How to convert WK1 to CSV
- Add your .WK1 file - drop it in the box above or click to browse.
- Convert it to .CSV in a few seconds.
- Download your new .CSV file.
What to expect
- Only cell values are kept; formulas become static results and all formatting, multiple sheets, and charts are lost.
- CSV holds a single flat table, so a multi-sheet WK1 workbook cannot be represented in one file.
- Numbers and dates export as plain text, and how they display later depends on the locale settings of whatever opens the CSV.
Frequently asked questions
What survives when converting a WK1 worksheet to CSV?
Only the cell values survive - the plain text and numbers from the worksheet grid. Formatting, fonts, column widths, and any charts are dropped because CSV stores only raw tabular data.
Why convert WK1 to CSV?
WK1 is a proprietary Lotus 1-2-3 binary format that modern Excel no longer opens, while CSV is plain text that every spreadsheet program reads. CSV is the most portable way to rescue the data from an obsolete format.
Where can I open the resulting CSV?
Any spreadsheet or text tool - Excel, Google Sheets, LibreOffice Calc, or a plain text editor. The trade-off for that universality is that CSV holds no formulas or formatting.
Are formulas kept as formulas?
No. Formulas in the WK1 sheet are converted to their calculated results, since CSV cannot store formula logic - only the final values appear in the file.
