FAQ

Is this a Notepad++ plugin?

No—this is an online formatter. Paste CSV in, format, then paste the result into Notepad++.

Will “Aligned view” keep my output as valid CSV?

Not necessarily. Aligned view is for readability; use “Normalized CSV” (strict) or “TSV” for data you’ll import elsewhere.

Does it handle commas and quotes inside fields?

Yes. It parses double-quoted fields and uses CSV escaping ("" for a literal quote) when normalizing.

How does delimiter auto-detect work?

It samples lines and chooses the delimiter (comma/semicolon/tab/pipe) that produces the most consistent column splits outside quotes.

Why do I see “ragged rows” in the stats?

Your file has lines with different column counts. Enable “Pad ragged rows” for aligned/Markdown output to keep columns lined up.

How do I convert CSV to TSV for Notepad++?

Select “TSV” as the output format and click Format. The output will use tab separators.

Is my CSV uploaded to a server?

No. Formatting runs locally in your browser, and the tool does not make network requests.
