Have a bunch of values and you need to check which ones are errors? The ISERROR Formula in Excel is perfect for this!

There are a couple of interesting points to take note of the ISERROR Formula:

• The following are treated as errors by the ISERROR Formula
  • #N/A
  • #VALUE!
  • #REF!
  • #DIV/0!
  • #NUM!
  • #NAME?
  • #NULL!

I explain how you can do this below:

STEP 1: We need to enter the ISERROR function in a blank cell:

=ISERROR(

 

STEP 2: The ISERROR arguments:

value

What is the value to be checked?

Select the cell containing the value you want to be checked if it is an error:

=ISERROR(C9)

Apply the same formula to the rest of the cells by dragging the lower right corner downwards.

You can now see which ones are errors!
