Does it validate the SQL?

No — it's a formatter, not a linter. Use your database's EXPLAIN for validation.

Written against ANSI SQL keywords; Postgres, MySQL, and SQLite queries all format correctly.

SQL Formatter

Format a single-line SQL query into readable multi-line SQL.

Formatted

SELECT id,
  name,
  email
FROM users u
JOIN orders o
ON o.user_id = u.id
WHERE u.created_at > '2025-01-01'
AND o.status = 'paid'
ORDER BY u.created_at desc
LIMIT 50

Runs entirely in your browser — nothing you paste is sent to a server.

About this tool

A fast, opinionated formatter for SELECT/INSERT/UPDATE/DELETE queries. Wraps clauses on their own lines, indents projection lists, and uppercases keywords.

How it works

Paste a query — one line or many.
The formatter normalises whitespace and inserts breaks before SQL keywords.
Projection lists split on commas with a 2-space indent.

When to use it

Cleaning up a query pasted from an ORM's log.
Preparing a query for a blog post or slide deck.
Sanity-checking generated SQL from an LLM.
