What is an SQL Formatter?
An SQL Formatter is an online tool that takes unformatted or messy SQL code and restructures it with proper indentation, line breaks, and casing, making it much easier to read, understand, and debug.
Which SQL dialects are supported?
Our tool supports a wide range of popular dialects including Standard SQL, MySQL, PostgreSQL, PL/SQL, T-SQL (Transact-SQL), SQLite, MariaDB, DB2, and BigQuery.
Can I change the capitalization of keywords like SELECT or FROM?
Yes! You can use the 'Keyword Case' dropdown in the settings to enforce UPPERCASE, lowercase, or preserve the original casing of the keywords in your query.
Does this tool execute my SQL queries?
No, this tool strictly formats your code textually. It does not execute queries, nor does it connect to any database.
Is my SQL code sent to a server?
No, all formatting is done entirely within your browser (client-side). Your SQL queries and schema details are completely private and never leave your computer.
Can I use tabs instead of spaces for indentation?
Yes, the tool allows you to select either spaces or tabs for indentation. If you choose spaces, you can also specify the exact number of spaces (e.g., 2, 4, 8) per indent level.
Why is my query showing an error when formatting?
The formatting library requires your SQL to be syntactically valid. If you have a missing comma, unclosed quote, or unknown syntax for the selected dialect, the formatter may fail and display an error message.
Can I format multiple queries at once?
Yes, as long as they are separated by valid statement delimiters (usually a semicolon ';'), the tool will format all queries provided in the input editor.
How do I download my formatted SQL?
Once your code is formatted, simply click the 'Download' button in the toolbar. This will generate a `.sql` text file containing your beautified query and prompt your browser to save it.
Is this SQL Formatter free to use?
Absolutely. The SQL Formatter is 100% free with no usage limits, no registration required, and no hidden fees.
