How can I use a google sheet formula to determine whether a cell contains an image? I don't mean cells that have formulas such as =image(url), but rather cells that have just an image imbedded in the cell.
I've tried many things (=isText(), =isNumber() =isFormula(), =isNA(), =isURL(), =isBlank(), =isNonText()), but the closest I've been able to come up with is to combine isNumber() and isNonText() within an XOR(). However, as shown in the animated .gif (where A1 is a blank cell), this doesn't distinguish a cell containing an image from a blank cell.
