libxlsxwriter is an ANSI C library for creating Excel 2007+ XLSX files with text, numbers, formulas, hyperlinks, charts, images, and full formatting. It has minimal dependencies (only zlib) and works across many compilers and platforms.

Use cases

• generate excel xlsx reports from c
• write spreadsheets with charts and formatting in c
• export data to excel files on linux or windows
• create large xlsx files with low memory usage
• add macros and images to excel workbooks programmatically

When to choose

• you need to generate Excel-compatible XLSX files from C or C++ code
• you want a lightweight library with only a zlib dependency
• you need rich Excel features like charts, conditional formatting, and data validation
• you must run on many platforms, compilers, and endianness configurations

When to avoid

• you need to read or parse existing XLSX files rather than create them
• you are working in Python, JavaScript, or another high-level language with native alternatives
• you need to edit legacy .xls binary Excel files
