Download the sketch-data-parser.sketchplugin file and double click it to have Sketch install it in the right place.
The plugin uses a JSON to populate a list of predefined layers, here is an example :
First, you need to create a group (which will be the model group) with the current naming convention for your editable layers :
$[name of your data]
Example :
Warning : the current version of the plugin doesn't include sub-folder, so you have to keep your editable layers at the first level of your model group
In a second time you need to create a JSON with your data :
[
{ "name" : "Doris Chapman", "age" : 32, "diet" : "vegan" },
{ "name" : "Hudson Anderson", "age" : 23, "diet" : "low carb" },
...
]
And now you just have to run the plugin, paste the JSON in the prompt and Sketch will automatically duplicate the group for you and populate the new data inside.
Based on the needs I'm planning to add a way to use URL to use pictures.
If you have suggestions, or want to improve my code just do it!
