- where is value to check with the function.
The can be any type like empty cell, Boolean values,text,non text,number,reference-value or name referring to any of these.
- This function will give the result as either TRUE or FALSE according to the value.
- This function will not convert to numbers from text.
- Function will consider as string if its written in quotes("").
