Why Information Formulae ? Excel's Information functions gives you information

about the data in a cell or range of cells. This information includes whether the data is a number, the formatting applied to the cell, or even if the cell is empty.

Each of these functions, referred to collectively as the IS functions, checks the type of and returns TRUE or FALSE depending on the outcome. For example, the ISBLANK function returns the logical TRUE if is a reference to an empty cell; otherwise it returns FALSE.

ISEVEN() N() TYPE() IS EVEN()

Important The "IS" statements only take one cell at a time,

but not a range.

For Convenient Reading each formula colored differently

the "IS" statements only take one cell at a time.

ISBLANK() This Formula returns TRUE if the reference Cell is Blank . This formula is useful to find blank cell in a large range of Cells

In other words - the IsBlank function can be used to check for blank or null values

In this Example , in Case of A1 , the result is False since A1 is not blank , where as B1 is Blank

Using ISBLANK Function with other Formulae=IF(AND(ISBLANK(A1),ISBLANK(B1),ISBLANK(C1)),

”This Cell is Blank”,False)

In the above Formula , we can find out , by using IF Formula with “And” Criteria , to notify Blank Cells from the large Range of Cells.

Using ISBLANK Formula in Conditional Formatting

In this example , I have tried to know how many Cells in the range of A1 to E2 are blank

Procedure, As shown in the picture, I have opted Conditional Formatting-> Highlight Cell Rules->More Rules ->New Formatting Rules. Then I have opted for “Use a formula to determine which cell to format.I have used Formula =NOT(ISBLANK(A1:E2)) and selected the CELL FILL to be RED). In this Case If any cell contains single space also, it will be indicated with RED Fill.

ISERR()In Excel, the this function can be used to check for error values. In other words , This function, Is Error Other Than Not Available, tests whether a value, an expression, or contents of a referenced cell has an error other than not available (#N/A)

Using , ISERROR with other formulae ( better usage of ISERROR)

In this case, Search for a Name listed in the range F3:F11, within the range B3:B11. Return the Overtime for that name, listed in range C3:C11, and place the Overtime , in range F3:F11

. If we deleted any name from range B3 to B11, the result in F3 to F11 would be #N/A in respective cells because, the formula would not be able to find the name in range B3:C11. To hide the error value, the formula would be:

=IF(ISERROR(VLOOKUP(E3,$B$3:$C$11,2,FALSE)),"",VLOOKUP(E3,$B$3:$C$11,2,FALSE))
