You can use Free Spire.XLS library to easiy get the number of columns in an Excel sheet. At first, search and install free spire.xls via nuget. Second, use the following code to get the number of columns in a sheet. Workbook workbook = new Workbook(); workbook.LoadFromFile( "test.xlsx" ); Worksheet sheet = workbook.Worksheets[0]; int columnCount = sheet.Columns.Count();
