Your data is your data, period.
It's extremely simple to export your reviews from Junip. Simply navigate to the moderation section, then hit "export".
A popup will emerge confirming you want to export your reviews, it'll also remind you that this might take a while. If you only have a couple reviews, it should be a pretty quick process. With larger data sets, this can take a little bit of time.
Once completed, your export will display at the top of the moderation page. You can download the .csv here! 🎉
