SQL Formatter – Clean and Format SQL Queries for Readability
The SQL formatter transforms messy or compressed SQL queries into clean, indented, readable format. Paste your SQL query and get an instantly formatted version.
The tool supports MySQL, PostgreSQL, SQLite, and Microsoft SQL Server syntax. You can also minify queries for production use or convert to uppercase keywords (SELECT, FROM, WHERE, etc.).
Why is SQL query formatting important?
Well-formatted SQL is easier to read, debug, and maintain. Long queries without indentation quickly become incomprehensible. Standard practice: keywords in uppercase, each clause on its own line, indentation for subclauses. The SQL formatter does this with one click.
