The IFERROR Function of Excel
The IFERROR function has a very specific use in Microsoft Excel. It was created to remove error messages when errors occur within cells. Here well look at the syntax of the function, errors messages that can be hidden and an example of this functions use.
Syntax of the IFERROR Function
The IFERROR function has a very simple syntax shown below.
=IFERROR(value, value_if_error)
There are two argument that are required to use this function.

Value
This needs to be a cell reference, a calculation, a function or series of functions.

Value if Error Occurs
This value can be what you want it to be. To display nothing simply use "" for this argument. If you want to add text for a number as text then put them inside of quotes.
Errors Messages that the IFERROR Function Can Hide
These references are provided to show what error messages the IFERROR function can hide. Each error is described in detail. Note that there may be more reasons for these errors to occur besides what is listed below.
#NULL! – Cell references are separated incorrectly.
#N/A – Can’t find referenced data.
#NUM! – Invalid numeric value.
#REF! – Specific reference is not valid within an argument.
#DIV/0! – Division by zero.
#NAME? – Text within a formula is not recognized.
#VALUE! – The wrong type of function or operand has been used.
IFFERROR Example
In the example below, I have an error because one piece of data is missing from one of my reference inputs for an equation. As a result, an error is displayed. Instead of having the error message "#VALUE1" appear when I have this error, I would like a custom message to appear for the user of the worksheet.
The IFERROR Solution
The formula that is causing the error is shown below.
=2*(1NORMSDIST(ABS((H12H8)/(H9/SQRT(H11)))))
The error is occurring because the cell reference H8 in the formula is missing from the H8 field. There are a few steps to replacing the error with a custom message.
 Step 1. Click in the cell and position the cursor after the equals sign.
 Step 2. Type IFERROR(
 Step 3. After the last parenthesis, type a comma
 Step 4. Type the message that you choose to appear in quotes
 Step 5. End with a closed parenthesis and enter
Completing these steps will replace the error for a custom message.
