  3. 3Click 'Format' — the query is re-indented with keywords capitalized and structure clarified.

Frequently Asked Questions (FAQ)

Which SQL dialects are supported?

MySQL, PostgreSQL, SQLite, T-SQL (SQL Server), and standard SQL are all supported.

Will formatting change my query's behavior?

No. Formatting only affects whitespace and capitalization — the query's logic and output remain identical.

Can I format very long queries?

Yes. There's no size limit since everything runs locally. Large queries may take a moment to format.

Zero Data Leaks
