Since my most visited post is Formatted JSON In Notepad++, I decided it would make a good subject for my first attempt at a video tutorial.
Since my original post, I've discovered a plug-in I like even more: JSTool.
This tool not only has more features than JSONViewer, but it doesn't have the annoying requirement that you select the JSON text before applying it.
JSTool will help you make minified JSON readable the same way JSONViewer does, but it can also go the other way. It can minify your JSON for you.
Getting The Plug-Ins
Getting any plug-in in Notepad++ is as simple as going to the Plugins menu and clicking Plugin Manger: Show Plugin Manager. From there you get a nice dialog that lets you search for plug-ins. In this case just search for JSON.
Let me know in the comments on the YouTube video if you like it, or if you have ideas for other tutorials you'd like to see.
I'm currently planning a beginner's guide to SQL series.
