File format conversion method and device and computer readable storage medium

The invention relates to the field of file format conversion, and discloses a file format conversion method and device and a computer readable storage medium. The file format conversion method comprises the steps of reading a first format file; analyzing the first format file, and storing an analysis result in an application program development library; converting variables in the application program development library into variables in a second format one by one according to a second format file protocol; and outputting the variables in the second format and generating a second format file.According to the scheme, format conversion is carried out on the file based on the application program development library, the application program development library file can efficiently and accurately process variables of different formats, the data processing time is greatly shortened, the overall data conversion efficiency is improved, and hidden danger existing in manual file format conversion is avoided. 本发明涉及文件格式转
