The Replace All does not function in the attribute table when trying to convert a number to Null in the numeric type fields in ArcMap.

Additional Information

Workaround

A Python query can achieve this. However, this query only works on one field at a time.

In the Field Calculator, select the Python parser, and check the Show Codeblock check box.

In the Pre-Logic Script Code box, copy and paste the following code:

def updateValue(value):

if value == 0:

return None

else: return value

Type the following code in the second box, and replace '!Field_Name!' with the field name from the fields list, as required:

updateValue(!Field_Name!)
