Parse/Manipulate Data

[ ] Data Populator for Sketch
[X ] Data Populator for Adobe XD

**Is your feature request related to a problem? Please describe.**
No

**Describe the solution you'd like**
Ability to parse/manipulate JSON data. For example, we have timestamps that look like this "2021-03-09T14:53:31.859+0000" I would like the ability to write JS inbetween the curly brackets so I can format the data into a more user-friendly format in the mockups. 

**Describe alternatives you've considered**
None available
