SQL Formatter by Dialect

Format SQL queries with configurable indentation, keyword casing, and commas, for standard SQL, PostgreSQL, MySQL, SQLite, and SQL Server, preserving strings, quoted identifiers, comments, and parameters. It never runs the query, never connects to a database, and never validates its semantic correctness or claims it's optimized — it only reformats the text.

Frequently asked questions

Does it run the query or connect to a database?
No, never. It only tokenizes and reformats the SQL text; it doesn't run anything or connect to any database server.
Does it confirm the query is correct or optimal?
No. Formatting the text correctly doesn't mean the query is semantically correct, safe, or optimized; this tool doesn't analyze that.
