About DataParser Pro
What it does
DataParser Pro is a small, focused browser tool for cleaning up messy data. Paste or drop in a CSV export, a chunk of log output, source code, or loose key:value text, and it auto-detects the format and restructures it into JSON, CSV, or a Markdown table — instantly, with no upload step. It also handles multiple files at once, keeps a short local history of what you've run, and works from either a light or dark theme.
Why it's free to try
Every input gets a full free preview of the first 5 structured rows, so you can see exactly what the tool would produce before paying anything. Unlocking the complete export costs $9 once, or $4.99/month for the Power tier if you regularly need batch processing across multiple files.
Why it's private by default
The parsing itself runs entirely in your browser's JavaScript — there's no server that receives or stores the data you paste in. The only things that leave your device are an optional feedback message and, if you choose to pay, your billing details handled directly by Stripe. See the Privacy Policy for the full picture, including how any advertising on this site works.
Who's behind it
DataParser Pro is built and maintained independently, as a single-purpose utility rather than a large company product. If you'd like it to do something it doesn't yet, the fastest way to reach me is the feedback form on the homepage.
Frequently asked questions
Is my data really not uploaded anywhere?
Correct — the parsing logic runs client-side in your browser. Opening your browser's network inspector while using the tool will show no request carrying your pasted content anywhere.
What formats does it detect?
CSV/TSV and other delimited text, timestamped log lines, source code (with comments split out), simple key: value data, and a plain-text fallback for anything else.
Can I cancel the Power subscription?
Yes, anytime — see the Terms of Service for how.
