# **IFERROR practice in Google Sheets**

IFERROR returns its first argument, or a value of your choice if the first argument is an error. In Google Sheets it works as in Excel and is most often wrapped around a lookup.

[**Start the first exercise**](https://practiceexcelonline.com/sheets/practice/iferror/iferror-vlookup)

IFERROR(

1. [**1****Hide #N/A with IFERROR**IS is not in the table, so a plain VLOOKUP shows #N/A. In E2, wrap VLOOKUP(D2,A2:B6,2,FALSE) in IFERROR to show "Unknown" instead.](https://practiceexcelonline.com/sheets/practice/iferror/iferror-vlookup)
2. [**2****Avoid #DIV/0! with IFERROR****Premium**The lamp has not sold yet, so B2/C2 gives #DIV/0!. In D2, wrap B2/C2 in IFERROR to show 0 instead.](https://practiceexcelonline.com/sheets/practice/iferror/iferror-div0)
3. [**3****Catch only "not found" with IFNA****Premium**E-109 is a new hire who isn't in the list yet. In E2, look up the department for D2 with VLOOKUP and wrap it in IFNA to show "Not listed" instead of #N/A.](https://practiceexcelonline.com/sheets/practice/iferror/ifna-vlookup-not-found)

## **Questions**

<details>

<summary>

### Can I leave out the second argument of IFERROR in Google Sheets?

</summary>

Yes. Google Sheets then shows an empty cell instead of the error. Writing "" as the second argument gives the same result and works in Excel too.
