Convert XLSM to WK4

Understanding xlsm and wk4 file formats

XLSM is a macro-enabled spreadsheet file format used by Microsoft Excel. It supports advanced features such as macros, formulas, charts, and complex data manipulation. WK4 is a spreadsheet file format used by Lotus 1-2-3 version 4, a popular spreadsheet application from the 1990s. WK4 files are now considered legacy, but may still be required for compatibility with older systems.

Why convert xlsm to wk4?

Converting XLSM to WK4 is necessary when you need to share or migrate data to environments that only support Lotus 1-2-3 or its compatible software. This is common in organizations with legacy systems or for archival purposes.

How to convert xlsm to wk4

Direct conversion from XLSM to WK4 is not natively supported by modern spreadsheet software. However, you can use a two-step process:

1. Open your XLSM file in Microsoft Excel.
2. Save the file as an XLS (Excel 97-2003 Workbook) via File → Save As → Excel 97-2003 Workbook (*.xls).
3. Open the XLS file in LibreOffice Calc or an older version of Microsoft Excel that supports legacy formats.
4. Export or save the file as WK4 via File → Save As → Lotus 1-2-3 (*.wk4) (if available).

If you do not have access to older Excel versions, LibreOffice Calc is the best free software for this conversion, as it still supports exporting to WK4 format.

Recommended software for xlsm to wk4 conversion

• LibreOffice Calc – Free and open-source, supports both XLS and WK4 formats.
• Microsoft Excel (older versions) – May support WK4 export if you have access to legacy versions.

Online converters for this specific conversion are rare due to the legacy nature of WK4. For best results, use desktop software like LibreOffice Calc.

Important considerations

• Macros and advanced features in XLSM will not be preserved in the WK4 format, as Lotus 1-2-3 does not support Excel macros.
• Formatting and formulas may be lost or altered during conversion due to differences in file capabilities.
• Always verify the converted WK4 file for data integrity and formatting.
