Batch XLS and XLSX Converter

An easy-to-configure program that helps you convert XLS files to XLSX format or vice versa while allowing you to pause or stop the process. It supports powerful searching of many files.

XLS and XLSX are two file extensions used by Microsoft Excel. Microsoft Excel 2003 documents are XLS, while the 2007 edition works with the XLSX format. Although both formats belong to the same company, you may have trouble opening XLS files with the 2007 set and XLSX data with the 2003 version. To avoid such a situation, you can use Batch XLSX To XLS Converter.

Thus, with the help of this application, you can easily convert only a selected file or all the Excel 2007 or 2003 files that are located in a particular folder. You can export the current project to a batch xls2xls file to save the task for later.
