A layout pass, not a parser: it never changes what the query does, and strings, quoted identifiers and comments are left exactly as written. It reads MySQL, PostgreSQL and SQLite alike.

Runs in this browser. Nothing you paste is sent to a server.

About this tool

Method, assumptions, practical next steps, and limits.

Format before you read a plan

An ORM's query log prints SQL on one line. Formatting it is the first step before running EXPLAIN, because the join order, the conditions and the subqueries become visible at a glance. Laravel's DB::listen() or ->toRawSql() (Laravel 10.15+) give you the query with its bindings filled in.

What it does not do

This is a layout pass rather than a parser, so it never changes what the query does and never rejects one. It also cannot tell you a query is wrong: check it against the database with EXPLAIN before trusting it.

Frequently asked questions

Does formatting change my query?

No. Only whitespace and, if chosen, keyword case change. Strings, identifiers and comments are left exactly as written.

Which databases does it support?

MySQL, MariaDB, PostgreSQL and SQLite syntax all format the same way, including backtick and double-quote identifiers.

Is what I paste sent anywhere?

No. The tool runs entirely in your browser with JavaScript. Nothing you type or paste is sent to our server or stored.
