FAQ
XLS to JXL Conversion
What are XLS files?
XLS is the older Microsoft Excel spreadsheet file. It was the standard format of Excel from version 97 to Excel 2003, and it stores tables with numbers, text, dates, formulas, charts, and formatting, in one or several sheets. Modern Excel still opens it, but new files are saved as XLSX, which is smaller and holds far more data. A great number of price lists, reports, and accounting tables made before 2007 are still XLS files.
