Remove duplicate words in a cell after power query grouping and aggregating from a table

Hello,

 

I am using a power query to group and aggregate columns of a table. After the power query, the aggregated columns contain duplicate values. For example one of the aggregated columns is ISO country code, so after aggregating the cells contain "UK, UK, FR, FR, FR, DE, DE" etc. Is there a step I can add to the power query to remove such duplicates?

 

Thanks!

    As variant you may aggregate ISO as sum, that will return an error, in formula bar will be something like this

    Change in formula bar on that

    Other words instead of List.Sum first List.Distinct to remove duplicates, on the top Text.Combine to have one string.

    With that doesn't matter how many aggregations you have, you correct only specific one.

      OliverScheurich Thanks for your reply! Unfortunately I don't think this will solve it. Below is a screenshot of the grouping - if two or more Channels feature the same country, then removing duplicates prior to grouping won't work...
