Frequently Asked Questions
Is my SQL kept private?
Absolutely. All formatting happens entirely in your browser. No SQL is sent to any server, logged, or stored anywhere. You can safely use this tool with production queries.
Which SQL dialects are supported?
This formatter supports standard SQL and works with most popular database systems including MySQL, PostgreSQL, SQLite, SQL Server, and Oracle. It handles common SQL syntax elements like SELECT, INSERT, UPDATE, DELETE, JOIN, and more.
What's the difference between Format and Minify?
Format beautifies your SQL with proper indentation and line breaks for readability. Minify removes all unnecessary whitespace to create a single-line SQL string, useful for embedding in code or reducing network payload.
Can I format very long queries?
Yes, the tool can handle SQL queries of substantial length. There are no strict limits, but extremely large queries (tens of thousands of lines) may impact browser performance.
Does this validate SQL syntax?
This tool focuses on formatting, not validation. While it handles most standard SQL structures, it does not check if your SQL is syntactically valid for your specific database engine.
