Format and beautify SQL queries across major dialects.
Paste a query above, pick your dialect, and format it into clean, readable SQL with consistent indentation and keyword casing. It supports PostgreSQL, MySQL, MariaDB, SQLite, SQL Server (T-SQL), Oracle PL/SQL, BigQuery, Redshift, and Snowflake, so it understands each one’s syntax rather than applying generic rules.
Formatting runs entirely in your browser — nothing is sent to a server, which matters when a query embeds table or column names you would rather keep private. Use it to make a hand-written query reviewable, or to tidy machine-generated SQL before committing it.
It supports standard SQL plus PostgreSQL, MySQL, MariaDB, SQLite, SQL Server (T-SQL), Oracle PL/SQL, BigQuery, Redshift, and Snowflake. Choosing the right dialect matters because each has its own keywords and quoting rules the formatter respects.
No. Formatting only changes whitespace and keyword casing — it never rewrites logic, reorders clauses, or alters identifiers. The query you get back is semantically identical to the one you pasted, just easier to read.
