Beautify and format SQL queries with consistent indentation and keyword casing.
Paste or type your input here, SQL Formatter is loading…
SQL Formatter turns messy, minified, or inconsistently styled SQL into clean, indented, readable queries. It re-aligns clauses, normalises keyword casing, and lays out joins and subqueries so a complex statement becomes easy to scan, review, and debug.
Crucially, it changes only presentation, never logic. Whitespace, indentation, and casing are adjusted; tables, columns, conditions, and the result of the query stay exactly the same. That makes it safe to run on anything from a quick ad-hoc query to a full migration script.
Everything happens in your browser, so your SQL, which often exposes schema details and sometimes data, never leaves your device. That privacy matters when you're working with production queries you wouldn't want to paste into a server-side service.
Formatting consistently pays off in code review and version control: clean, aligned SQL produces smaller, clearer diffs and makes logic mistakes easier to catch. Pair it with the JSON Formatter and other ToolsMonk developer tools to keep your whole stack tidy.
