SQL Formatter
Pretty-print and indent SQL queries for MySQL, PostgreSQL, SQLite, T-SQL and standard SQL.
Paste a cramped or auto-generated SQL query and get it reformatted with consistent indentation, capitalized keywords, and clean line breaks around clauses like SELECT, JOIN, and WHERE. Supports dialect-aware formatting for MySQL, PostgreSQL, SQLite, T-SQL, and standard SQL, which matters for quoting and dialect-specific syntax. Useful for cleaning up a query pulled from application logs or a database GUI before sharing it in a code review. Formatting runs entirely in your browser.
Runs on your device. This tool processes your file inside this browser tab. Nothing is uploaded, so it also works offline once the page has loaded, and closing the tab discards the file from memory.

Common questions
Does it validate my SQL?
It formats syntax it recognizes; it isn't a full SQL parser or validator.
Does it upload my queries?
No - formatting runs entirely in your browser.
Which SQL dialects are supported?
MySQL, PostgreSQL, SQLite, T-SQL, and standard SQL formatting rules are all available as options.
Does it reformat stored procedures or scripts?
It's built for formatting individual queries and statements; very large multi-statement scripts may format less predictably.
