Abstract

The invention relates to a method for converting Excel files into JSON files, belonging to a file format conversion technology, comprising the following steps: step A: receiving Excel data requested by a client; B, reading that data in the Excel data in the form of a Datatable, traversing the Datatable data as List, and finally reverse sequence the List to obtain JSON data; C, receiving the HTTP request sent by the client end, reading the basic element information in the JSON file, and then arranging the information according to the typesetting format of the EXCEL file and obtaining the typesetting result; D, cal that C + + language function library to generate an EXCEL file from the typesetting result, and sending the EXCEL file to the client after obtaining the EXCEL file. Compared withthe prior art, the method converts Excel files into JSON files for network HTTP requests is convenient to use, is easy to read and write, is easy to machine parse and generate, and effectively improves network transmission efficiency.

Description

technical field [0001] The invention relates to a file format conversion technology. Background technique [0002] Excel is a commonly used tool for everyone, and it is very convenient for data editing. However, the original method of direct reading using Excel is error-prone, and it is difficult to query and obtain specified columns through query conditions. It is inefficient, inconvenient to obtain results through HTTP requests, and inconvenient to use. JSON (JavaScriptObjectNotation) is a lightweight data exchange format based on a subset of ECMAScript. JSON uses a completely language-independent text format, but also uses a habit similar to the C language family (including C, C++, C#, Java, JavaScript, Perl, Python, etc.), these features make JSON an ideal data exchange language, easy for humans to read and write, and easy for machines to parse and generate. Sometimes, we need to convert Excel data into JSON format for subsequent use. Contents of the invention [000...
