Take values from two comma separated lists to fill new columns

[fraggl]

Hello community members,

I'm still a newbie with PowerQuery and PowerBI and learning a lot from your valuable solutions.

Maybe you can help me with the following:

In a PowerBI query I have the following situation in a table:

Categories	Values per category	...<other data>	...<even more data>
10,12,13,14,29	0,1,10,5,4
10,11,12,13,19,14,15,17,18,23	0,0,30,40,0,30,40,80,50,25

I have a second query that gives me the categories by id and name:

id	Name
10	Category A
11	Category B
12	Category C
13	Category D
14	Category E
15	Category 100
16	Category 120
17	Category F
19	Category G
23	Category H
29	Category Z

What I want:

In my first table, I want to "decode" the category ids from column "Categories" to single columns with the category names from my second query and to fill the values per category in the corresponding columns. I don't want to have lines per value with all other cloumns repeated per line, but the columns as shown in the example:

Categories	Values per category	Category A	Category B	Category C	Category D	...		<other data>	<even more data>
10,12,13,14,29	0,1,0,5,4	0		1	10	...
10,11,12,13,19,14,15,17,18,23	0,0,30,40,0,30,40,80,50,25	0	0	30	40	...

Any help is highly appreciated.

Hi @fraggl ,

You can first get the following table by some steps.

Then use merge queries and pivot column to get the final result.

You can download my attachment for more details.

You can view the details in the applied steps.
