Where can I find a C library to read Excel and/or ODS files?

Googling for "ods c libra开发者_如何学运维ry" doesn't lead any useful results.

This is only in its experimental status yet, but the idea behind it is to replace the LibreOffice Calc filters by an external Library. The developer is the main LibreOffice Calc developer. The OpenOffice and LibreOffice Calc filter use all UNO and are dependent on the Calc core design.

you could try libxl although that is C++ (multi platform, but xls/xlsx)
