exclude text values when using DATEDIFF

I'm using DATEDIFF to find the number of days between today and dates in column however the column also has some values that are text therefore the the calculation doesn't work. 

Can anyone advise how values with text can be exluded so that the Date difference will work on the values that are dates?

 

Column = DATEDIFF(Table1[Expiry],today(),DAY)

Hey @TIGER8855

you can do this with two steps in Power Query, create a new column with this code
try Date.FromText ([maybe a Date] )
otherwise null

Then change the data type to Date
This result might look like this:

Hopefully this provides what you are looking for.

Hey @TIGER8855 ,

 

this will not work because the DATEDIFF function requires the argument to be either of data type DATE or DATETIME: DATEDIFF – DAX Guide

Thanks @TomMartens . Do you know what is the easiest way to create a new column with just the dates and if there is text, the cell in the new column is blank? This way I can use the DATEDIFF on the new column with only the dates.

Thanks @TomMartens. That works. My original DATEDIFF can now be used on this new column.
