Getting apk or data from ionic view

I made a huge mistake today. I accidentaly overwrote a json data with an older one. It has a lot of info in it. The only place with the correct json is the uploaded app in the ionic view. Is it possible to get it from there?
Thanks in advance!

I found a solution! I rooted my phone, managed to access the ionic view data and from there, I restored the json file!
