Format SQL Queries Instantly

Writing clean, readable SQL is essential for maintaining database code. This free SQL formatter takes your compact or messy queries and restructures them with uppercase keywords, newlines for each major clause, and consistent indentation. Everything runs in your browser — your queries never leave your device, making it safe for production SQL.

What Gets Formatted

The formatter recognises over 30 SQL keywords including SELECT, FROM, WHERE, JOIN variants, GROUP BY, ORDER BY, HAVING, LIMIT, UNION, and subquery constructs. Each keyword starts on a new line, and JOIN/AND/OR clauses are indented for clarity. String literals and quoted identifiers are preserved without modification. For formatting JSON data alongside your SQL, try our JSON formatter.

Minification

The Minify button does the opposite — it strips all unnecessary whitespace and newlines, producing a single-line query. This is useful when embedding SQL in application code, logging, or reducing payload size. You can also use our CSS minifier for stylesheet compression.

SQL Best Practices

Always use uppercase for SQL keywords to distinguish them from table and column names. Indent JOIN clauses and subqueries for visual hierarchy. Add comments for complex logic. Use aliases consistently. This formatter helps enforce these conventions automatically, saving you time during code review.

Frequently Asked Questions

What SQL keywords does the formatter uppercase?

The formatter uppercases common SQL keywords including SELECT, FROM, WHERE, JOIN, LEFT JOIN, RIGHT JOIN, INNER JOIN, OUTER JOIN, ON, AND, OR, ORDER BY, GROUP BY, HAVING, LIMIT, INSERT, UPDATE, DELETE, CREATE, ALTER, DROP, SET, VALUES, INTO, AS, DISTINCT, UNION, CASE, WHEN, THEN, ELSE, END, and more.

Does the formatter support all SQL dialects?

Can I minify SQL as well?

Yes. Click the Minify button to collapse your SQL into a single line with minimal whitespace, which is useful for embedding in code or reducing query size.
