What is a WLS file?
A WLS file is a spreadsheet created by 602Tab, a Microsoft Excel alternative included with Software602 602PC SUITE. It contains data that appears in a grid of horizontal rows and vertical columns when viewed in a spreadsheet program. WLS files are compatible with Microsoft Excel.
602PC SUITE was a Czech productivity suite that mimicked Microsoft applications. It contained 602Text, a text editor, and 602Tab, a spreadsheet program. 602Tab saved users' spreadsheets as WLS files. (602Text saved users' documents as .WPD files.)
In 2004, 602 Software discontinued 602PC SUITE and replaced it with 602Office, which was developed using open source code contained in Apache OpenOffice. 602Office is now also discontinued.
How to open a WLS file
If you still have access to 602Tab (Windows), you can open your WLS file in that program. Otherwise, you may be able to open your WLS file in Microsoft Excel (Windows, Mac) or another spreadsheet program.
