Convert WK4 to PDF

How to convert WK4 to PDF

1. Add your .WK4 file - drop it in the box above or click to browse.
2. Convert it to .PDF in a few seconds.
3. Download your new .PDF file.

What to expect

• Excel 2007 and later cannot open .wk4 files - Microsoft removed the Lotus import filter; use LibreOffice or ABC Amber tools instead.
• PDF export captures displayed cell values (formula results), not the formulas themselves - this is standard behavior for any spreadsheet-to-PDF export.
• WK4 supports multi-sheet workbooks; LibreOffice exports all sheets into a single PDF by default, so check the page range settings if you only need specific sheets.

Frequently asked questions

Can I open WK4 in Microsoft Excel?

No - Excel 2007 and later dropped the Lotus .wk4 import filter entirely. Use LibreOffice Calc, which still ships the Lotus importer.

Will my formulas be visible in the PDF?

No. PDF export captures the calculated values shown on screen, not the formula text - this is standard behavior.

Can I convert multiple WK4 files at once?

Yes - LibreOffice CLI accepts wildcards, so soffice --convert-to pdf *.wk4 processes an entire folder in one command.

Are password-protected WK4 files supported?

LibreOffice can open some sealed WK4 files, but Lotus used a weak protection scheme and results vary - there is no guarantee.
