Does CSV Inspector upload my data?

Everything runs locally in your browser. No uploads.

How do I use CSV Inspector?

1. Choose the tool: Column count, Delimiter detector, or Broken CSV check. 2. Paste your CSV text (header + a few rows is often enough). 3. Click Analyze CSV to get results. 4. Switch tools as needed without re-pasting the input.

What are common mistakes with CSV Inspector?

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.
