SQL Formatter
Format and beautify SQL queries for readability
About SQL Formatter
How SQL Formatter Works
Paste a query and it is rewritten with consistent indentation and casing in your browser. Formatting is fully client-side, so queries containing data are never transmitted anywhere.
The SQL Formatter takes a flat or messy query and rewrites it with consistent indentation, keyword casing, and line breaks so it is easy to read and review. A typical use case is cleaning up a generated or copy-pasted query before committing it, or understanding a long report built by another engineer. The formatter runs locally, so your queries and any embedded values are never sent anywhere, which matters for queries containing customer data. Well-formatted SQL is easier to review in pull requests and less prone to subtle logic errors. It helps teams enforce a uniform style without arguing over spacing and capitalization in code review.
Frequently asked questions
Does it change query behavior?+
No. It only adjusts whitespace and casing, never the logic.
Is my query uploaded?+
No. Formatting happens in your browser, keeping data private.
Which SQL dialects?+
It handles common ANSI-style SQL used by most databases.
Limitations
It does not validate syntax or optimize queries, and very database-specific extensions may not be perfectly styled.
