[ x ] Data Populator for Sketch

I don't want to always have to create a json file with my data

**Describe the solution you'd like**
Would be awesome if I could just paste in data directly. Without needing a json file somewhere. Great for copying from a source.

**Describe alternatives you've considered**
Can't think of any
