    Abhaykumar You can also select individual columns in query editor and click Remove Duplicates.

    Hi Abhaykumar,

     

    Use DAX and in DAX the function SUMMARIZE().

    Summarize will pull out distinct values from columns.

     

    So your resultset will be new table from Summarize

    Table_Output =  Summarize(Table_IN,Col1,Col2,Col3)

     

    I hope it helps !

     

    BR,

How can I copy distinct values from multiple columns into ONE single colum?

 

The shown above always created multiple columns into which the code copies the distinct values from each column.

 

Thanks!

This formula will create a list of distinct values in the query editor (where "Source" is the name of the table/previous step and column names in square brackets):

 

List.Distinct(List.Union({Source[Col1], Source[Col2], Source[Col3]}))

Not sure if you want this as a standalone query or merge the resulting list with some other table?
