Expand Column - REST API JSON Records
I have bring data to PowerBI through an REST API Endpoint. I have two questions:
1) How do I expand the customer column so I get the value only (there are two column the customer records link/values) (Picture 1)
2) Why do I see 'expand' icon (two arrow) in some columns which allow me to pick the column and not in other column e.g. customer (Picture 2)
smerchant,
The column with two arrow contains all the fields recorded in your JSON file, and some fields(e.g. customer ) contain nested arrays, these fields only have one arrow after you import data from JSON to Power BI Desktop.
To expand the customer column, please follow hugoberry's suggestions in this similar thread.

Lydia ZhangHello,
Taking this further, I have 20 JSON files with 20 columns each to import. Rather than click, click, click, what is the programmatic method for importing these?
Specifically:
- How do I convert JSON to table
- Expand all columns
- Drop some columns
- Rename some columns
This is all manual at the moment.
Thank you!
