Does it support different SQL dialects?

It formats standard SQL syntax that's broadly compatible across common databases — dialect-specific keywords still format correctly as part of the general structure.

Will formatting change how the query actually executes?

No, formatting only changes whitespace, indentation and capitalization — the query's logic and execution are completely unaffected.

Can it handle complex queries with multiple joins and subqueries?

Yes, it's built to handle realistic, complex queries, not just simple single-table selects.

Does SQL Formatter upload my files to a server?

No. SQL Formatter runs entirely in your browser using on-device processing, your files never leave your device.

About this tool

A dense, unformatted SQL query — especially one with several joins and subqueries — is much harder to read, debug or hand off to a teammate than the same query properly indented and capitalized. This tool formats and beautifies SQL queries for readability, turning a wall of SQL into something that's actually easy to scan and understand.
