What Does It Do?
This function will determine if there is an entry in a particular cell. It can be used when a spreadsheet has blank cells which may cause errors, but which will be filled later as the data is received by the user. Usually the function is used in conjunction with the =IF() function which can test the result of the =ISBLANK()
Syntax
=ISBLANK(CellToTest)
Formatting
Used by itself the result will be shown as TRUE or FALSE.
