Question 1

How to add a chart to an Excel file using Excelize in Go?

Accepted Answer

Use the f.AddChart() method with parameters for chart type, series, and categories based on worksheet data. The README provides a clear example for creating 3D clustered column charts, including setting up data ranges and titles.

Question 2

Excelize vs tealeg/xlsx: which Go library is better for Excel files?

Accepted Answer

Excelize generally offers more features like streaming API and chart support, making it better for complex automation. tealeg/xlsx might be simpler for basic reading/writing, but Excelize is preferred for modern formats and performance with large datasets.

Question 3

Can Excelize handle Excel files with macros (XLSM)?

Accepted Answer

Yes, Excelize supports reading and writing XLSM files, which are macro-enabled workbooks. However, it focuses on file format compatibility rather than executing or editing VBA macros, so advanced macro manipulation may require additional tools.

Question 4

How to read large Excel files efficiently with Excelize?

Accepted Answer

Utilize the streaming API by using methods like f.GetRows() with streaming options to process data row by row. This avoids loading the entire file into memory, as emphasized in the key features for handling massive datasets.

Question 5

Does Excelize support adding formulas to cells?

Accepted Answer

Yes, Excelize allows setting cell formulas using f.SetCellFormula(), enabling calculations within spreadsheets. However, complex formula evaluation or dependency tracking might need custom implementation beyond basic insertion.

Question 6

How to install Excelize in a Go project with modules?

Accepted Answer

Run 'go get github.com/xuri/excelize/v2' for projects using Go Modules, as specified in the installation section. Ensure you have Go 1.25.0 or later, which is a requirement mentioned in the README.
