Expanding multiple lists (import from JSON file)

[Liam79]

I need multiple lists to be extracted and displayed in a table.

In column A, I have a list of 136 items (rows).

In column B, I have a value that corresponds with column A, many of which are [Lists].

How can I expand all of these lists into the table?

Hi , @Liam79 

According to your description, in the column , you have the text type and also have the [list] type.

Here are the steps you can refer to :
(1)This is my test data:

(2)We can click " Insert Step After" to add some steps:

(3)We can add three steps here :
= Table.SelectRows(Source, each [Column1] is list )

= Table.ExpandListColumn(FilterList, "Column1")

= Table.SelectRows(Source, each not([Column1] is list) ) & #"Expanded Column1"

(4)The result is as follows:

If this method does not meet your needs, you can provide us with your special sample data and the desired output sample data in the form of tables, so that we can better help you solve the problem.

Thank you for your time and sharing, and thank you for your support and understanding of PowerBI!
