Convert WK4 to DIF

The WK4 file extension, short for Lotus 4 Worksheet, was developed by IBM for its Lotus 1-2-3 spreadsheet software. These files store data in cells organized into rows and columns, similar to modern spreadsheets. Primarily used for data entry and accounting, WK4 files have become less common with the discontinuation of Lotus 1-2-3. While older versions of Microsoft Excel could import WK4 files, this support was dropped in Excel 2007 and later. Today, specialized converters or older spreadsheet programs like Gnumeric can still open WK4 files.

The Data Interchange Format (DIF) file extension is a standardized format used primarily for importing and exporting spreadsheet data between different software applications. Originating in the 1980s, DIF was developed by Software Arts for their pioneering spreadsheet program, VisiCalc. Despite its age, DIF remains relevant due to its simplicity and ease of implementation, facilitating interoperability among various data processing tools. Its structured, plain text nature makes it particularly suitable for transferring tabular data while maintaining data integrity across different platforms.
