Excelize is an open-source library written in Go for reading from and writing to Microsoft Excel spreadsheet files. It supports spreadsheet formats such as XLAM, XLSM, XLSX, XLTM, and XLTX.[4] It implements the Office Open XML standard (ECMA-376 and ISO/IEC 29500).[5]
History
[edit]The first commit to the Excelize GitHub repository was made on August 30, 2016. A book about the library, Excelize 权威指南 (Excelize: The Definitive Guide), was published to cover its architecture and usage.[6]
Features
[edit]Excelize can read and modify documents generated by Microsoft Excel 2007 and later. Its features include:
- File processing: Creating, reading, and modifying spreadsheets without requiring Microsoft Office.[7]
- Streaming API: A streaming API for reading and writing data in large files to reduce memory usage.
- Workbook elements: Support for inserting charts, pivot tables, and data validation, as well as cell formatting.[8]
- Encryption: Support for encrypting and decrypting Compound File Binary (CFB) formats. Supported algorithms include MD4, MD5, RIPEMD-160, SHA1, SHA256, SHA384, and SHA512.[9]
Security
[edit]In July 2026, a Denial of Service (DoS) vulnerability (CVE-2026-54063) was found in Excelize versions prior to 2.11.0.[10]
The vulnerability was located in the `checkSheet` function used for parsing worksheets, which did not validate row indices against Excel's maximum row limit of 1,048,576. Specially crafted XLSX files could cause high memory allocation, leading to application crashes.[11] The issue was fixed in version 2.11.0 by adding bounds checking for worksheet structures.[10]
Example usage
[edit]The following is a minimal code example in Go demonstrating how to generate a new Excel spreadsheet, input data into cells, and save the file:[8][12]
f := excelize.NewFile()
defer func() {
if err := f.Close(); err != nil {
fmt.Println(err)
}
}()
// Create a new worksheet named "Sheet2"
index, err := f.NewSheet("Sheet2")
if err != nil {
fmt.Println(err)
return
}
// Set values for cells
f.SetCellValue("Sheet2", "A2", "Hello world.")
f.SetCellValue("Sheet1", "B2", 100)
// Set the active sheet for the workbook
f.SetActiveSheet(index)
// Save the spreadsheet file
if err := f.SaveAs("Book1.xlsx"); err != nil {
fmt.Println(err)
}
