How to combine three columns into one?

[melian]

Hi, 

I have a table that has three columns (Zip codes columns). I want to combine all of them into one column that has all the zip codes. How can I do that?

Hey!
There's no build in function in Power BI for that, but you can use M/Power query. 

(Source) =>
    let
        result = Table.FromList(List.Combine(Table.ToColumns(Source)), null, {"AllZipCodes"})
    in
        result

 Just google for how to apply Power Query to your Power BI. 
However this function replaces all your columns. If you want to keept the old columns you got to customize the function. 

Cheers Jakobob

This is an example of what I want to do. In the table I am working on there are three columns, the first three, of zipcodes. I want to combine all of them into one column, All ZipCodes.

Hi,

Use Summarize with union function as shown below-

AllZipCode =

UNION(SUMMARIZE('Table','Table'[ZipCode1]),SUMMARIZE('Table','Table'[ZipCode2]),SUMMARIZE('Table','Table'[ZipCode3]))

@Anonymous , Have you written the union dax formula on "Create a new table using DAX" pane?

@Anonymous , i got if after using the dax in a new table, is it possible to combine them in the same table?

What i want: am planning to show the hours spent on each project on a particular date, i have 4 columns of project IDs for each person everyday hence i want to combine the IDs into one column.

Hi Melian, Can you please post your solution DAX . I have the same requirement but UNIOn is not working in my case.

@melian,

You may select Unpivot Columns in the Query Editor or use UNION Function in DAX.

@v-chuncz-msft Thank you so much. The UNION function did the job. Much appreciated.

CONCATENATE([col1],CONCATENATE([col2],[col3]))

The problem with this is that it combines them on the same line, which is not what I want. Your code would make the the new list looks like this 

 

However, I want the new list to look like this
