A WK1 file is a spreadsheet file format associated with Lotus 1-2-3, one of the earliest spreadsheet software applications. Developed by Lotus Development Corporation, Lotus 1-2-3 was widely used in the 1980s and early 1990s before being succeeded by other spreadsheet programs like Microsoft Excel. The WK1 file extension specifically refers to spreadsheet files created and saved in the Lotus 1-2-3 version 2.x format.
