SQL Formatter by Igor

Stop reformatting SQL by hand.

SQL Formatter cleans up messy, unformatted SQL into consistent, readable queries — instantly, and entirely inside your browser. Nothing you paste or select is ever sent anywhere.

Two ways to use it:

• Popup formatter — click the extension icon, paste your SQL, pick your dialect, format. Copy the result with one click.

• Right-click anywhere — select SQL text on any webpage and choose "Format SQL" from the right-click menu. In editable fields, it replaces text in-place. Otherwise, formatted SQL is copied to your clipboard.

Supports: Transact-SQL (SQL Server), MySQL, MariaDB, PostgreSQL, SQLite, PL/SQL (Oracle), BigQuery, Snowflake, Redshift, Spark, and standard SQL.

Customize: indent size (2/4 spaces or tabs), keyword casing (UPPERCASE or preserve).

Privacy: 100% local formatting. No network requests, no data collection, nothing tracked.
