Convert WKS to XLS (Excel)

The WKS file extension represents Microsoft Works Spreadsheet, a part of the Microsoft Works suite. First introduced in 1987, Works was designed as a streamlined, affordable alternative to Microsoft Office. The WKS format specifically handled spreadsheet data, facilitating tasks such as budgeting, data analysis, and inventory management. Despite its simplicity, it enabled users to perform essential functions like data sorting, basic calculations, and charting. Over time, Microsoft phased out Works in favor of the more advanced Office suite, yet WKS files remain a legacy format, occasionally encountered in archival data and older systems.

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.
