Getting value from 2 columns to create one column

[igonzalez_ep]

I want to create a new column that will give me the value of columnA if theres a value but if there isnt get the value from columnB otherwise jut give me a null.

I already tried the following formula but i only get values from columnA:

= IF(ISBLANK([ColumnA]), [ColumnB], "null")

and = IF(ISBLANK(ColumnA), IF(ISBLANK(Column),"null",Column),ColumnA)

I also cleaned up the columns for any hidden characters. 

Let me know if you have any thoughts to get this to work.

Thank you

Hi @igonzalez_ep 

You should use the LEN function to check if the "blank cell" is really blank.

Hi @igonzalez_ep 

First, I would confirm that the columns contain true blank values.

One method: in Table view, click the filter dropdown:

Empty string (not blank)

Actual Blank:

You may need to replace empty string values with nulls in Power Query:

Null values in Power Query will appear as italicised null in the Power Query Editor.

Once you are sure you have blank values in the relevant columns, you could create this DAX calculated column:

= COALESCE ( YourTable[ColumnA], YourTable[ColumnB], "null" )

 You could also add a custom column in Power Query with this expression (using the null-coalescing operator ?? )

= [ColumnA] ?? [ColumnB] ?? "null"

 Does any of the above help?
