About This Tool

This free online SQL Formatter helps you clean raw query text into readable structure so reviews and debugging are faster. Paste messy SQL from logs, ORM output, or migration scripts, then format it into consistent lines with clear clause boundaries. It is useful for query optimization sessions, pull-request reviews, and data-team collaboration.

Simple mode gives one-click formatting for quick edits. Advanced mode allows indentation control and keyword casing preferences for teams that follow strict style conventions. Everything runs in-browser and no SQL content is stored on IO Tools servers.
