Why does #NULL appear in Excel?

The #NULL error occurs when you use an incorrect range operator in a formula or when you use an intersection operator (space character)  between range references. The #NULL error specifies that the two ranges do not intersect.

How to fix the #NULL error in Excel

Follow the methods below to fix the #NULL error in Excel:

1] Insert a Colon

If you are using a space in your formula or an incorrect operator, for example, =SUM(A2 A3), Excel will return the #NULL error.

To fix this issue, you should use the colon to separate the first cell from the last cell, for example, =SUM(A2:A3).  The colon is used to separate when you refer to a continuous range of cells in a formula.

2] Insert a Comma

Excel will return a #NULL error when you refer to two areas that do not intersect, for example, =SUM(A2:A3  B2:B3).

If the formula sums two ranges, make sure that a comma separates the two ranges =SUM(A2:A3, B2:B3).
