SQL Formatter
Format and validate SQL queries across dialects
SQL Formatter: Beautify, Indent & Format SQL Queries Online
Dense, single-line SQL queries are taken by this formatter and proper indentation, keyword casing, and line breaks are added so the logic is easy to follow. MySQL, PostgreSQL, SQLite, and MSSQL dialects are all supported. Especially helpful when complex queries with multiple joins, subqueries, or CTEs are reviewed after being written as one-liners. SQL can also be linted and minified using this tool.
Multiple dialect support
SQL isn't one language — it's a family. MySQL, PostgreSQL, SQLite, and MSSQL all have slightly different syntax. These differences are understood and appropriate formatting rules are applied for each specific dialect, including proper keyword capitalization and function formatting.
When should SQL be minified?
Minification removes comments and whitespace from SQL, making it smaller for storage in config files or embedding in application code. The query logic isn't changed — it's just compressed into a single line. Useful when queries need to be stored in JSON or passed as URL parameters.
