How do I define an excel function that returns a blank if the result of the formula is blank?

If vlookup finds a blank, it returns a zero. I’d like to embed vlookup in a function that, if vlookup finds a blank cell, returns a blank instead of a zero.

I don’t want to have to type out:

`=if(vlookup(args) = "", "", vlookup(args))`

I would prefer to have something similar to the built in Iferror function whose syntax would be:

```
=blankreturn(function)
```

Which would return a blank if the function results in a blank, or the result of the function if it does not.

I have tried to define a custom function but it still returns a zero when it finds a blank cell

```
public Function Blankreturn(formula as variant)
If IsEmpty(formula) = True Then
Blankreturn = ""
Else
Blankreturn = formula
End if
End Function
```

Or even better, though I wouldn’t know where to start with the code for this:

```
ifblank(function, "This is blank")
```

Which, if the first argument results in a blank, returns the second argument.

Thanks

You could build your special VLookup function

```
Option Explicit
Public Function MyVLookup(Arg1, Arg2, Arg3, Optional Arg4 = True)
MyVLookup = Application.VLookup(Arg1, Arg2, Arg3, Arg4)
If VarType(MyVLookup) = 0 Then MyVLookup = vbNullString
End Function
```

But possibly using a VBA user definde function is slower than using this method `=if(vlookup(args) = "", "", vlookup(args))`

I could imagine (would need to be tested).
