Text to CSV Column Mapper
Convert delimited text (pipe, comma, tab, or space) into CSV with renameable columns and a live table preview. Runs entirely in your browser.
🔒 This tool runs entirely in your browser. Your files are never uploaded to a server.
How it works
- Paste your delimited text and choose the delimiter it uses.
- Optionally treat the first row as a header, and rename any column.
- Preview the result as a table, then copy or download it as CSV.
FAQ
What kinds of delimited text does this handle?
Any consistent delimiter — pipes, commas, tabs, semicolons, or spaces — commonly found in log files, fixed-format exports, or text copied from a non-spreadsheet source.
Why rename columns instead of just using the header row?
Some source text has no header row at all, or has header names you'd rather change before exporting — renaming lets you set clean, final column names either way.
What happens if rows have different numbers of fields?
The tool uses the widest row to determine the column count; shorter rows get blank values for any missing trailing columns.
Is my data uploaded anywhere?
No — parsing and conversion happen entirely in your browser. Nothing is sent to a server.
How we compare
| Feature | Online Tool Store | Spreadsheet "Text to Columns" | Manual regex/script |
|---|---|---|---|
| Live table preview while editing names | ✓ | Requires importing into a sheet first | No visual preview |
| No spreadsheet needed | ✓ | Requires Excel/Sheets | ✓ |
For a quick paste-map-export from a log file or oddly-formatted export, this beats opening a spreadsheet or writing a parsing script.
