SQL Formatter

Format, minify, and validate SQL queries

Paste a cramped or one-line SQL query and get it formatted with consistent keyword casing, indentation, and line breaks that make complex joins and subqueries readable. You can also minify queries for embedding. It supports the SQL you write every day, helping with code review and debugging.

Frequently asked questions

Does formatting change what my query does?

No. Formatting only adjusts whitespace, casing, and line breaks for readability. The query's logic and results are unchanged.

Which SQL dialects are supported?

It handles standard SQL constructs used across popular databases, so the common SELECT, JOIN, WHERE, and CTE syntax formats cleanly.

Can it format a long query with many joins?

Yes. That's where it helps most: nested subqueries and multi-table joins become far easier to scan once indented consistently.
