SQL Formatter

What is SQL Formatter?

A SQL formatter beautifies raw SQL queries with proper indentation, keyword capitalization, and line breaks. Well-formatted SQL is easier to read, review in pull requests, and debug when queries grow complex with multiple joins and subqueries.

Whether you are writing reports, reviewing database migrations, or learning SQL, a formatter transforms dense single-line queries into a clear, hierarchical structure that highlights clauses and nesting.

Our formatter supports standard SQL syntax including SELECT, INSERT, UPDATE, DELETE, JOINs, subqueries, and common functions. Everything runs in your browser for instant results.
