Total Excel Converter

Convert WK1 to PDF Or PDF/A in Batch

The Total Excel Converter allows users to convert the WK1 spreadsheet format from Lotus 1-2-3 to PDF or PDF/A documents. Many old-school data managers will remember Lotus 1-2-3 from the 1980s and 90s, in the days when IBM ruled the PC world before Microsoft and Apple took over. These same users may have a collection of old spreadsheets in need of archiving. For that, we include WK1 conversions in our Total Excel Converter.


  • The Total Excel Converter interface follows logical folder layout that mirrors Windows' Explorer, so you can find files anywhere on your PC with no trouble. Once-complicated batch operations are as simple as clicking on a folder and selecting checkboxes.
  • Adjust the file name template to suit your conventions. Make changes to the paper size to work with any printer. Change the header and footer. Add images such as company logos to every page. Compress the file for more efficient archiving. You can tweak the resulting file until it meets your standards.
  • Create non-searchable PDF/A documents to discourage cutting-and-pasting of the text. Add encryption and digital signatures for an even greater level of security, disallowing any tampering of sensitive information.
  • WK1 to PDF or PDF/A conversions usually take a matter of seconds, and even the largest jobs take less than half an hour to complete.

CoolUtils Total Excel Converter changes more than just Excel files, but most database formats. There are 23 other formats other than PDF you can change those WK1 files into, including JPEG, MHT, ODS/T, DIFF, and CSV. You can try this software for 30 days free by clicking the button below, and licenses are just $49.90.
