Choose columns from list

Howdy. I've got monthly data that I receive across 2000 zones, of which I only need a few hundred. I have a list of the ones I need and I'm trying to use  table.removecolumns with the list as a reference but keep getting errors. I know I could manually just pick the ones I need, but where's the query fun in that? Sample data below, I can provide a sanitzed pbi book if needed

Hi @whiskeybravo91 ,

 

Please make sure the type of the list is in text format in the Power Query Editor instead of Desktop model.

Or you can try the Number.ToText function to convert the type of the list to text.

 

= Table.RemoveColumns(#"Changed Type", List.Transform(pixellist, each Number.ToText(_)))

I found the error. The list I had contained selections from another tab, not just the tab I was using for the example. So the data is broken across zones, zones 1-10 on a tab, 11-20 on a tab, etc etc. The list I was using had all the ones I needed across all the tabs. Once I adjusted the list to just have the values on the 1st tab, it worked like a dream. Thank you!

@whiskeybravo91 or you can add a step by removing a column and changing that remove column step to this

 

in the following code, columntoremove is  a table that has a list of columns you want to remove and remove is a column in that table, you can change these values as per your table/column names

 

Table.RemoveColumns(#"Some Ste",ColumnToRemove[Remove])

@whiskeybravo91 you should unpivot your data and then it is super easy to filter.
