Why Format SQL Queries?
Unformatted SQL is notoriously hard to read and debug. A 500-character query written as a single line with no spacing is nearly impossible to follow — especially when tracking down a logic error in a complex JOIN chain. Proper SQL formatting separates clauses onto new lines, indents subqueries, and aligns keywords so the logical structure of the query is immediately obvious.
Formatted SQL is also much easier to review in code reviews, add to documentation, or share with colleagues who need to understand your data logic.
Before and After: select u.id,u.name,o.total from users u inner join orders o on u.id=o.user_id where o.total>100 order by o.total desc becomes a 10-line beautifully structured query with each clause on its own line.

Formatting Style Options
- Keyword case: UPPERCASE (SELECT, FROM, WHERE) or lowercase — choose your team's convention
- Indent style: 2 or 4 spaces, or tab indentation
- Comma position: End of line (standard) or beginning of line (some prefer this for comment-out ease)
- Clause placement: Each major clause (SELECT, FROM, WHERE, ORDER BY) on its own line

Format SQL NowSQL Minification — When You Need It
The opposite of formatting — SQL minification removes all whitespace and compresses a query to a single line. Useful when embedding SQL in code strings, config files, or when you need to reduce payload size in API calls that pass SQL queries. Switch to Minify mode to do this in one click.
Core SQL Formatting Rules
- Each major clause (SELECT, FROM, WHERE, GROUP BY, ORDER BY, HAVING) starts on a new line
- JOIN conditions are indented under their JOIN keyword
- Subqueries are indented relative to the enclosing query
- CTE (WITH) blocks each get their own clearly separated section
- Long SELECT lists wrap with each column on its own line
