I have a dataflow that is connected to an Oracle table. Dataflow works okay, there is a null value in one of the rows. The data preview for the dataflow shows this as (null) All good. When I load data into Power BI from the dataflow the null value is converted into empty. Hence an extra step is required to replace empty with null. I need the null as I'm using PATH functions in DAX which require null. Is this a bug or feature?
Solved! Go to Solution.
Hi
As tested, if the column is of text type or contains many types, when connect to dataflow with Power BI Desktop,
These columns show "null" cells as blank cell in Edit queries.
When loading into data model, all columns regardless of type text, number, date,,ect, would show "null" celss as blank cell.
To solve it, select teh columns, replace blank cell with "null",
If the UI doesn't work, please change the code with "null" as below.

Hi @leehbi99 ,
I tried this in a text column, and a numbers column. The number column will only replace with a number like 0 if I use a find and replace. The text column will replace with null. Not sure that is your problem. If checking the column type does not work, try @ImkeF who knows all the back doors in M language.
If this solves your issues, please mark it as the solution, so that others can find it easily. Kudos are nice too.
