I am using the following formula in a Google spreadsheet to calculate the number of days between two dates (dates are in columns G and AL). The problem is that some of the cells in col AL are blank, so the formula is reading those dates as something else and returning a very large number. Also, when both cells are blank, the formula returns a
0, messing up my data. How can I include something to ignore blank cells or just return a blank when one or both cell references is blank?
Here is my formula:
=ARRAYFORMULA(if(row(A:A)=1, "Readmission Days", (G:G)-(AL:AL)))
PS: The formula has to be an array because I am working with a Google form and entries are automatically populated into new rows.
