Copy of empty cell gives false on ISBLANK

A1 is empty ISBLANK(A1)=TRUE

A2 =A1 then ISBLANK(A2)=FALSE


This is not expected is there a solution?

Hi bmmj


Tested in Numbers (and I assume it will be the same in Excel).

Instead of ISBLANK, use a formula to see if a cell is equal to "" (NULL)


Formula in B2 (and fill down) is IF(A2="","NULL","Not NULL")

Formula in A3 is =A2 Also NULL.

A5 contains a space character. It displays as blank, but it is Not NULL.

Ian.

Remember that 'empty' is not the same as 'blank'.


That is, if you place a space character, say, the cell is not blank. If you erase the cell, then it will be blank. Whether cutting and pasting in a Numbers/Excel/Quattro/Calc spreadsheet, this holds true, and it's easy to copy a blank cell from one place to another where it matters. What result do you get if you COUNT empty cells for that range?
