常见问题

›Which SQL dialects are supported?

Standard ANSI SQL works across PostgreSQL, MySQL, SQLite, MS SQL and most others. Vendor-specific extensions may format imperfectly.

›Does it modify the query?

Only whitespace and case — keywords are uppercased by convention but the logic is identical to your input.

›Is my SQL sent to a server?

No — formatting happens entirely in your browser. Useful when working with sensitive queries.

›Can it format very long queries?

Yes — anything your browser can hold in memory. Multi-thousand-line queries work fine.

›Is the formatter free?

Yes — fully free, no signup.
