A WK4 file is a spreadsheet file format associated with Lotus 1-2-3, a historical spreadsheet software developed by Lotus Development Corporation. The WK4 file format is an extension used for spreadsheet files created and saved in Lotus 1-2-3 version 4.x. Similar to WK1 and WK3 files, WK4 files contain data organized in rows and columns, including numerical data, formulas, text, and formatting.
What is a WK4 File?
A WK4 file is a spreadsheet file that represents a workbook in Lotus 1-2-3 version 4.x. Lotus 1-2-3 was widely used in the 1980s and 1990s, and WK4 files may contain more advanced features compared to earlier versions, providing additional capabilities for data organization and analysis.
How to Open WK4 Files:
Opening WK4 files can be challenging in modern times, as Lotus 1-2-3 is considered outdated and no longer widely supported. However, there are still a few methods to access the data within WK4 files:
1. Use Lotus 1-2-3:
- If you can obtain an older version of Lotus 1-2-3, you may be able to open WK4 files directly. However, finding a compatible version can be difficult, as the software is no longer actively developed.
2. Convert to a Modern Format:
- Convert WK4 files to a more modern and widely supported format like Microsoft Excel’s XLS or XLSX. Various online converters or third-party tools may assist in this conversion process.
3. Use Spreadsheet Software:
- Open WK4 files using modern spreadsheet software such as Microsoft Excel, Google Sheets, or LibreOffice Calc. These applications often have import features that can handle legacy file formats.
