About this tool
Long queries written under deadline pressure — or generated by an ORM and pulled out of a log — are hard to reason about until the clauses line up. This tool re-indents SQL with consistent keyword casing and clause breaks, so joins and predicates become scannable.
Several dialects are supported, because formatting rules differ: PostgreSQL, MySQL, SQLite, MariaDB, BigQuery, Snowflake, Transact-SQL and standard SQL. Pick the one your database actually speaks for the most faithful result.
How to use it
- 1Paste your query into the input panel.
- 2Select the SQL dialect and keyword casing.
- 3Copy the formatted query back into your editor.
