SQL Formatter

Format and beautify SQL queries

About SQL Formatter

SQL Formatter breaks a fixed list of SQL keywords (SELECT, FROM, WHERE, JOIN, and about 20 others) onto new lines and adds a line break after every comma, entirely in your browser — nothing is uploaded to a server. It's a simple keyword-matching pass, not a real SQL parser, but it is string-aware: string literals ('...') and double-quoted identifiers, including ones with a doubled-quote escape like 'it''s', are scanned separately from the surrounding SQL, so a keyword or comma inside one is copied through untouched instead of getting an unwanted line break.

How to use SQL Formatter

  1. 1Paste your SQL query into the input box.
  2. 2Click 'Format' to break keywords and comma-separated items onto new lines.
  3. 3Review the result in the output box.
  4. 4Click 'Copy' to copy the formatted SQL to your clipboard.

Frequently Asked Questions

Is SQL Formatter free to use?

Yes, it's completely free with no signup required.

What SQL dialects does it support?

It matches a fixed list of common keywords (SELECT, FROM, WHERE, JOIN, GROUP BY, and similar) that are shared across most SQL dialects, but it doesn't parse or validate dialect-specific syntax.

Can I customize indentation size or keyword case?

No, there are no formatting options — the line-break behavior and spacing are fixed.

Is my SQL uploaded to a server?

No, formatting happens entirely in your browser.

Tips & Tricks

  • ✓String literals and quoted identifiers, including ones with an escaped quote (e.g. 'it''s'), are scanned as protected content, so a keyword or comma inside them won't get an unwanted line break.
  • ✓This is a lightweight readability pass, not a validator — it won't catch syntax errors in your SQL.
  • ✓For dialect-specific formatting or full SQL parsing, use a dedicated SQL formatting library instead.
  • ✓Review the formatted output before running it — this is a readability pass, not a validator, so it won't catch typos or invalid syntax in your original query.
