This we app lets you format/edit/minify multiple json at the same time. With focus on various small productivity tricks like -
1. Copy a child object in a click
2. Copy minified string in a click
3. Remove common problems
4. Give a filename and download edited/formatted JSON in a click
It might (or might not) be worth making a short "screencast" style animation showing these things if making one is easy enough. I say this because my experience felt like landing in the middle of a random editor...the page didn't provide any context...so maybe a minimum landing page listing these features is a more reasonable alternative to an animation. Yes, a landing page probably is a better alternative to an animation. And to me, it's a better alternative to dropping first time visitors into the editor. Good luck.
Thanks for the feedback!
Yes, I have been thinking of creating a "How do I" or "Help" page. I have created small videos/GIFs of few features. Will embed them on the website.
