## Identify missing numbers in a range in excel

**Question:** How do I find missing numbers between 1-9 in a range?

1 3 4

5 6 7

8 8 3

**Answer:**

**Array formula in cell B8:**

If you have numbers between 5 and 32, change ROW($1:$9) to ROW($5:$32)

The formula won´t work if you have numbers above 1048576 (excel 2007). See this post:

I have a worksheet that has rows, each containing sequential groupings of values of "1" and "0" These alternate across 1800 colunms of data.

My question: how do I count the number of groupings of each? In other words, across those 1800 columns, how many arrays of value 1 and how many arrays of value 0 do I have?

Thanks.

Joe

Joe,

see this post:

Count the number of groupings of each value

Is there any difference to apply this formula in only one column (F2:F1093)? I´m trying to identify missing numbers in a list but I´m making something wrong.

Felipe,

Did you enter it as an array formula?
