Counting Incrementing/Decrementing in Google Sheets using Arrayformula & Countif
Hi As seen in the image, I have a column of numbers that keeps growing at the bottom.
I need the column C to have a Decrementing counter for how many times the number in column A has occurred so far in that column A. Its working fine if I drag the Countif formula manually like in column D each time a new number is added in column A, but I need it to work automatically with Arrayformula.
Similarly, I need the column C to have a Incrementing counter for how many times the number in column A has occurred so far in that column A. Its working fine if I drag the Countif formula manually like in column F each time a new number is added in column A, but I need it to work automatically with Arrayformula.
Here is the link to the google sheet as example: https://docs.google.com/spreadsheets/u/2/d/1jCNXBvoxHL9ykUD9CAeyBb14Z9R7NfSkIumHg_CHfTk/edit?usp=sharing
Here is what I found: https://www.labnol.org/internet/arrayformula-copy-formulas-in-entire-column/29711/
I'd greatly appreciate your help.
