SQL Formatter & Beautifier
Turn unreadable, single-line SQL queries into clean, professionally formatted database statements.
How to Use SQL Formatter
- Paste your raw or minified SQL query into the text area.
- Click 'Format SQL' to beautify or 'Minify SQL' to strip comments and spaces.
- Review the cleanly indented query with capitalized SQL keywords.
- Copy the formatted SQL query for your database client or code editor.
Technical Specifications & How It Works
Complex SQL queries involving multiple joins, subqueries, and aggregate conditions quickly become difficult to maintain without consistent indentation.
This formatter standardizes SQL dialect keywords (SELECT, FROM, WHERE, JOIN, GROUP BY, ORDER BY) into uppercase and indents nested clauses.
Database credentials, query parameters, and schema structures remain 100% private since no network traffic is generated.
