SQL Formatter & Beautifier
Format SQL online with readable indentation, configurable keyword casing, and support for popular SQL dialects. Queries are processed in your browser and are never executed.
SQL query formatter
This tool formats SQL text; it does not execute queries or validate them against a database.
How to use this tool
Choose the dialect used by your database, paste a query, and adjust keyword case and indentation before formatting. Review the result in your SQL client because formatting is not syntax validation. Processing happens in your browser; entered values are not sent to a service.
Frequently asked questions
Does the formatter execute SQL or verify syntax?
No. It only rearranges SQL text for readability. It does not connect to a database, execute a query, or provide database-backed syntax validation.
Which SQL dialects can I format?
Choose a dialect from the formatter menu, including PostgreSQL, MySQL, SQLite, SQL Server, BigQuery, Snowflake, and others supported by the formatting library. Dialect support affects formatting; it is not a compatibility check.
Are comments, strings, and quoted identifiers retained?
The formatter recognizes common SQL tokens and keeps string literals, quoted identifiers, and comments while changing whitespace and layout. Review the result before running any query.
