What You Can Do with Aspose.Cells FOSS for Go

Out-of-the-box spreadsheet processing features include:

  • Create new workbooks and worksheets from scratch, or load and modify existing .xlsx files
  • Read and write individual cells through the Cells() collection (Cells().Get(ref) / Cells().Set(ref, value))
  • Apply cell styles: font, fill, alignment, and border via reusable Style objects
  • Attach list and whole-number data validation rules with custom error messages
  • Build structured Table ranges with a header row and named table style
  • Embed pictures with Worksheet.AddPicture
  • Export to and import from CSV
  • Stream large workbooks row by row with StreamingReader, without loading the whole sheet into memory
  • Protect workbooks with a password (Workbook.SetPassword/VerifyPassword)

Basic Example

Here is a simple example that creates a workbook, writes a few cells, and saves it as .xlsx:

func main() {
	wb := cells_foss.NewWorkbook()
	ws := wb.Worksheets[0]
	ws.Cells().Set("A1", "Hello")
	ws.Cells().Set("B1", "World")
	ws.Cells().Set("A2", "Answer")
	ws.Cells().Set("B2", 42)
	outPath := "outputfiles/basic.xlsx"
	if err := wb.Save(outPath); err != nil {
		fmt.Printf("Error saving workbook: %v\n", err)
		return
	}
	fmt.Printf("Workbook saved to %s\n", outPath)
}
