Microsoft Power BI Data Analyst Practice Question

You connect Power BI to a CSV export that contains a column named Attributes whose cells hold JSON text strings. You must transform this semi-structured content so that each row displays the FirstName and LastName properties as separate columns. In the Power Query Editor, which transformation should you apply first to the Attributes column before expanding its fields?

  • Convert the column to a List and then use To Table.

  • Transform > Parse > JSON to change the text strings into Record values.

  • Invoke a custom column function that wraps each value with Json.Document.

  • Split Column by Delimiter using commas and colons.
