Frequently asked questions

Does DataPorter upload my data to a server?

No. Every conversion runs entirely in your browser using JavaScript. Nothing you paste is sent over the network, logged, or stored anywhere.

Is DataPorter free to use?

Yes — no signup, no usage limits, and no watermarks on the output files.

What file formats can DataPorter convert between?

SQL to CSV, MongoDB to CSV, SQLite to CSV, PostgreSQL to CSV, CSV to SQL INSERT statements, YAML to TOML, and JSON to TypeScript interfaces.

Can DataPorter handle large files?

Since conversion happens in your browser's memory instead of on a server, performance depends on your device. Files up to a few tens of thousands of rows typically convert instantly; very large files may slow down the tab.
