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.…

Tooly▲5I kept opening online JSON formatters and getting buried in ads and popups. So I made a clean version with a few tools I actually use daily – JSON formatter with syntax highlighting, Base64 encoder/decoder, JWT decoder, text diff, and timestamp converter. Everything runs client-side. No tracking, no server calls, no signup walls. Built with React 19 and TypeScript. It's open source: https://github.com/chken007/tooly My 5-year-old helped name it. She insisted on "Tooly" and I couldn't argue with that logic. Open to feedback – especially if you spot bugs or have…
