xlnt is a C++14 library for reading, writing, and modifying XLSX files as described in ECMA 376. The API is based on openpyxl, a Python library to read/write Excel 2007 xlsx/xlsm files, and ultimately on PHPExcel, pure PHP library for reading and writing spreadsheet files upon which openpyxl was based. This project is still very much a work in progress, but the core development work is complete.
