FAQ

Does this formatter validate my SQL?

No — this is a formatter, not a validator. It restructures whitespace and capitalization but doesn't check syntax correctness. If your SQL has errors, they'll still be in the formatted output.

Does it support database-specific syntax?

The formatter handles standard SQL (ANSI) syntax well. It works with MySQL, PostgreSQL, SQLite, SQL Server, and Oracle queries for standard clauses. Very database-specific syntax may not format perfectly but won't be altered destructively.

Is my SQL sent to a server?

No. All formatting is done entirely in your browser using JavaScript. Your SQL never leaves your device. This is especially important when working with queries containing sensitive data.
