fastgron: A JSON to GRON Converter That's 40 Times Faster Than Gron▲23
Hello HN! I want to introduce fastgron, my new project. fastgron is a JSON to GRON converter, built to be incredibly fast – it's 40 times faster than Gron. GRON is a tool for making JSON greppable, but it can slow down with larger files. With fastgron, even a 200MB JSON file can be converted in just 1 second. Key features include streaming conversion for memory efficiency and an optimized path reconstruction for faster operations. It leverages C++ and the simdjson and fast_io libraries for speed. I welcome all feedback, suggestions, or questions. Thank you!

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.…
