Circling back to add one more comment in case this makes it on the roadmap at some point. When importing conversations, there are a number of situations where simply being able to paste in the json text might be easier than uploading a file if that would be possible.

That would be a really nice addition. I will say, I would rate the ability to export and import individual conversations higher than a feature that exports all history. The ability to bring one or two conversations over to my work phone for example would be nice. No need to be importing all of my conversations over for example. Or, the ability to send one conversation json file to someone else, and they can continue off of it, would be really useful. I wouldn’t want to send all my of conversations to someone else necessarily.
