A SQL query pasted from a log file or minified application code is often a single dense line that's hard to read or debug. This SQL formatter parses your query and reformats it with consistent indentation and standardized keyword capitalization, so clauses like SELECT, FROM, WHERE, and JOIN are clearly separated and easy to scan. It's built for developers reviewing queries in code review, DBAs auditing slow query logs, and anyone learning SQL who benefits from seeing well-structured examples. The formatter handles common SQL dialects including standard clauses, subqueries, and joins without altering the query's actual logic. Since formatting happens entirely in your browser, your query is never uploaded to a server, and there's no signup required. Paste your SQL below to see it beautifully formatted instantly.

Frequently asked questions
What does a SQL formatter do?
It rewrites a dense or inconsistently formatted SQL query with clear indentation and standardized keyword capitalization, making the query structure easy to read.
Does formatting change what the query does?
No, only whitespace, line breaks, and keyword casing are adjusted - the actual logic and execution behavior of the query remain unchanged.
Can it format queries with subqueries and JOINs?
Yes, subqueries are indented within their parent statement, and JOIN clauses with their ON conditions are clearly separated for readability.
Does it work with different SQL dialects like MySQL or PostgreSQL?
Yes, it handles standard SQL syntax common across major dialects, though highly dialect-specific extensions may format generically.
Is my SQL query uploaded to a server to format it?
No, formatting happens entirely in your browser using client-side JavaScript, so your query is never sent anywhere.
Does the formatter preserve SQL comments?
Yes, both single-line and block comments in your query are preserved in their original position.
Is there a more advanced formatter for very complex queries?
Yes, the companion SQL Query Beautifier (Advanced) tool handles complex nested subqueries and multi-table JOINs with more detailed formatting options.
