Convert WK1 to WK2

Understanding WK1 and WK2 file formats

WK1 and WK2 are spreadsheet file formats associated with Lotus 1-2-3, a popular spreadsheet application from the 1980s and 1990s. WK1 is the original Lotus 1-2-3 worksheet format, while WK2 is an updated version introduced with Lotus 1-2-3 Release 2, offering enhanced features and compatibility.

Why convert WK1 to WK2?

Converting WK1 files to WK2 format is often necessary for improved compatibility with newer versions of Lotus 1-2-3 or other spreadsheet applications that support the WK2 format but not WK1. The WK2 format also supports larger worksheets and additional features.

How to convert WK1 to WK2

The most reliable way to convert WK1 files to WK2 is by using legacy spreadsheet software that supports both formats. Here are the steps using Lotus 1-2-3 (Release 2 or later):

• Open Lotus 1-2-3.
• Go to File → Open and select your WK1 file.
• Once the file is loaded, go to File → Save As.
• In the file type options, choose WK2 as the target format.
• Save the file with a new name or overwrite the existing one.

Best software or converter for WK1 to WK2

Lotus 1-2-3 Release 2 or later is the best software for this conversion, as it natively supports both formats. If you do not have access to Lotus 1-2-3, you can try Gnumeric (an open-source spreadsheet program) or LibreOffice Calc, though support for WK1 and WK2 may be limited and not all features may be preserved.

Tips for successful conversion

• Always back up your original WK1 files before conversion.
• Check the converted WK2 file for formatting or data issues.
• If using modern software, ensure you have the latest version for best compatibility.
