Hello @Edwin ,
Welcome to the Microsoft Q&A platform, and thanks for posting your query.
Please correct me if my understanding is wrong. You are looking to unroll the array values inside the JSON into individual rows.
Based on your screenshot I am assuming below is your JSON.
{
"Parlors": ["1", "2", "3", "4", "5", "6"]
}
Here are the steps on how to use the flatten transformation to unroll the array values into individual rows.
My source file is pointed to the JSON file on the blob storage.
On the projections tab, click on import projects and you can see the column “Parlors”
Add flatten transformation and in the flatten settings you can see “Unroll by”. Select the Parlors and map the input column.
On the inspect tab, you can see input and output columns
Go to data preview and click on refresh to see the values.
here are my output values with the flatten transformation.
Please check the video tutorial below to understand more about Flatten transformation.
