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

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