Is my CSV uploaded to Convertr?

No. The CSV formatter runs entirely in your browser. Your pasted data and local files are not uploaded to Convertr servers.

What CSV errors does this validator detect?

It detects unclosed quoted fields and rows with a different number of columns than the header or first data row.

कौन से डेलिमिटर समर्थित हैं?

The tool supports commas, semicolons, tabs and pipes. Auto-detect chooses the delimiter that creates the most consistent rows.

Can I use this as a CSV viewer?

Yes. Parsed rows are shown in a table preview so you can inspect columns before copying or downloading the cleaned output.
