Unminify SQL

Restore readable formatting via sql-formatter.

Basic example

Minified SQL

SELECT c.id, c.email, o.total, o.created_at FROM customers AS c INNER JOIN orders AS o ON o.customer_id = c.id WHERE c.active = TRUE AND o.status = 'completed' ORDER BY o.created_at DESC LIMIT 50;

Formatted SQL

SELECT c.id, c.email, o.total, o.created_at FROM customers AS c INNER JOIN orders AS o ON o.customer_id = c.id WHERE c.active = TRUE AND o.status = 'completed' ORDER BY o.created_at DESC LIMIT 50;

Options

SQL Dialect
Target dialect for beautify formatting (standard, PostgreSQL, MySQL, SQLite).
Keyword Case
Upper, lower or preserve keyword casing during beautify.
Indent Width
2 or 4 spaces for beautify and unminify output.

Dialect support

Beautify supports standard SQL, PostgreSQL, MySQL and SQLite dialects. Minify uses whitespace stripping — edge cases in T-SQL or BigQuery are out of scope.
