You have a combination of CSV import and JSON decode
First, you import the CSV file, which will give you an array with an object of two fields:
- products.product.id
- products.product.description
The 2nd part, which is JSON decoding, I don't have enough experience in Wappler to point you in the right direction without being sure, but it's certainly possible.
I'd probably create a new empty Array, define the schema, and then repeat (iterate through) the old CSV array, and do a Set Value to push the $value (JSON decoded through a [custom] formatter on the Data Format/Data Binding Picker) to the new empty Array we've previously created
