In Excel, I have conditional formatting that changes the colour of the cell when the formula is removed. =NOT(ISFORMULA(cellnumber)) is the conditional formatting. The formula in the cells is linked to another excel sheet and uses data from that excel sheet. When I break the links from the excel sheet, all of the cells change color because of conditional formatting. I want to break the links, but I don't want all of the cells to change colour. I only want the colour change what was before breaking the links.
