Why use an SQL Formatter?
SQL queries written by developers or generated by ORMs are often hard to read, with inconsistent indentation and casing. A SQL formatter transforms messy queries into clean, well-organized code that's easy to understand, review, and debug. Proper formatting also helps identify syntax errors and improves collaboration among team members.

Technical Details
Our SQL formatter tokenizes the input query and identifies major SQL clauses (SELECT, FROM, WHERE, JOIN, GROUP BY, ORDER BY, etc.) to apply proper line breaks and indentation. Keywords are optionally uppercased for convention compliance. The formatter handles nested queries, subqueries, and common SQL syntax patterns.
FAQ
Which SQL dialects are supported?
The formatter supports standard SQL syntax used by most databases including MySQL, PostgreSQL, SQLite, SQL Server, and Oracle. Database-specific syntax may not format perfectly.
Does the formatter validate SQL syntax?
The formatter performs basic formatting based on keyword recognition. It does not validate SQL syntax or execute queries. Always test formatted SQL in your database before use.
