SQL Formatter API
Format, beautify and minify SQL across 15+ dialects. Pass a query and get it pretty-printed with consistent indentation and keyword casing — for PostgreSQL, MySQL, MariaDB, SQLite, SQL Server (T-SQL), Oracle (PL/SQL), BigQuery, Snowflake, Redshift, Spark, Trino, DuckDB, ClickHouse, DB2, Hive and standard SQL. Control the indent width and whether keywords are upper-cased, lower-cased or left as-is. A minify endpoint collapses a query to a single line (stripping comments while preserving string literals), and a dialects endpoint lists everything supported. Pure local processing — no key, no third-party service, instant. Live. 4 endpoints. Built for SQL editors and IDEs, query loggers, migration tooling, documentation and code review.
