What is SQL Formatter?

A SQL Formatter takes messy or minified SQL queries and reformats them with proper indentation, line breaks, and keyword casing. It makes complex queries readable and maintainable — essential for code reviews, documentation, and debugging.

How to Use SQL Formatter

Paste your SQL query and click Format. Choose indentation size (2 or 4 spaces) and keyword casing (UPPERCASE or lowercase). Use Minify to compress queries for production use. Toggle syntax highlighting for color-coded output.
