About SQL Formatter

Complex SQL queries with multiple JOINs, subqueries, and nested conditions are notoriously difficult to read when written on a single line or with inconsistent formatting. Xevon Tools' SQL Formatter applies proper indentation, line breaks, and keyword casing to make the logical structure of any query immediately clear. The formatter supports Standard SQL, PostgreSQL, and MySQL dialects, and uppercases keywords (SELECT, FROM, WHERE, JOIN) following the most common SQL convention. This is invaluable for code reviews, debugging complex queries, cleaning up ORM-generated SQL, and preparing examples for documentation. The tool handles everything from simple SELECTs to complex CTEs and window functions. Everything runs in your browser, so even queries containing sensitive table names or data stay private.

Frequently asked questions

Standard SQL, PostgreSQL, and MySQL dialects are supported. Each dialect applies formatting rules appropriate to its syntax, such as handling double-quoted identifiers in PostgreSQL.

No. The tool formats the query structure without validating syntax. If the SQL contains errors, they will remain in the output but may be easier to spot with proper formatting.
Yes. The formatter handles complex queries with multiple JOINs, subqueries, CTEs, and window functions without issues.
