CSV Inspector: Guide
- Intent
- CSV inspector online for troubleshooting import errors: detect delimiter, count columns, and find broken rows in pasted CSV data (local-only, no uploads).
- What it does
- Bundles three mini tools (column count, delimiter detector, broken-row check) into one UI for fast CSV troubleshooting.
- Key features
- 3 CSV diagnostics in one, Instant results, Local-only processing
- Privacy
- Everything runs locally in your browser. No uploads.
- Best for
- Developers debugging CSV import failures and mysterious parsing errors
- Analysts who received a broken CSV and need a quick sanity check
- Anyone searching 'CSV inspector', 'CSV delimiter detector', or 'CSV broken rows'
- Why this tool
- Three checks in one place so you do not bounce between tools
- Local-only: paste CSV safely without uploading files
- Fast signals (delimiter guess, expected columns, broken rows) before deeper cleanup
How to use
- 1Choose the tool: Column count, Delimiter detector, or Broken CSV check.
- 2Paste your CSV text (header + a few rows is often enough).
- 3Click Analyze CSV to get results.
- 4Switch tools as needed without re-pasting the input.
Common mistakes
- This is a lightweight inspector (it does not fully parse quoted CSV like Excel does).
- Delimiter detection uses only the first line, which may not be representative.
- Column checks assume commas when counting columns and broken rows.
Examples
Quick import troubleshooting
1) Delimiter detector -> guess separator
2) Broken CSV check -> find inconsistent rows
3) Column count -> confirm expected columns
Sanity-check an export
Paste first ~50 lines
Confirm: rows look right and no broken lines.
