SQL Formatter
Format and beautify SQL queries online with custom indentation and uppercase keywords.
Run tool
Format raw, minified, or disorganized SQL statements into clean, structured queries. This online tool processes queries up to 1,000,000 UTF-8 bytes, aligning clauses and converting standard SQL keywords into uppercase for clear readability. You can configure your preferred indentation width between zero and eight spaces, with a standard default of two spaces per nesting level. Multiple SQL statements in a single run are cleanly separated by semicolons and line breaks, concluding with a trailing semicolon. While a dialect field is provided, the tool applies a standardized generic formatting pattern across your input. Enter your query text into the input field, adjust the indentation level if needed, and run the formatter. The tool immediately generates formatted SQL ready to copy into your query editor, documentation, database scripts, or code reviews. Blank or whitespace-only inputs safely return an empty result without errors.
Instructions
- Paste or type your SQL query into the SQL input box.
- Set your desired indentation level from 0 to 8 spaces, or leave the default at 2.
- Leave the dialect field as generic or specify your dialect.
- Click Run to format and standardize your SQL statements.
- Copy the structured output directly from the result box.
Examples
- Input: select id, name, created_at from users where status = 'active' order by created_at desc; Output: SELECT id, name, created_at FROM users WHERE status = 'active' ORDER BY created_at DESC;
- Input: insert into orders (user_id, total, status) values (42, 199.99, 'completed'); Output: INSERT INTO orders (user_id, total, status) VALUES (42, 199.99, 'completed');
FAQ
Does this tool execute queries or connect to a live database?
No, the tool only parses and formats query text. It does not connect to any database or run your SQL statements.
What happens if an indentation value outside 0 to 8 is provided?
Indentation values below 0, above 8, or non-integer inputs automatically fall back to the default of 2 spaces.
How are multiple queries handled in one run?
When you format multiple SQL statements together, each statement is separated by a semicolon and newline, with a trailing semicolon at the end.
Does the tool validate dialect-specific syntax?
No, the formatter applies a generic formatting style and does not perform dialect-specific syntax checks or transformations.
