FAQ
Is my SQL uploaded when I format it here?
No. Formatting runs entirely in your browser; your queries are not sent to a server.
Which dialect should I choose (PostgreSQL, MySQL, BigQuery, T-SQL)?
Pick the one closest to your target engine. Dialect-aware formatting handles quoting and syntax differences more reliably.
Will formatting change what my query does?
Formatting should only change whitespace and layout. Still, test the formatted SQL in a safe environment before running it in production.
Can I beautify a large SQL script or dump?
Yes, but very large inputs may be slower depending on your device. If it’s laggy, format smaller sections or remove huge INSERT blocks temporarily.
