I see an Export/Download tab in your screenshot. Isn't that working for you to create a JSON backup? That would allow you to see how the file is formatted and possibly add your own replacements if that is what you want to do. Otherwise you can try to contact its creator for help.

Sorry, I should've been clearer; I meant I want to export a JSON file from the text replacement on my Mac OS so I can upload it to 'text fast'.

A Google search shows that you can export to a Text Substitutions.plist file.
