The SQL formatter tidies and beautifies your SQL queries with clean indentation and uppercase keywords, so they're easy to read, review and maintain. It supports the main dialects — MySQL, PostgreSQL, SQLite, SQL Server and BigQuery — so it works with virtually any database. Paste a long, messy query and get a formatted, readable version instantly, ready to copy into your editor or documentation. Formatting SQL saves time when debugging and reduces errors in complex queries with many JOINs and subqueries. All formatting runs locally in your browser: your queries are never uploaded to any server, so you can format SQL with sensitive data without worrying.

Frequently asked questions

Is my SQL sent to a server?

No. Formatting happens 100% in your browser. Your query never leaves your device, ideal for SQL with sensitive data.

Which dialects are supported?

Standard SQL, MySQL, PostgreSQL, SQLite, Transact-SQL (SQL Server) and BigQuery, each with its syntax particularities.

Does it change my query?

No. It only reorganizes the formatting (spaces, line breaks, uppercase keywords). The query logic is exactly the same.

Does it work for minified one-line SQL?

Yes. It takes any query, whether on one line or unordered, and makes it readable with the correct structure.
