Frequently Asked Questions
Why does the SQL dialect matter?
Different databases have distinct quoting styles, keywords, and syntax rules — like MySQL's backticks vs. T-SQL's square brackets. Choosing the right dialect ensures the most accurate formatting output.
Does minification change my SQL logic?
No. Minification only strips redundant whitespace and newlines. Your statement logic, column names, and condition values are fully preserved — ideal for reducing payload size before deployment.
Can I format multiple statements at once?
Yes. Paste multiple semicolon-separated SQL statements into the editor and the formatter will automatically recognize and beautify each one uniformly.
Can it handle very large SQL files?
Absolutely. Thanks to CodeMirror's virtual scrolling and the performance of modern browser engines, even files with tens of thousands of lines are handled smoothly.
