[0047] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.
[0048] In a typical configuration of the present application, the terminal and the equipment of the service network each include one or more processors (CPU), input / output interface, network interface and memory.
[0049] The memory may include non-permanent storage in a computer-readable medium, random access memory (RAM) and / or non-volatile memory in the form of read-only memory (ROM) or flash RAM. The memory is an example of a computer-readable medium.
[0050] Computer readable media include permanent and non-permanent, removable and non-removable media, and can be implemented by any method or technology to store information. Information can be computer program instructions, data structures, modules of programs or other data. Examples of computer storage media include, but are not limited to, phase change memory (PRAM), static random access memory (SRAM), dynamic random access memory (DRAM), other types of random access memory (RAM), read-only memory (ROM), electrically erasable programmable read-only memory (EEPROM), flash memory or other memory technology, read-only compact disk (CD-ROM), digital versatile disk (DVD) or other optical storage, magnetic cassettes, magnetic tape disk storage or other magnetic storage devices or any other non-transmission media that can be used to store information that can be accessed by a computing device.
[0051] In actual scenarios, the execution subject of the method can be a user device, or a device formed by integrating a user device and a network device through a network, or an application running on the above device. The user device includes but is not limited to various terminal devices such as computers, mobile phones, tablet computers, smart watches, and bracelets.

Here, the cloud is composed of a large number of hosts or network servers based on cloud computing, where cloud computing is a type of distributed computing, a virtual computer composed of a group of loosely coupled computer sets.
[0052] The data of the existing voucher attachments are all present in the exported spreadsheet, which has several columns of data. Printing all of them will cause the layout (A4 paper displayed horizontally) to be crowded or incomplete on one page. During manual operation, the practices of companies in different cities are not exactly the same. Some will retain all columns, while others will delete several columns of unimportant data to make the content of the printed page reasonably distributed and displayed completely on one page. This will result in inconsistent formats of the summarized tables.
[0053] Figure 1 A schematic diagram of a method for making an electricity bill voucher is provided in accordance with an embodiment of the present application. Figure 1 As shown, the method includes:
[0054] S101, obtaining electricity charge source file information.
[0055] Specifically, the electricity bill source files include the electricity bill transfer slips, electricity bill refund slips, salesman's charging details and cashier's daily charging details of each subsidiary. It is necessary to produce at least eight electricity bill voucher electronic spreadsheets based on these electricity bill source files. For example, different electronic vouchers can be produced according to different charging items in the electricity bill source files, and different electronic vouchers can be produced according to different settlement methods or different charging types. Figure 2 An electricity fee source file diagram provided in an embodiment of the present application, such as Figure 2 As shown, the electricity fee source file is the toll collector's daily fee list, which contains multiple columns of important information such as the power supply unit, toll collector, payment method, settlement method, etc. When making an electricity fee voucher, it is necessary to generate a separate spreadsheet according to different columns and process and calculate according to the preset format.
[0056] First, name the electricity bill source file in a specific format. You can set the name in the system so that the electricity bill source file exported from the system is automatically named according to the naming requirements. Then open these electricity bill source files, use the VB programming language to edit and run the code, use the Private Sub Workbook_Open() code to start the background program, assign the source document file name exported by the system to the two-dimensional array Mar_arr(), and you can add new source document file names to the array at any time, which is easy to expand. Use the Call command to traverse the file names started, record the exported and opened source document workbook information into the dynamic array M_sheet(), match it with the correct file name in the background, and determine whether it contains the required electricity bill source file. If the required source files are not all opened, the program will pop up a window prompting "Please open the source document exported from the marketing system first."
[0057] Preferably, the software is run as a "macro" file, so it is necessary to set up the trusted software in the "Security Settings" of the spreadsheet software in advance, or select the "Enable Macro" button in the pop-up warning window each time you double-click to run the software.
[0058] S102: Classify the electricity fee source file information and filter out the information required for the electricity fee voucher.
[0059] Specifically, first call the electricity bill voucher template corresponding to the required electricity bill voucher, then call the data processing function, collect and filter out the data information required in the electricity bill voucher template from the electricity bill source file, and copy this information to the background clipboard, and finally classify the information in the clipboard according to the required data in each electricity bill voucher template.
[0060] Figure 3 An electricity bill voucher diagram provided in an embodiment of the present application, such as Figure 3 As shown, for example, if an electricity bill voucher template is internal bill_refund, the data information with the charge type of refund in the filtered data information is classified into one category.
[0061] S103: Convert the filtered information into electricity bill vouchers and output and display them.
[0062] Specifically, to paste the classified data information into the corresponding electricity bill voucher template, first identify the cell area to be pasted, define internal variables and assign values, and then select the corresponding data information in the clipboard and paste it into the area, for example Figure 3 , paste the data information with charge type as refund from the clipboard to the electricity bill voucher template of internal bill_refund, and then paste the cell area with the same row information with charge type as refund in the clipboard into the template according to the content of the column in the template of internal bill_refund.
[0063] After pasting is completed, the data information in the template is sorted, for example, in order of date, power supply unit, amount, etc. After sorting, the data information is calculated accordingly according to the preset formula in the electricity bill voucher template to obtain the result. For example, if the template needs to count the total amount, the column where the amount is located after sorting is summed and the result is counted. Finally, the entire template is adjusted according to the preset format requirements, such as setting different column widths and line spacing according to the content of the cell, adjusting the font size, etc., so that the adjusted electricity bill voucher meets the printing and binding requirements, and ensures that the number of lines per page of the printed voucher is the same. Preferably, the administrator can set whether to generate a print preview. If you choose to generate, the print preview interface will pop up.
[0064] Preferably, the electricity bill voucher template-related codes are updated regularly to ensure the accuracy of the calling template.
[0065] Table 1
[0066]
[0067] Table 1 is a comparison table of the time taken for manual production and software production, wherein documents ABCD are 4 source files, and 8 electricity bill vouchers are produced through these 4 source files. It can be seen from the table that the time taken for producing electricity bill vouchers using the software constructed using the method of the present invention is hundreds of times shorter than that for manual production, and the expected result is fully achieved.
[0068] In the method provided in the embodiment of the present invention, an electricity bill voucher template is produced by designing software, and an electricity bill voucher is generated with one click, which shortens the time several times compared with manual production, greatly improves the efficiency of voucher production and review, and greatly reduces the workload of manual production of attachments; and the voucher production is automatically generated by the program, which can realize automatic typesetting, eliminates data errors that may be caused by manual operation, reduces the production error rate, and improves the work quality.
