Sometimes it's easier to validate the syntax with JSON lint first: https://jsonlint.com/
Thanks for the replies, I fixed it up to a point and then ran into a code blocker that I don't understand using the validation website: https://jsonlint.com/

Usually means you need another closing curly brace } somewhere in the json - either at the end or further up. I think its your "overrides" group that is not closed at the end.

Thank you, turns out I needed a couple more. So now my json checks out, but unfortunately I still don't see it listed under "Add Printer" :( Are there any other reasons besides issues with the json that would prevent the printer from showing?
Instead of pasting the json here, which consistently screws up the file beyond our being able to properly check it, could you post it on pastebin.com and post a link here?
Here's the pastebin:
Your definition file is in the format of Cura 2.1. It lacks a metadata section, and from Cura 2.3 on there is no "machine_settings" section but only a "overrides" section. Please have a look at the definitions that are currently in the resources/definitions folder.
The CuraProfileMaker should be updated, or the reference to it should be removed.
A lot of the profiles are in that format. For example the Lulzbot Taz 6, and it shows up just fine. I don't understand why one definition would work in the older format, but another won't.
There is no Lulzbot Taz 6 definition in Cura 2.x (unless you are running the alpha build of the Lulzbot Edition of Cura 2, in which case please ask them for support). These are are definitions that come with Cura 2.7:
https://github.com/Ultimaker/Cura/tree/master/resources/definitions
What version of Cura are you using?
I'm using Cura 2.6.2. I guess I can update to Cura 2.7 then update the .json file and see if I have any luck with that.
So it turns out that updating to Cura 2.7 and then updating my .json file to reflect the 2.7 changes worked. I was able to get Cura to recognize not only my printer but the extruders as well. Thanks for all your help!

UltiMaker Cura 5.8 Stable released 🎉
MariMakes posted a topic in UltiMaker Cura,
In the Cura 5.8 stable release, everyone can now tune their Z seams to look better than ever. Method series users get access to new material profiles, and the base Method model now has a printer profile, meaning the whole Method series is now supported in Cura!-

First thing I see is two commas (,,) after "inherits": "fdmprinter.json",,
However, json files are very strict on format, structure and indentation, so there could be issues there that can't be detected in your copy/paste.
Use the code tags, > to place your json code in to retain the formatting, spacing and indentation. I will help a lot.
It'll also get rid of those emoticons...
