Convert FM3 to WK1

Understanding the fm3 and wk1 file formats

FM3 files are associated with Lotus 1-2-3 spreadsheet software, specifically version 3. These files store spreadsheet data, formulas, and formatting. WK1 files are also Lotus 1-2-3 spreadsheet files, but they correspond to version 2.x. While both formats are used for spreadsheets, WK1 is more widely supported by modern spreadsheet applications for import and conversion.

Why convert fm3 to wk1?

Converting FM3 to WK1 is often necessary for compatibility with newer spreadsheet software or data migration. Many modern applications can open WK1 files, but may not support FM3 directly.

How to convert fm3 to wk1

Since both formats are legacy Lotus 1-2-3 files, the best approach is to use software that supports both formats. Lotus 1-2-3 itself is the most reliable tool, but it is no longer officially available. Alternatively, LibreOffice Calc can open WK1 files, but may not support FM3 directly. If you have access to Lotus 1-2-3:

• Open your FM3 file in Lotus 1-2-3.
• Go to File → Save As.
• Select WK1 as the target format.
• Save the file.

If you do not have Lotus 1-2-3, consider using a virtual machine with DOS and Lotus 1-2-3 installed, or seek out specialized legacy file conversion services.

Recommended software for fm3 to wk1 conversion

• Lotus 1-2-3 (version 3.x or later): Best for direct conversion.
• Legacy file conversion services: Online services or data recovery companies may assist if you lack the original software.

Unfortunately, there are no modern, free converters that support FM3 to WK1 directly. Using the original Lotus 1-2-3 software remains the most reliable method.
