FAQ
Does this tool validate SQL syntax?
No, this is a formatter only. It reformats your SQL for readability but does not check for syntax errors. For validation, use a database-specific tool or IDE.
Is my SQL query stored on your servers?
No. All formatting is done client-side in your browser. Your SQL queries are never sent to or stored on our servers.
What's the difference between dialect options?
Each dialect option adjusts keyword handling and syntax-specific formatting. MySQL uses backticks for identifiers, PostgreSQL uses double quotes, and SQL Server uses square brackets.
