Frequently Asked Questions

Common questions regarding our client-side developer tools and browser security.

Is it safe to paste confidential API responses and JWT tokens here?

Yes. Because our utilities operate 100% client-side via native browser JavaScript APIs, no text or code is ever transmitted to our servers or saved in server logs.

Does the JSON Formatter validate syntax errors?

Yes. It performs real-time parsing against RFC 8259 specifications and highlights exact syntax errors, missing quotes, or trailing commas.

Can the CSV to JSON converter handle comma-separated values inside quotes?

Yes. The converter implements full RFC 4180 parsing, properly handling escaped quotes, commas inside text columns, and custom delimiters.

What color formats does the Color Picker support?

The Color Picker inspects and translates HEX, RGB, RGBA, and HSL formats, while generating complementary, triadic, and analogous palettes with WCAG contrast ratios.
