JSONXMLKit▲13I 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!

JSONBason▲15I've been at it again, just sharing my simple JSON data inspection tool, love webdev and single page apps, this one took 4 days and was a lot of fun. The code is not obfuscated so you can inspect it and see how it works (very simple, server side is even more simple) Pretty much just do a POST of your JSON data from within your code and it will convert it into a basic table for instant search and sort. Made with love for the fun of it, no ads, no paid anything, it's totally free. Please only send in sanitized/test data only, this is meant to help make webdev a bit easier and more fun.…
