SQL Formatter

The SQL Formatter beautifies or minifies queries with consistent indentation and keyword casing, and it supports several dialects including MySQL, PostgreSQL, SQL Server and SQLite. Syntax highlighting makes long, deeply nested statements far easier to read, review and reason about than a single unbroken line of text.

Developers and data analysts use it to clean up generated or hand-written SQL before sharing it in a pull request, in documentation or on a support ticket. While the formatter improves structure and surfaces obvious formatting problems, queries should still be run and validated against your actual database engine before you depend on them.

Formatting runs entirely in your browser, so the queries you paste — which can reveal table names and schema details — are never uploaded to a server. There is no install and no account, which keeps the tool fast and your database structure private. You can format queries from production systems without any of those details being uploaded or retained anywhere.
