SQL Formatter

What is SQL Formatter?

A SQL formatter transforms raw, single-line SQL queries into cleanly formatted statements with proper indentation, line breaks at clause boundaries (SELECT, FROM, WHERE, JOIN, etc.), and standardized keyword casing. Well-formatted SQL is dramatically easier to read, debug, and review than single-line queries. The formatter applies industry-standard formatting conventions: major clauses start on new lines, JOIN conditions are indented, AND/OR conditions are clearly separated, and keywords are uppercased for visual distinction from table/column names. This tool supports all standard SQL syntax including SELECT, INSERT, UPDATE, DELETE, CREATE, ALTER, subqueries, and Common Table Expressions (CTEs).

How to Use SQL Formatter

1. Paste your SQL query.
2. Click Format SQL.
3. View the formatted output with proper indentation.
4. Keywords are automatically uppercased.

Examples

select u.name, u.email from users u inner join orders o on u.id = o.user_id where o.total > 100 order by o.total desc

Common Use Cases

• Formatting complex SQL queries for code review
