Have Excel formulas that return 0, make the result blank

Question

A recurring Excel problem I have is formulas such as INDEX(array,row,column) that return 0 when there\'s no result, rather than returning blank.

What is

Answer 1

Just append an empty string to the end. It forces Excel to see it for what it is.

For example:

=IFERROR(1/1/INDEX(A,B,C) & "","")
