Converting XLSB to XLSX without using Microsoft.Interop.Excel

As mention in title, is there any other ways I can use to convert XLSB to XLSX without using Microsoft.Interop.Excel?

I have check ExcelDataReader, EPPlus, CSharpJExcel, and NPOI and it does not support XLSB.

Solution

  • EasyXLS is a library that supports both xlsb and xlsx files.

    The below code is what you need for conversion:

    ExcelDocument workbook = new ExcelDocument();
workbook.easy_LoadXLSBFile("Excel.xlsb");
workbook.easy_WriteXLSXFile("Excel.xlsx");
