doc increment value changes 1

Supposing, you have a list of values in column A, and now you want to increment number by 1 in column B when the value in column A changes, which means the numbers in column B increment until the value in column A changes, then the number increment starts from 1 again as left screenshot shown.

To increment numbers based on another column when value changes, the following simple formula may help you.

1. Enter this formula: =IF(A2<>A1,1,B1+1) into a blank cell which beside your data, B2, for instance, see screenshot:

doc increment value changes 2

2. Then drag the fill handle down to the cells that you want to fill sequence numbers and restart for every change in column A, see screenshot:

    is there a way to do this but I want to separate the different numbers, for example like
    A1 1
    A2 1
    A3 2
    A4 3
    A5 3

    I would like to automatically calulate the maximum number 1 in a row, maximum number 2 etc
