Well-formatted SQL is easier to read, review, and debug. This SQL formatter takes messy or minified SQL queries and applies consistent formatting: keywords are uppercased, major clauses start on new lines, and subqueries are indented for clarity.
The output includes syntax highlighting with keywords in blue, string literals in green, and numbers in orange. This visual differentiation makes it faster to scan queries and spot errors, especially in complex joins and nested subqueries.
The formatter recognizes standard SQL keywords including SELECT, FROM, WHERE, JOIN, GROUP BY, ORDER BY, HAVING, INSERT, UPDATE, DELETE, CREATE, ALTER, DROP, and many more. All processing happens in your browser with no server communication.
