Where do I find the Theme JSON files?

[suzsword]

Hi 

I have been tasked with creating a Theme for my company that can be used in Power BI. I know I need a JSON file but I would like to use an existing one as a template but I can't find the files. 

Can anyone tell me where to locate the theme json files on a Windows 10 machine?

Thanks

Susan

Just look in your downloads and it should appear

I'm not sure I understand, why is it in my download folder? I haven't downloaded anything.
