Free Online SQL Formatter
Paste any messy or minified SQL and get a clean, consistently indented query in one click. The formatter understands the structure of common SQL: it breaks SELECT lists onto separate lines, aligns JOINs, indents subqueries and CASE expressions, and puts each major clause (WHERE, GROUP BY, ORDER BY, LIMIT, …) on its own line — while preserving string literals and comments exactly.
Why format SQL?
Readable SQL is debuggable SQL. Well-formatted queries are easier to review in code reviews, easier to spot mistakes in join logic, and much easier to share in documentation or tickets. If you inherit a 300-line one-liner, this tool turns it into something a human can actually reason about.
SQL Formatter FAQ
Which SQL dialects are supported? The formatter is dialect-agnostic for common syntax: Postgres, MySQL, SQLite, SQL Server, and BigQuery all work for standard queries. Is my query sent anywhere? No — formatting runs entirely in your browser. Does it change my query's meaning? No — whitespace is insignificant in SQL, so reformatting never alters execution or results.
