How it works
1. Paste your CSV
Drop in an Excel export, a database dump, or any RFC 4180 CSV. Click Load sample to see an example.
2. We parse and structure
Quoted fields, embedded commas, and escaped quotes are all handled. Columns with dots (user.email) become nested objects.
3. Copy or download
Click Copy JSON for clipboard, or Download .json for a file. Everything happens locally in your browser.
Why use this converter
- Private by design. Your CSV never leaves your browser. Nothing uploaded, logged, or stored.
- RFC 4180 compliant. Quoted fields, embedded commas, embedded quotes, CRLF and LF line endings. All handled correctly.
- Nested output via dot columns. A column named
contact.emailbecomes nested JSON under a contact object automatically. - Free forever. No signup, no rate limits, no paywall.
Need more than conversion?
If you find yourself wrangling CSV exports over and over because your team has no central place to capture messy inputs, you might want a proper intake queue. We are building one.
