Frequently Asked Questions
Is my code safe when I paste it into the formatter?
Absolutely. All formatters run entirely in your browser using JavaScript. Your code is never sent to a server, logged, or stored anywhere. This makes them safe for production code, API keys, and sensitive data.
Can I minify as well as beautify code?
Yes, several formatters support both beautification and minification modes. The CSS Formatter and JSON Formatter include one-click minification to reduce file size for production deployment.
Do the formatters validate syntax?
Yes, formatters validate your input and display clear error messages with line numbers when syntax issues are detected. This helps you catch typos, missing brackets, and structural errors while formatting.
