Change #N/A to Blank cell

Question

How can I change the #N/A to the blank cell if nothing in that cell?

Eg. =VLOOKUP(B19:B36;$TABLE.A1:C46;2;0)

I think I might need something like an ISERROR check but I don't 100% know what I'm doing.

Answer 1

If we're talking about Excel 2010 and later you can use IFERROR:

=IFERROR(VLOOKUP(B19:B36;$TABLE.A1:C46;2;0);"")

You can also put text into the final string result

Answer 2

The question was misleading about the spreadsheet software as 2 different spreadsheets were originally stated in tags. However, it can be seen that the question is about OpenOffice Calc:
- Absolute sheet referencing ($ sign before the sheet name) is not possible in Excel.
- We also see a dot between the sheet name and the range, which is again not possible in Excel.

As in OpenOffice Calc you don't have IFERROR function, the only way is to repeat your main function twice in the following form (you can use both, ISNA and ISERROR, but I suggest ISNA as it's more specific and fits your case):

=IF(ISNA(YourFormula);"";YourFormula)

In your case something like:

=IF(ISNA(VLOOKUP(B19;$TABLE.A1:C46;2;0));"";VLOOKUP(B19;$TABLE.A1:C46;2;0))

You may want to make absolute reference to the range where you look for matching values, as I see you want to copy the formula down.

=IF(ISNA(VLOOKUP(B19;$TABLE.$A$1:$C$46;2;0));"";VLOOKUP(B19;$TABLE.$A$1:$C$46;2;0))
