Hi @Anonymous ,

 

Based on my test, if your column only contains "List", it can be expanded directly.

Please check if there are some "Record" in your column, too. 

record with list.jpg

 

If so, you can refer to this post:

transformation - Transforming json with power query (mix of list and record in a single column) - Stack Overflow.

 

 

Best Regards,

Familiarize yourself with the try ... otherwise ...   pattern in Power Query.  Hint: for the "otherwise"  portion you may need to provide an empty list.
