SQL Formatter
Format and beautify SQL queries instantly. Supports MySQL, PostgreSQL, SQL Server, and Oracle. All processing runs in your browser — no data sent anywhere.
Tips for Formatting SQL
Get readable queries that your team will thank you for:
- Format Before Debugging: A messy one-line SQL query is nearly impossible to reason about. Paste it here and format first — the structure reveals missing joins, broken conditions, and logic errors that are invisible in minified code.
- Choose Your Indent Width Thoughtfully: 2 spaces keeps deeply nested subqueries from running off the screen. 4 spaces makes the structure more obvious at a glance. Pick one and stick with it across your team.
- Uppercase Keywords for Scanability: When
SELECT, FROM, WHERE, and JOIN are uppercased, your eye can jump directly to each clause. Use the "Uppercase" button after formatting to apply this convention.
- Minify for Embedding: Need to embed a query in application code as a string? Format it first for readability during development, then use the "Minify" button to produce the compact version that goes into your source file.
Why Format SQL
A well-formatted query isn't just aesthetic — it directly impacts your productivity:
- Debugging speed: A formatted query exposes missing join conditions, incorrect GROUP BY clauses, and unbalanced parentheses instantly. You'll spot bugs in seconds that would take minutes in a tangled one-liner.
- Code review: Reviewers can follow the logic of a formatted query. A minified 300-character SELECT is almost guaranteed to get a "please reformat" comment.
- Refactoring: Need to add a new column or change a join type? Consistent formatting means you can locate the right clause without scanning the entire query.
- Portability: The formatter normalizes dialect quirks into consistent structure, making it easier to port a query from MySQL to PostgreSQL or vice versa.
