IF DAX

BurakTurk - Not sure what you're trying to do here, but here's a breakdown of the DAX I used: 

NewValue = IF(File[Value]="YES", "1", IF(File[Value]="NO", "0", File[Value]))

1. Create new calculated column called "NewValue"

2. If File[Value] = "YES" then insert a "1" into NewValue

3. If File[Value] = "NO", then insert a "0" into NewValue

4. If File[Value] is not equal to either YES or NO, then insert the value of File[Value] (that would be your original 2, 3, 4, ...) into NewValue.

The result is a column (NewValue) in the same table that has either a 1, a 0, or the original number from File[Value] in it.  Is that not what you wanted?  Not sure what you mean by "file [value] part, unfortunately, does not work on its own"; I tested it in PowerBI and it works.
