I have reviewed the Microsoft documentation for custom themes. I have also reviewed some online resources, including this very helpful repository (https://github.com/deldersveld/PowerBI-ThemeTemplates). I am still left a little wanting.
Does anyone know the keys to set the following properties in the JSON template file:
(1) the various TRUE/FALSE toggles on the Visual Header
(2) the default values on the "Field Formatting" card for Matrix/Table visual (i.e., what the values revert to if you hit the "Revert to Defaults" option at the bottom of the card).
Thanks in advance for any help!
Hi, @MasterP
To create an extended-format JSON file, with more detailed and granular control over all visual formatting in a report, add a visualStyles section to the JSON file to nest the formatting specifics.
For more details, Please check the content related to Setting visual property defaults (visualStyles) in this article.

Thank you for this reply. As mentioned, I have reviewed that document, and the json code provided, and it does not appear to address the two areas I mentioned. Do you have a link to an authoratative list of settable properties, in a format that is understandable?
@MasterP I found this post, not sure if this is what you are looking for.

Thanks, but that is only about whether it is on or off. I can't seem to find the json names for the other aspects of that card.
