What does a SQL formatter do?

It rewrites SQL with consistent spacing, line breaks and indentation, and uppercases keywords such as SELECT, FROM and WHERE so the query is easier to read.

Is my SQL sent to a server?

No. Formatting runs entirely in your browser, so your queries stay on your device.

Does formatting change how my query runs?

No. Formatting only changes whitespace and keyword casing, never the meaning of the query.

SQL Formatter — Turn Messy Queries Into Readable Code

A long, single-line SQL query is hard to read and even harder to debug. This free SQL formatter instantly rewrites it with clear line breaks, consistent indentation and uppercase keywords, so the structure of your SELECT, JOIN, WHERE and GROUP BY clauses jumps out.

Need the opposite? The Minify button compresses a query back to a single line for pasting into a terminal, a log or an ORM. Both actions happen entirely in your browser, so no query ever leaves your machine.

How it works

Paste or type your SQL, then tap Beautify. The tool uppercases SQL keywords and breaks the query onto separate lines at the main clauses. Tap Minify to strip all unnecessary whitespace into one compact line, and Copy to put the result on your clipboard.

Frequently asked questions

Which SQL dialects are supported?
The formatter handles common keywords used by MySQL, PostgreSQL, SQLite and SQL Server. It works best on standard SELECT, INSERT, UPDATE and DELETE statements.

Does formatting change my query?
No. Only whitespace and keyword casing change; the logic of the query is untouched.

Will comments be preserved?
Line comments starting with two dashes are kept when beautifying. Inline comments may be moved to the same line as their clause.
