Which SQL dialects are supported?

PostgreSQL, MySQL, SQLite, MariaDB, SingleStoreDB, Spark, Trino, BigQuery, DB2, and standard ANSI SQL.

Does it validate SQL syntax?

No — it formats based on heuristic token patterns, not a full SQL parser. Invalid SQL may still produce formatted output. Use your database client or EXPLAIN for validation.

Common use cases

Formatting minified ORM-generated SQL queries for debugging
Beautifying SQL before committing to version control
Reading and understanding complex multi-join queries
Standardizing SQL style in a team codebase
Formatting queries copied from database error logs

How it works

Uses the sql-formatter library which tokenizes the SQL input and rebuilds it with proper indentation, keyword capitalization, and newlines based on the selected dialect. Keywords like SELECT, FROM, WHERE, JOIN get their own lines; nested clauses are indented; subqueries are formatted recursively.
