JSONBason▲15
I'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.…
