Excelize is a Go library for reading and writing Microsoft Excel spreadsheets in XLAM, XLSM, XLSX, XLTM, and XLTX formats.
The library solves the problem of programmatically working with Excel files in Go applications. It handles the complexity of the Office Open XML format by providing straightforward functions for creating, modifying, and reading spreadsheet documents. The tool supports files generated by Microsoft Excel 2007 and later, maintaining high compatibility with complex spreadsheet components. For applications that need to process large datasets, the library offers a streaming API to generate or read data from worksheets without loading entire files into memory.
Developers should choose this tool when building Go applications that need native Excel file support without external dependencies. It suits projects ranging from simple spreadsheet generation to complex data processing pipelines. The library is particularly valuable for applications handling large volumes of spreadsheet data, where the streaming API prevents memory constraints. Beyond basic read and write operations, the tool provides capabilities for adding charts and images to spreadsheets, making it suitable for report generation and data visualization tasks.
The project maintains active development with continuous integration testing and code coverage monitoring. Pull requests are welcomed for bug fixes and feature discussions, indicating an open contribution model. The codebase adheres to the ECMA-376 Standard for Office Open XML, ensuring standards compliance and long-term compatibility.
