How do I ignore "#N/A" data in a column while calculating average

Try one of these:

=SUMIF(A1:A10,"<1E100")/COUNT(A1:A10)

This one is an array formula** :

=AVERAGE(IF(ISNUMBER(A1:A10),A1:A10))

** array formulas need to be entered using the key combination of
CTRL,SHIFT,ENTER (not just ENTER)

Hi,

Try this array entered formula

=AVERAGE(IF(ISNA(B1:B7),"",B1:B7))

being an array you must enter it by pressing Shift+Ctrl+Enter

In 2007 you can use

=AVERAGEIF(B1:B7,"<9E9")
