Format SQL queries online

SQL Tools takes messy, single-line SQL and turns it into clean, properly indented queries — with support for MySQL, PostgreSQL, SQLite, and more.

Why use this tool

Multiple dialects

Format for Standard SQL, MySQL, PostgreSQL, SQLite, or MariaDB — each with dialect-accurate keyword and syntax handling.

Readable indentation

Clauses like SELECT, FROM, WHERE, JOIN, and GROUP BY are broken onto their own lines with consistent indentation.

Upper-cased keywords

SQL keywords are automatically capitalized for a clean, consistent style across your codebase.

Private and offline

Your queries never leave your browser.
