SQL Formatter Online

Instantly beautify, indent, and format SQL queries in your browser. Free, fast, no signup required.

How to Use the SQL Formatter

Paste your raw or minified SQL into the input field and click Format / Beautify. The tool adds proper line breaks before each major clause (SELECT, FROM, WHERE, JOIN, etc.) and indents sub-clauses for readability. Use Minify to compress it back to a single line.

Supported SQL Clauses

SELECT, FROM, WHERE, JOIN (LEFT, RIGHT, INNER, FULL), ON, GROUP BY, ORDER BY, HAVING, LIMIT, OFFSET, UNION, INSERT INTO, VALUES, UPDATE, SET, DELETE FROM, CREATE TABLE, ALTER TABLE.

Common Use Cases

• Readability — format auto-generated or minified queries before reviewing them.

• Code review — share well-formatted SQL in PRs and documentation.

• Debugging — indent complex nested queries to spot logic errors.
