SQL Formatter
Runs entirely in your browser
Beautify SQL queries directly in your browser. This only rewrites text — it never executes your SQL.
What is SQL Formatter?
SQL Formatter rewrites a SQL query onto multiple readable lines — one clause per line, comma-separated columns indented underneath SELECT, and keywords uppercased — without changing what the query does. It's purely a text transformation and never connects to a database.
How to use SQL Formatter
- Paste your SQL query into the Input box.
- Click Format.
- Copy the readable result from the Output box.
Features
- Supports SELECT, INSERT, UPDATE, DELETE, JOINs, WHERE, GROUP BY, ORDER BY, HAVING, LIMIT and CASE.
- Uppercases SQL keywords for readability.
- Preserves string literals and comments exactly.
- Never executes or connects to a database — text in, text out.
- 100% client-side — your SQL never leaves your browser.
Frequently Asked Questions
Does this execute my SQL?
No. This tool only rewrites the text of your query for readability. It never connects to a database or executes anything.
Is my SQL uploaded to a server?
No. Formatting happens entirely in your browser.
Which SQL dialects does this support?
It formats common ANSI SQL syntax — SELECT, INSERT, UPDATE, DELETE, JOINs, WHERE, GROUP BY, ORDER BY, HAVING, LIMIT and CASE — used across MySQL, PostgreSQL, SQL Server and SQLite. It's a text-based formatter, not a full SQL parser, so highly unusual or vendor-specific syntax may not format perfectly.
Will formatting change what my query does?
No. Only whitespace, line breaks and keyword casing change — every identifier, literal and operator is preserved exactly.
