How to read excel file using pure C?

Question

As the title said, I have a task that I need to read data from excel files. I'm wondering how to implement it in pure C, not C++ or C#. Btw, I need to write and test the program in Linux but others may use the code in Windows, which means my code has to be OS independent. Thank you.
