is in communication connection with the document analysis and routing module, the document merging module, and is configured to convert the document format of one or more to-be-merged documents and transmit it to the document merging module for merging processing when the to-be-merged documents are not in the set output format.

[0027] As can be known from the above description, by introducing the document format conversion module, the embodiment effectively solves the problems of layout distortion, header and footer disorder, and high failure rate caused by format heterogeneity in the merging process of mixed format documents (such as Word, Excel, PDF) in the prior art; the module can uniformly and accurately convert the documents in non-target format to the set output format (such as Word or PDF or Excel) before merging, and focus on preserving the original layout structure and key format elements such as header and footer during the conversion process, thereby significantly improving the success rate and output quality of cross-format document merging, and realizing high-fidelity and high-compatibility one-stop mixed document merging.

[0028] In the embodiment, still referring to Figure 1 As shown, the document merging module of the present application comprises: a PDF document merger in communication connection with the document analysis and routing module, the verification and repair module, and the document format conversion module, and is configured to perform merging processing on the to-be-merged documents with the document extension name.pdf transmitted by the document analysis and routing module and / or the document format conversion module; a Word document merger in communication connection with the document analysis and routing module, the verification and repair module, and the document format conversion module, and is configured to perform merging processing on the to-be-merged documents with the document extension name.docx or.doc transmitted by the document analysis and routing module and / or the document format conversion module; and an Excel document merger in communication connection with the document analysis and routing module, the verification and repair module, and the document format conversion module, and is configured to perform merging processing on the to-be-merged documents with the document extension name.xlsx transmitted by the document analysis and routing module and / or the document format conversion module.

[0029] As can be known from the above description, by setting the dedicated PDF, Word, and Excel document mergers and working cooperatively with the document analysis and routing module, the format conversion module, and the verification and repair module, the embodiment not only can realize high-fidelity merging of 100% preservation of the original independent format, header, footer, and section settings for documents of the same format (such as multiple Word files), but also can efficiently handle mixed scenarios of heterogeneous formats such as Word, Excel, and PDF, and uniformly output them as a single PDF file, while ensuring the lossless restoration of key format elements such as layout, header, and footer of each source document in the final PDF, thereby significantly improving the compatibility, stability, and output quality of cross-format document merging.

[0030] In the embodiment, asFigure 4 As shown in the PDF document merger of the present application is configured to perform the document merging operation according to the following steps S1-S2: S1, after receiving each to-be-merged document with the document extension name.pdf, automatically inserting a "next page section marker" at the end of the to-be-merged document; S2, merging the to-be-merged documents in the order of reception.

[0031] In this embodiment, as shown in the Word document merger of the present application is configured to perform the document merging operation according to the following steps T1-T3: T1, after receiving each to-be-merged document with the document extension name.docx or.doc, automatically inserting a "next page section marker" at the end of the to-be-merged document; T2, embedding each to-be-merged document into the output document, and setting the document connection property of the to-be-merged document embedded in the output document to "false"; T3, locating each section marker in the output document, and setting the previous section connection property of the header and footer of the to-be-merged document corresponding to the section marker to "false". Figure 5 In this embodiment, as shown in the Excel document merger of the present application is configured to perform the document merging operation according to the following steps P1-P2: P1, after receiving each to-be-merged document with the document extension name.xlsx, automatically inserting a "next page section marker" at the end of the to-be-merged document; P2, merging the to-be-merged documents in the order of reception.

[0032] Figure 6 As can be seen from the above description, the present embodiment effectively realizes the clear isolation of the format boundaries of the multi-source documents in the merging process by introducing a unified "next page section marker" insertion mechanism in the PDF, Word and Excel document mergers, and combining the embedded property control and the header and footer "LinkToPrevious" disconnection operation specific to the Word document. Not only does it ensure the independent section structure of each source document and the header and footer content is not disturbed or covered by the subsequent document, but it also avoids the format pollution problem caused by the default link to the previous section. Especially in the Word merging, by explicitly setting the connection property of the embedded document to "false" and disconnecting the association between the header and footer and the previous section, the format integrity of each source document is completely guaranteed, thereby significantly improving the accuracy, stability and professionalism of the same format and cross-format merging results.

[0033] The inventor has also found through research that the existing document merging solutions have low automation and poor stability. Solutions that rely on the Microsoft Office COM (Component Object Model) interface frequently pop up warning windows during execution, and there is a memory leakage problem caused by the failure to completely release the process, which cannot achieve stable and silent background batch processing.

[0034] The inventor has also found through research that the existing document merging solutions have low automation and poor stability. Solutions that rely on the Microsoft Office COM (Component Object Model) interface frequently pop up warning windows during execution, and there is a memory leakage problem caused by the failure to completely release the process, which cannot achieve stable and silent background batch processing. ​

[0035] Thus, in the present embodiment, still referring to Figure 1 As shown, the document merging system of the present application further comprises: a global singleton manager, which is in communication connection with the Word document merger, the Excel document merger, and the document format conversion module, and is configured to manage COM objects of the to-be-merged documents with the document extension.docx or.doc and the to-be-merged documents with the document extension.xlsx in the singleton mode, wherein only one COM instance is created and reused throughout the entire document merging process, and the reuse rate of the COM objects is increased by more than 300%, greatly reducing resource consumption and startup time; a double-silence setter, which is in communication connection with the Word document merger, the Excel document merger, and the document format conversion module, and is configured to set Application.Visible = "False" and Application.DisplayAlerts = "False" at the same time when the COM objects are obtained, so as to eliminate user interface interference and pop-up warnings during the merging operation; and a resource release controller, which is in communication connection with the Word document merger, the Excel document merger, and the document format conversion module, and is configured with an atexit function and an application exit event listener, to ensure that when the merging document operation ends, whether normally or abnormally, the Quit() method of the COM object is forcibly called, and pythoncom.CoUninitialize() is executed to perform memory cleaning, so as to minimize the risk of memory leakage.

[0036] As can be known from the above description, the present embodiment introduces a global singleton manager, a double-silence setter, and a resource release controller, which significantly optimize the performance and stability of the document merging based on the COM objects: the global singleton manager ensures that only one COM instance of Word or Excel is created throughout the merging process and is reused efficiently, so that the reuse rate of the COM objects is increased by more than 300%, greatly reducing the startup overhead and system resource occupation; the double-silence setter synchronously closes the interface display and warning pop-up (Visible = False and DisplayAlerts = False) when the COM objects are obtained, to realize completely background silent running and avoid user interference; and the resource release controller registers the atexit function and listens to the application exit event, to forcibly call Quit() and execute pythoncom.CoUninitialize() when the program normally or abnormally terminates, to completely release the COM resources and effectively prevent memory leakage. The three work together to make the system have the advantages of high performance, high reliability, and low resource consumption in the high-concurrency and multi-format mixed merging scenarios.

[0037] Still referring to Figure 1As shown, in the embodiment, the document merging system further comprises an output and cleaning module, which is in communication connection with the checking and repairing module and is configured to save the output document, clean the temporary document, and release the COM resource. The document merging system further comprises a UUID temporary directory generator, an authority controller, and a physical destroyer, which are in communication connection with the output and cleaning module, the UUID temporary directory generator is configured to generate a unique temporary directory using UUID, and all temporary documents in the conversion process are operated in this directory, wherein the temporary document is a single document used in the process of merging the to-be-merged document or a document generated in the process of converting the document format; the authority controller is configured to set the system authority to be accessible only by the current user; and the physical destroyer is configured to, after the completion of the merging task, call shutil.rmtree to forcibly delete the entire temporary directory, so that the sensitive temporary file cannot be recovered and the security standards such as NIST SP 800-88 are met.

[0038] As can be known from the above description, the embodiment cooperates the output and cleaning module with the UUID temporary directory generator, the authority controller, and the physical destroyer to build a safe, reliable, and compliant temporary file management mechanism: the system generates a unique temporary directory using UUID during the merging process to ensure that there is no conflict when multiple tasks are run in parallel; the directory access authority is strictly limited to the current user by the authority controller to prevent unauthorized access; and the physical destroyer calls shutil.rmtree to forcibly and completely delete the entire temporary directory after the completion of the task, so that the sensitive intermediate file cannot be left or recovered, and the data security destruction standards such as NIST SP 800-88 are met. This way not only guarantees the isolation and privacy of the document processing process, but also significantly improves the security and compliance level of the system, effectively preventing information security risks caused by temporary file leakage.

[0039] The present application provides a document merging method, which comprises the following steps: introducing a plurality of to-be-merged documents into the document merging system according to claim 1; and performing merging processing on the plurality of to-be-merged documents by the document merging system.

[0040] In order to verify the effectiveness of the above embodiment, the inventors performed the following experiment: 1. High-fidelity merging process of Word documents based on Python and COM As Figure 7As shown, (1) the user selects multiple Word documents and determines the order through the GUI (GUI is graphical interface of document operation) in the document merging system; (2) the document merging system calls get_word_application() to obtain (or create) a silent Word COM instance; (3) the document merging system creates a new blank Word output document as the merging target; (4) loop processing each source file: a, if not the first document, insert a wdSectionBreakNextPage section break at the end of the output document; b, embed the content of the document to be merged into the current end of the output document; c, immediately set the LinkToPrevious property (previous section connection property) of the header and footer of the section where the newly inserted content is located to False to block format inheritance; d, after merging is completed, the header verification module can be optionally called for final scanning and repair; e, save the output document and release the COM resource.

[0041] 2. Merging process of mixed format documents to PDF (1) The user selects Word, Excel, and PDF mixed files; (2) The document merging system creates a temporary directory; (3) The file analysis and routing module judges each document to be merged, if it is a PDF, it is directly added to the list of PDFs to be merged; if it is a Word or Excel, the document format conversion module is started, and the corresponding COM interface is called in silent mode to convert it into a high-quality PDF temporary file, and the temporary file path is added to the list of documents to be merged; (4) Use the PDF document merger to merge all PDF files (original PDF + converted temporary PDF) in order; (5) Call the physical destroyer to securely delete the entire temporary directory; (6) Output the final merged PDF, which is the corresponding output document.

[0042] 3. Workflow of the verification and repair module (1) Trigger: automatically call the verification and repair module after the document merging module completes the merging process; (2) Traversal: loop through each section (Section) in the output document; (3) Diagnosis: for each section, check the LinkToPrevious state of its first page header, odd-even page header, and footer; (4) Repair: restore the original header content from the backup or source file to ensure correctness; (5) Generate a repair output document or record a log.

[0043] In summary, the present application proposes a system and method for intelligent batch merging of files, the core inventive concept of which is that through the combination of four technologies of "dynamic format conversion + forced section isolation + header inheritance chain blocking + automated post-verification", compared with the prior art, the present application has the following significant advantages: 100% format retention rate: through the dual mechanisms of section symbol isolation and header inheritance chain blocking, the industry problem of loss of headers and footers during merging of Word documents is successfully solved, achieving a retention rate of 100%, which is much higher than that of traditional tools (≤20%); True lossless merging of mixed formats: the original document format conversion module realizes lossless conversion and merging of Word, Excel and PDF into a single PDF, solving the problem of high failure rate (>95%) of mixed merging of market tools; Efficiency is greatly improved: through COM object reuse, multithreading and silent operation, the merging time of 80 documents is shortened from 180 seconds of traditional tools to 35 seconds, with an efficiency improvement of more than 80%; Industrial-grade stability and security: the COM object life cycle management mechanism reduces the risk of memory leakage by more than 83%, and the safety sandbox (i.e. global singleton manager, double silent setter and resource release controller) design ensures zero residual of temporary files, meeting the requirements of enterprise-level continuous operation and data security compliance. The experimental results are shown in Table 1.
