Convert fixed-width text to CSV.
Paste column-aligned text (mainframe reports, legacy log formats, fixed-width exports). We auto-detect the column boundaries — or set them manually if our guess is wrong.
Paste column-aligned text (mainframe reports, legacy log formats, fixed-width exports). We auto-detect the column boundaries — or set them manually if our guess is wrong.
Fixed-width files are still everywhere — legacy systems, financial extracts, mainframe reports. This converter analyzes the whitespace pattern of your input to find column boundaries automatically. If the auto-detect misses, override it with explicit character positions (e.g. <code>10, 25, 40</code> means cuts after column 10, 25, and 40).
Drag a file, click to choose, or paste data directly into the input pane.
Types are inferred so the output is correctly formatted — not strings everywhere.
Copy the output, download it, or hit 'Build dashboard' to chart what's in the data.
Free CSV converters often produce sloppy output — every value quoted, types lost, errors swallowed. Ours infers types where it can, fails loudly when it can't, and pairs the conversion with a one-click path to a dashboard.
Numbers, booleans and dates are detected as you import, so the CSV (and any dashboard built from it) treats them correctly — not everything as text.
Your file is parsed and converted in your browser — verify in DevTools → Network. Nothing is uploaded, logged, or stored.
Malformed input gives a clear, specific error instead of silently wrong output — so you can trust what comes back.
Every conversion keeps a tabular copy, so you can send the data straight to our visualization tool to chart it.
