Key Features
Private
Schema, table names, and query logic never leave your browser.
Structured Output
Keywords are uppercased; each clause (FROM, WHERE, JOIN) starts on its own line.
Instant
Format any query — simple SELECT or complex multi-JOIN — in milliseconds.
Pro Tips
Formatted SQL is much easier to review in pull requests — consider formatting SQL in your codebase consistently.
CTEs (WITH clauses) format particularly well — each CTE on its own indented block makes complex queries readable.
For SQL linting (checking for anti-patterns like SELECT * or missing WHERE on DELETE), use SQLFluff — formatting is just the first step.
