Restart row count each time the value in a specific column changes
 

Is there a formula that will restart the row count when the value in a
specific column changes --- such as shown below when the value in column A
changes the row count in column B restarts?

A B
1 452 1
2 452 2
3 452 3
4 452 4
5 329 1
6 329 2
7 548 1
8 548 2
9 548 3

Thanks in advance

Answer: Restart row count each time the value in a specific column changes
 

1. Insert a new column next to column B (let's say it's column C).
2. In cell C1, enter the formula: =IF(A1<A2,1,B1+1)
3. Drag the formula down to the last row of your data.
4. Column C will now display the row count that restarts each time the value in column A changes.

Explanation of the formula:
- IF(A1<A2,1,B1+1): This formula checks if the value in cell A1 is different from the value in cell A2. If it is, it means that the value in column A has changed, so it resets the row count to 1. If it's not different, it means that the value in column A is the same as the previous row, so it adds 1 to the row count in the previous row (cell B1).

Here's one ..
In B1, copied down: =COUNTIF(A$1:A1,A1)
