v-model prints [object Object] instead of the JSON string

I have a JSON object that I want users to edit.
When I print it plainly, like json I get the string, "car":"color":"blue". But when I print it in any sort of editable field, like
<input v-model="json">
I get this:
Things I've tried:
html:v-model/html:value- Empty input<textarea v-model="json">json</textarea>- I get[object Object], BUT when I inspect the element, I see the JSON printed like a string - which is what I want!
How do I get v-model to print JSON as a string in an input?

You can always use JSON.stringify(someObject) to get the stringified version of an object, however you cannot bind this via v-model.
If I understand you correctly, you do actually want the user to edit the stringified json and not provide input fields for the object properties? (The latter would be a much cleaner solution and could easily be achieved with a v-for="(value, key) in object" though)
But if that's the case, you also have to consider what to do when the user enters invalid json.
My approach to this would be to use a stringified version of the object to bind to the textarea v-model and watch it to determine on any change if it is a valid and parsable json format.
Working example here: https://codesandbox.io/s/ol9nn9j566
It'd probably need some debouncing, and better error handling but it should get you started.
