SQL Formatter — Complete Guide
Raw SQL queries — especially those generated by ORM tools, copied from documentation, or written quickly without formatting — are often hard to read. Long JOIN chains, nested subqueries, and WHERE clauses with multiple conditions become much clearer when properly formatted with consistent indentation and line breaks.
This tool reformats SQL queries into a clean, readable layout with keywords capitalized, clauses on separate lines, and nested expressions properly indented.

- Making auto-generated ORM queries readable for debugging
- Cleaning up SQL before adding to documentation or sharing with colleagues

Tips for best results

Complex subqueries benefit most from formatting — it becomes clear which part of the query is the subquery and which is the outer query
Formatting does not change what a query does — only how it looks

Frequently asked questions
Does formatting change the behavior of my SQL query?
No. SQL ignores whitespace and case in keywords. Formatting only affects readability.
Can this tool format stored procedures and functions?
Basic formatting works for most standard SQL including stored procedures. Very complex procedural SQL with many control flow statements may not be formatted perfectly.
