Dear fellow members,
My apologies for wasting your time and brain power, however the use of
Calc and VLOOKUP is NOT the right tool for the job and that INDEX(MATCH)
would have ben better, given that the downloaded .csv data file grows by
approximately 1MB per month.
I have marked this thread as closed and shall be starting a new thread
as I move the data file to Base. Expect the Base questions soon 0:)
Apologies again
Thank-you

Hi,
Using LO Calc 7.3.2.2 and I have a 28 column table RAW Data table in
excess of 65k rows. A three column sample below:
Date Simple Date Outdoor Temp
2022-01-01T00:05:00+02:00 2022-01-01 00:05:00 17.5
2022-01-01T00:00:00+02:00 2022-01-01 00:00:00 17.4
I have a secondary table, called Amended RAW Data containing just the 10
digit date and the corresponding value of the column value I am seeking,
whether it be the Outdoor Temp, Daily Rainfall etc
What I need to do is query the following table, searching for a specific
10 digit date, and find the max value on a specific date.
I have tried so many different itinerations on the VLOOKUP formula and
browsed many elementary Google VLOOKUP pages that I need help. I have
tried(all return N/A):
=MAX(VLOOKUP(LEFT($'RAW Data'.$B$2:$B$62037,10),$'RAW
Data'.$B$2:$L$62037,1,FALSE))
=MAX(VLOOKUP($A11,$'RAW Data'.$B$2:$M$62037,11))
=MAX(VLOOKUP($A11,$'RAW Data'.$B$2:$M$62037,11))
=MAX(VLOOKUP(LEFT($'RAW Data'.$B$2:$B$62307,10)=$'Amended RAW
Data'.$A$11,$'RAW Data'.$B$2:$L$62037,11,0))
References to 'Amended RAW Data'.$A$11 refer to a date that I know has
greater than zero value, and the 11th column data I want to max, within
a date.
Help appreciated
