.WKU File

The wku file extension is associated with Lotus 1-2-3, a spreadsheet editor for Windows, DOS and other platforms.

The wku files were used by Lotus 1-2-3 spreadsheets.

Mime types:
application/vnd.lotus-1-2-3
application/x-123

This wku file type entry was marked as obsolete and no longer supported file format.

This type of file is no longer actively used and is most likely obsolete. This is typically the case for system files in old operating systems, file types from long discontinued software, or previous versions of certain file types (like documents, projects etc.) that were replaced in higher versions of their original programs.

A wku file extension is related to the Lotus 1-2-3 spreadsheet program. A wku file contains spreadsheet.

How to open:

Use Lotus 1-2-3 to open the .wku files. Also some spreadsheets programs can still open the .wku files, however the latest Microsoft Excel 2007/2010 no longer support this format. You can have luck with any earlier version of Excel, but you will probably loose some of the formatting from the .wku files.

How to convert:

Lotus 1-2-3 may be able to export *.wku files to other formats.
