What SQL Formatter does
Readable SQL makes joins, filters, grouping, and nested expressions easier to review. The formatter tokenizes common SQL syntax while preserving quoted strings and comments, and can also create a compact transport-friendly form.
Common uses
- Beautify SQL copied from logs
- Normalize keyword case for reviews
- Minify a query for configuration or debugging
Privacy and limitations
SQL text is formatted entirely in the browser. The tool never connects to a database or executes the query.
Validate important output in the actual language, database, or target platform.
Frequently asked questions
Does this execute SQL?
No. It only transforms text and cannot connect to a database.
Are all dialect features supported?
Common MySQL, PostgreSQL, SQLite, and SQL Server statements are formatted. Vendor-specific procedural syntax may need the database vendor's formatter.
Can formatting change query behavior?
The formatter preserves tokens and quoted content, but important production SQL should always be reviewed and tested against the target database.
