What Is a SQL Formatter?

A SQL Formatter is a tool that restructures raw SQL queries into a clean, human-readable format. It applies consistent indentation, line breaks, and keyword casing, making SQL statements easier to understand and maintain. This is especially useful when working with complex queries containing joins, subqueries, conditions, and aggregations.

Well-formatted SQL improves collaboration between developers, simplifies code reviews, and reduces errors caused by misunderstood query logic. Professional teams often follow SQL formatting standards to maintain consistent database code across projects.
