I wouldn't do it.

It sounds like you can group your data in the pivottable by month and year and
have exactly what you wanted.

But you could use a formula like:
=text(a1,"yyyy-mm")
to do the conversion.

(But try that grouping in the PT first. You'll like it.)

Assistance with removing day from date format. Wish to change column of
dates which are in format mm/dd/yyyy to new value yyyy-mm. Converted dates
in column are then to be used in a pivot table, to sort data by monthly
occurances. The pivot table presently sorts by daily occurances as the date
is in mm/dd/yyyy format.
