SQL Formatter & Beautifier — Format Queries Free, No Login

Paste your SQL — whether it's a single-line minified query or a messy mix of capitalisation and inconsistent indentation — and hit Format. The output is properly indented with keywords uppercased and clauses on their own lines so you can actually read it.

When you're debugging a generated query from an ORM or a stored procedure dumped from a database, it usually comes out as one long line. Trying to spot a missing join or a wrong WHERE condition in 400 characters of flat text is painful. Format it first, then read it.

Formatted SQL also makes code review significantly easier. A well-indented query makes the structure immediately visible — which tables are joined, which conditions apply to which subquery, where the aggregations are.

• Keywords uppercased — SELECT, FROM, WHERE, JOIN, GROUP BY, ORDER BY
• Each major clause on its own line — makes the query structure scannable
• Consistent indentation for nested subqueries and CTEs
• Comma placement follows a consistent style throughout

SQL formatting is part of every database-driven development workflow. Use the SQL cheat sheet alongside the formatter — look up the right syntax, then format your query cleanly before running it. When your queries return JSON columns or JSON functions like JSON_EXTRACT, our JSON formatter validates and prettifies those JSON values. The regex tester is useful for writing patterns to validate or transform column values, and for building REGEXP clauses in MySQL or PostgreSQL queries.

For safely passing query parameters through web requests, our URL encoder percent-encodes values that will be appended to URLs, and our Base64 encoder handles binary column data. When comparing query outputs or reviewing schema migrations, our diff checker shows exactly what changed between two SQL script versions. Our UUID generator creates primary key values for INSERT statements when your schema uses UUID columns. The API response simulator helps test the API layer that queries your database. For building documentation around your schema, our Markdown preview renders your database documentation files.
