Frequently Asked Questions

Are code formatting and token decoding operations secure?
Yes. All developer formatters, JWT decoders, SQL utilities, and cryptographic hash generators operate 100% client-side in your browser. No source code, payload data, or secret keys are transmitted to any server.
How do I test and debug regular expressions?
The Regex Tester provides real-time pattern matching with syntax highlighting, group capture extractions, flag toggles (g, i, m, s), and explanation guides for complex expressions.
Can I format and minify SQL queries for production?
Yes. The SQL Formatter indents complex JOINs, CTEs, subqueries, and window functions for readability, while the SQL Minifier strips unnecessary whitespace and comments for lightweight query payloads.
