Frequently Asked Questions
Everything you need to know about processing files securely in your browser
Which SQL dialects are supported by this formatter?
The formatter works with standard SQL syntax and is compatible with major databases such as PostgreSQL, MySQL, SQLite, SQL Server, and Oracle.
Is my database query kept private?
Absolutely. Formatting is done locally in your browser using JavaScript. No SQL queries, database structures, or data contents are ever transmitted to any external server.
Can I customize the indentation of the formatted SQL?
Yes, you can choose between spaces (2 or 4) or tab indentation, and choose whether to capitalize SQL keywords (like SELECT, JOIN, WHERE) for consistent style.
How does formatting help with database debugging?
Cleanly formatted SQL queries with proper nesting, alignment, and keyword capitalization make it significantly easier to spot syntax errors, trace complex table joins, and debug query logic.
