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
Use conditional formatting (Home tab, styles section) and apply highlight cells rule (putting 0 in the Format cells that are equal to box) but select custom format then the Number tab. Select Category custom and in the type box put:
0;-0;;@
Sounds complicated but is actually simple.
This gives the advantage that the cell looks empty but 0 is still the underlying value, so any formulas you use against that cell/selection will still see it as being numeric and saves on lots of messing around with chained IF statements.
