What is the ISBLANK Function?
The Excel ISBLANK function is categorized under Information functions. It helps
extract information from a cell. ISBLANK checks a specified cell and tells us if it
is blank or not. If it is blank, it will return TRUE; else, it will return FALSE. The
function was introduced in MS Excel 2007.
In financial analysis, we deal with data all the time. The ISBLANK function is
useful in checking if a cell is blank or not. For example, if A5 contains a formula
that returns an empty string “” as result, the function will return FALSE. Thus, it
helps in removing both regular and non-breaking space characters.
However, if a cell contains good data, as well as non-breaking spaces, it is
possible to remove the non-breaking spaces from the data.
Formula
