I am trying to count number of IDs that exist as of a particular date (see Summary tab). However, since the dates (column A) in raw data tab are in UTC timestamp format, the formula returns 0.
My formula is countif('raw data'!A:A,"<="&A2)
- How do I adjust the formula to convert UTC timestamps to datevalue within countif function.
- I also would like to make this countif function work with arrayformula so that I don't have apply the formula on each row. Here is the sample sheet : https://docs.google.com/spreadsheets/d/1IFAAiguhKD0xK8SYsnzMBSar4IFAQPzZfIh0U44bZWI/edit?usp=sharing
