Frequently asked questions

Which SQL dialects are supported?+

Standard SQL plus PostgreSQL, MySQL, MariaDB, SQLite, SQL Server (T-SQL), Oracle (PL/SQL), BigQuery, Snowflake, Redshift and Spark SQL. Pick the one closest to your database for the most accurate formatting.

Does it change what my query does?+

No. It only reformats whitespace, indentation and keyword case — the query logic and identifiers are left exactly as written.

Can I keep my keyword casing?+

Yes. Choose UPPER, lower or Preserve. Preserve leaves SELECT/select exactly as you typed it.

Is my SQL uploaded?+

No. Formatting runs entirely in your browser; your SQL never leaves your device.
