What is it?

Excelize is a Go library for reading and writing spreadsheet files in the Office Open XML family, including XLSX, XLSM, XLSB-free macro-enabled and template variants such as XLTM, XLTX and XLAM. It targets files produced by Microsoft Excel 2007 and later, and it is written in pure Go, so it runs without Office or any external runtime.

The API covers creating workbooks, setting and reading cell values, managing sheets, and inserting charts and pictures. A streaming API is available for writing or reading worksheets with very large amounts of data. XML handling follows part 1 of the 5th edition of the ECMA-376 standard.

The package is imported as github.com/xuri/excelize/v2 and documented on pkg.go.dev and on the project's docs site.
