How to get total sum of data in a column format dd:hh:mm

If I understand correctly, you're looking for a way to sum the time values within a column that are currently formatted to show dd:hh:mm. I broke it down by converting each section to minutes and then extracting the amount of days, hours and minutes in the final "minute sum".

This beast mode seems to work in my testing. Just replace the 'Time' column throughout the code with whatever column you are wanting to sum. Hope this helps!

CONCAT(
FLOOR(SUM(SUBSTRING(`Time`,0,INSTR(`Time`,':'))*24*60
+
SUBSTRING(`Time`,INSTR(`Time`,':')+1,INSTR(`Time`,':'))*60
+
RIGHT(`Time`,2))/1440)
,':',
FLOOR((SUM(SUBSTRING(`Time`,0,INSTR(`Time`,':'))*24*60
+
SUBSTRING(`Time`,INSTR(`Time`,':')+1,INSTR(`Time`,':'))*60
+
RIGHT(`Time`,2))-(FLOOR(SUM(SUBSTRING(`Time`,0,INSTR(`Time`,':'))*24*60
+
SUBSTRING(`Time`,INSTR(`Time`,':')+1,INSTR(`Time`,':'))*60
+
RIGHT(`Time`,2))/1440)*1440) )/60 )
,':',
SUM(SUBSTRING(`Time`,0,INSTR(`Time`,':'))*24*60

SUBSTRING(`Time`,INSTR(`Time`,':')+1,INSTR(`Time`,':'))*60

RIGHT(`Time`,2))
-
(FLOOR(SUM(SUBSTRING(`Time`,0,INSTR(`Time`,':'))*24*60

SUBSTRING(`Time`,INSTR(`Time`,':')+1,INSTR(`Time`,':'))*60
