Show HN: JSONXMLKit – Format JSON/XML and Decode Base64 in the Browser

2•makertoo•6h ago

I built this because I was constantly switching tabs to format JSON or XML, or decode Base64 — and many of the tools I found were either bloated, sent my data to a server, or just didn’t support things like XPath or JSONPath.

JSONXMLKit runs 100% in-browser, and includes:

JSON and XML formatters

Path search with JSONPath and XPath

File-based Base64 encoder/decoder (images, PDFs, etc.)

No login, no uploads. Just a set of quick, client-side tools I needed and decided to share. Feedback welcome!

I put this together after getting tired of using bulky or ad-heavy sites just to format JSON or XML. Everything runs in the browser and there’s no upload involved.

If you end up trying it, I’d love to know: What’s the one feature you’d want in a tool like this?

Thanks for checking it out!

Just tried it out — love how fast and clean it is. Nice to see something that doesn’t require uploads or popups everywhere.

Curious though — how does it handle really large JSON files? Are you planning to add YAML support too?

Yaml will be added soon yes. All you files are handled within your browser, so it really depends on it to handle large files (Json or Xml or encoded/decoded files).
