Free Online SQL Formatter & Beautifier

Paste a query above and click Beautify: keywords are uppercased, each major clause — SELECT, FROM, WHERE, JOIN, GROUP BY, ORDER BY — starts its own line, conditions are indented, and string literals are preserved exactly. Minify collapses a formatted query back to one line for logs or command-line use. Your queries never leave your browser — safe for anything containing table names or data you would not paste into a random website.

Why format SQL?

SQL copied from application logs, ORM debug output or a colleague's message usually arrives as a single dense line. Formatting exposes the query's logic: which tables join to which, where the filters are, what the grouping does. In code review, consistently formatted SQL is dramatically faster to check for bugs like a missing join condition or a filter applied after aggregation instead of before. Our article on SQL formatting best practices covers the conventions used by professional teams.

What the formatter does

• Keyword casing — select becomes SELECT, making structure scannable.
• Clause line breaks — every major clause and each JOIN starts a new line.
• Condition indentation — AND/OR conditions indent under their clause.
• Column lists — comma-separated columns break onto their own lines for easy diffing.
• String safety — anything inside 'single', "double" or `backtick` quotes is never modified, so data values and quoted identifiers stay intact.

Supported dialects

The formatter is dialect-agnostic: it recognises the shared keyword set of MySQL, PostgreSQL, SQL Server, SQLite, Oracle and MariaDB. Dialect-specific syntax it does not recognise simply passes through unchanged rather than being mangled.

Frequently asked questions

Does it execute or check my SQL against a database?

No — it is a text formatter. Validate checks structural balance (parentheses, quotes) but cannot know your schema.

Will it change values inside my strings?

Never. String literals are protected before any transformation runs.

Can it handle multiple statements?

Yes — statements separated by semicolons are formatted in sequence with a blank line between them.
