What is this tool

This SQL Formatter is a dialect-aware SQL beautifier and analyzer that runs entirely in your browser. It cleans indentation, normalizes spacing, and adjusts keyword casing while respecting MySQL, PostgreSQL, MSSQL, SQLite, or generic SQL styles. The built-in analyzer reports query type, table and join counts, WHERE conditions, aggregation functions, and whether GROUP BY, ORDER BY, or subqueries appear.

Use it to format SQL online before code review, tidy generated queries, or minify SQL for embedding. Because nothing is uploaded, it is safe for migrations, production snippets, analytics dashboards, or ad-hoc data fixes. The tool keeps comments intact and offers Readable, Compact, and One-line modes so you can choose between review-friendly or share-friendly output.

This tool only formats text. It does not execute or validate SQL against a database. Keep your queries private while improving clarity for teammates and future you.
