Supported files and tested scope

The app lists Lotus 1-2-3 .123, .wk1, .wk3, .wk4 and .wks, and Quattro Pro .wb1, .wb2, .wb3, .wq1 and .wq2. The tested files include Lotus 1-2-3 for DOS, Release 3 and 97/Millennium, and Quattro Pro for DOS and Windows 1 to 6.

A real .wb3 sample has not yet been verified. A genuine Lotus Release 4 .wk4 sample has not yet been verified either; the available .wk4 sample is a Microsoft Works for Mac spreadsheet. Listed support does not guarantee that every file will open. Quattro Pro .qpw is outside this version's supported file list.

Good to know

This is a viewer and converter. It does not edit Lotus or Quattro Pro files.
Cells show values saved in the file. Formulas are not recalculated and macros are not run. Do not rely on the preview to refresh old calculations.
Pages are rebuilt locally. Column widths, fonts, charts and drawings can differ from the original.
Very large sheets can span several printable pages and take longer to open.
Password-protected files cannot be opened. The app does not remove passwords.
Damaged files or files that are not real supported spreadsheets show a message instead of broken text.

Private by design

Your files are processed on your PC and never uploaded. Local temporary files are used to display the spreadsheet; exports are saved where you choose. Microsoft Store handles Pro purchases and license verification. Read the Privacy Policy.

For Works .wks spreadsheets, WPD File Viewer is another option. The .wks extension is shared by different spreadsheet formats.
