Features & Usage
How do I format SQL?
Paste your SQL query into the input area and click "Format SQL". Toggle options for uppercase keywords, line breaks, and clause indentation to customize the output.
Does the formatter support CTEs?
The formatter handles basic WITH clause syntax by preserving the keyword and structure. For complex CTE chains, you may need to adjust indentation manually.
Can I format SQL from different databases?
Yes. The formatter recognizes keywords from MySQL, PostgreSQL, SQL Server, SQLite, and Oracle, and formats them consistently. Dialect-specific syntax is preserved.
Troubleshooting
What happens when Uppercase Keywords is off?
With Uppercase Keywords disabled, the formatter preserves the original case of SQL keywords. Line breaks and indentation are still applied normally.
Can I use this tool offline?
