Microsoft Works Spreadsheet for Mac (.wps)
The WPS file extension, associated with Microsoft Works for Mac, was primarily used for spreadsheet documents. Initially launched in 1988, it was Microsoft's default format for Microsoft Works Spreadsheets. The format was discontinued in 2006, with the evolution toward modern file types like XLS and XLSX. Nowadays, WPS files are considered legacy formats but can still be accessed and converted using compatible software tools.
