Hi,
I am quickly losing patience with a task that requires a sum of values
that occur on the same date, but at different times.
My raw data sheet is in 4 columns
Date/Time | Value 1| Value Y| Value z
2021-10-08 08:00:00| 5| 7| 0.15
2021-10-08 14:05:16| 3| 10| 5
2021-10-09 10:05:30| 15| 3| 25
2021-10-09 18:00:00| 15| 9| 6
...
[...]
I'd really appreciate some pointers here, even if not possible. If not
possible what could be done. I just don't understand the
INDEX(MATCH())/vlookup argument.
A date-time is a floating number. The integer part being the date (from
a reference day -- 12/30/1899 is a standard), the decimal part being the
time (0.0 for OO:OO to 0.9999999... for 23:59:59...)
Thus it's no suprise that SUMIF and its siblings won't find a date.
-> Did you try querying on the INT() value of the date-time, which is
the date part?
Best,
