JSONXMLKit▲13
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!
