How to convert office 2 pdf via Conversion SDK

System requirements

Platform: Windows
Programming Language:  C,C++, C#, Java, Python, Nodejs
License Key requirement: ‘Office2PDF’ module permission in the license key

Conversion interface

Office2PDF provides three conversion interfaces: ConvertFromWord, ConvertFromExcel, ConvertFromPowerPoint.In Foxit PDF Conversion SDK, these interfaces are defined in the header file ”fs_office2pdf.h”.Take “ConvertFromWord” as an example to introduce interface parameters in Windows.(The parameters of the two interfaces “ConvertFromExcel” and “ConvertFromPowerPoint” are similar to “ConvertFromWord”.)

The parameters for the interface come in two varieties: file path and stream.

The file path parameters are as follows:

The stream parameters are as follows:
