SQL Formatter

Paste raw or minified SQL and format it into a readable, indented statement with each major clause on its own line. This is a best-effort, regex-based formatter for readability — not a full SQL parser or validator, so always double-check the output for complex or unusual queries.

How it works

The formatter collapses extra whitespace and then inserts a line break before each major clause keyword — SELECT, FROM, WHERE, JOIN, GROUP BY, ORDER BY, and so on — indenting AND/OR conditions slightly since they usually belong inside a WHERE clause.

Tip

This is a lightweight, best-effort formatter based on keyword matching, not a real SQL parser — it won't validate your syntax or understand nested subqueries perfectly, so always review the result before running it.
