You are trying to read xls with explicit implementation poi classes for xlsx   G  Selenium Jar Files TestData Data xls  Either use HSSFWorkbook and HSSFSheet classes or make your implementation more generic by using shared interfaces  like   Change   XSSFWorkbook workbook   new XSSFWorkbook file     To    org apache poi ss usermodel Workbook workbook   WorkbookFactory create file     And Change   XSSFSheet sheet   workbook getSheetAt 0     To   org apache poi ss usermodel Sheet sheet   workbook getSheetAt 0

You are trying to access an XLS file  However  you are using XSSFWorkbook and XSSFSheet class objects  These classes are mainly used for XLSX files   For XLS file  HSSFWorkbook  amp  HSSFSheet For XLSX file  XSSFSheet  amp  XSSFSheet  So in place of XSSFWorkbook use HSSFWorkbook and in place of XSSFSheet use HSSFSheet    So your code should look like this after the changes are made   HSSFWorkbook workbook   new HSSFWorkbook file    HSSFSheet sheet   workbook getSheetAt 0
