Replace blank values with "Null" keyword using measure

[anandmitta]

Hi,

I have a table visual with contains many date/time rows and columns.

There are many blank values in the table. Is it possible to replace all the blank values in the visual with text: "Null".

Can this be achieved with a measure rather than replacing the blank with "Null" in power query?

Can we replace the blank values in all columns in the table visual using a single measure rather than using multiple measures for multiple columns?

Any help would be appreciated.

Thank You

Hi @anandmitta ,

It seems you are using Live Connection mode. It means you  can only make changes to it on the Desktop. So it seems that you can only use measures or use calculate table.

Please have a try.

NewTable = 
VAR midT =
ADDCOLUMNS (
'Table',
"Date_", IF(ISBLANK('Table'[date]),"NULL",FORMAT('Table'[date],"YYYY-mm-dd")),
"Start_",IF(ISBLANK('Table'[start]),"NULL",FORMAT('Table'[start],"YYYY-mm-dd")))
RETURN
SELECTCOLUMNS ( midT, "Date", [Date_], "Start", [Start_] )

Hi,

Replacing in the same columns can only be done in the Query Editor.

Hi, @anandmitta 

Try something like:

Measure = IF(ISBLANK(Table[Date]), "Null", Table[Date])

When I use the ISBLANK() function and trying to select a column in the ISBLANK function, it's throwing error.

This is strange, can you share what is the error?

[anandmitta]

It's asking for aggregate value to use in the ISBLANK() function

If you use a measure in your table you can use it:

Measure = IF(ISBLANK([MeasureinTable]), "Null", [MeasureinTable])

Note that if the measure here doesn't return text values, then you may get an error about IF returning different data types. You can fix this by wrapping the measure with FORMAT. and specifying the format you'd like (e.g. "General Date" or "yyyy-mm-dd" or "c" etc).
