Convert XLW to XLS (Excel)

The XLW file extension stands for Microsoft Excel Workspace, a format used by Microsoft Excel to save the screen locations of multiple open workbooks, allowing users to restore their layout upon reopening. Introduced in earlier versions of Excel, this feature was discontinued from Excel 2013 onwards, though existing XLW files can still be opened. The primary use of XLW files was to enhance productivity by maintaining an organized workspace with multiple workbooks.

The XLS file extension, short for "Excel Spreadsheet", is a legacy format used by Microsoft Excel for storing spreadsheet data. Introduced with Excel 2.0 in 1987, it was the primary format until the introduction of XLSX in 2007. XLS files contain data organized in rows and columns, supporting formulas, macros, and various formatting options, making them essential for data analysis and financial reporting. Despite being replaced by the more robust and secure XLSX format, XLS files remain widely used in many legacy systems and applications.
