SQL Formatter
Beautify messy SQL queries into readable statements.
Long SQL statements written on a single line — or generated by an ORM — are painful to review.
About SQL Formatter
Turn dense, single-line SQL into cleanly indented, readable statements with proper keyword casing and line breaks. This free SQL formatter and beautifier supports common dialects and is handy for reviewing query logs, cleaning up ORM-generated SQL, or preparing queries to share in a pull request or documentation.
Long SQL statements written on a single line — or generated by an ORM — are painful to review. This SQL formatter breaks a query into logical clauses, indents subqueries and joins, and normalises keyword casing so SELECT, FROM, WHERE and GROUP BY line up and the query's structure becomes obvious. It supports standard SQL along with popular dialects, and everything runs locally in your browser.
