Help how to open:

Use Lotus 1-2-3 version 1.x or later to open the .wks files.

Also some modern spreadsheets programs can still open the .wks files. However the latest versions of Microsoft Excel 2007/2010 no longer support that format. You can have luck with any earlier version of Excel, but you will probably lose most of the formatting from the .wks files.

How to convert:

You can open *.wks in Microsoft Excel and save it to another file format. You will probably lose formatting.
