What is a .WK3 file?

The file extension .WK3 is associated with a Lotus 3 Worksheet, which is a type of spreadsheet file. This file format was created by the software Lotus 1-2-3, specifically for its version 3. In a .WK3 file, data is stored within cells that are arranged in a structured format of rows and columns, similar to a table. This setup allows for efficient organization and manipulation of data, making it suitable for various data-entry and analytical tasks.

Although the software IBM Lotus 1-2-3 that originally created and used this file format has been discontinued, you can still open .WK3 files with some older versions of other programs. Notably, Microsoft Excel, up to the 2003 version, supports opening this type of file. This means if you have Microsoft Excel 2003 or an earlier version installed on your computer, you should be able to view and edit .WK3 files. However, newer versions of Microsoft Excel do not support this format directly. If you need to work with .WK3 files and do not have access to the compatible versions of Excel, you might consider converting them to a more current file format or using a file conversion tool.
