Frequently Asked Questions

Do these tools upload my code anywhere?

No. All developer tools run entirely in your browser. Your code never leaves your device, which makes them safe for proprietary and sensitive source code.

Can I convert HTML to React components?

Yes. The HTML to React converter transforms HTML markup into JSX components with proper camelCase attributes and self-closing tags.

Is the JSON formatter free?

Yes, and it handles nested objects, arrays, and minified JSON while letting you validate, minify and copy results in one click.
