If you want a formula that inserts a text, instead of leaving blank cells, you can use the ISBLANK function. This function returns **TRUE** if a referenced cell is empty or **FALSE** if it contains any other value.

Here’s how it works.

In this example, only **B4** returns **TRUE**. **B2** returns **FALSE** because there is a space inside cell **A2** which is not visible here.

Now, if we connect ISBLANK function with the IF function we can decide what will be displayed inside the cell.

We are going to use the following formula.

=IF(ISBLANK(A1),"Blank",A1)

**Formula explanation**

If cell **A1** is blank, display the text “Blank”, otherwise display **A1**.

Now, if you look at our modified example, you will see that it copies all values from the left side of the formula. Only one cell (**B4**) displays blank as the condition is met.

Maybe you would like to modify this formula to also display “Blank” in cell **B2** where there is a space.

=IF(OR(ISBLANK(A1),TRIM(A1)=""),"Blank",A1)

**Formula explanation**

The TRIM function removes all leading and trailing spaces from a cell. If you have only spaces inside a cell, it will remove all of them.

The OR function returns TRUE if any of its arguments is **TRUE**. In other words, it returns **TRUE** if a cell is blank or a cell equals “”. Cell **A2** meets this requirement that’s why it returns “Blank”.
