Sum of large minute/second figures

[Guest]

I'm trying to total a column with large minute values. For example, I want
to add 0:1125325:27 (1,125,325 minutes, 27 seconds) with 0:2358964:18
(2,358,964 minutes, 18 seconds. My total column shows as 00:00, no matter
how I play with the format. I have the individual times formatted as
h:mm:ss, and I have the total column formatted as [mm]:ss so the results will
stay in minutes. However, it's almost like I need to have h:mmmmmmm:ss and
[mmmmmmmm]:ss. However, that's not working for me. If I try to create
h:mmmmmmm:ss, Excel saves it as h:mmmm:ss, and then it reads the 'm' as
month instead of minute. I'm not getting anywhere. If anyone knows how to
make
this work, I would really appreciate it.

Thank you!

The largest number that can be entered directly and interpreted as a
time is 9999:59:59 or 599999:59 in [m]:ss. The largest number of minutes
entered in h:m:s format is similar: 0:9999:59. So your 0:112535:27 is
likely not being parsed as a time, but as Text.

Much larger values can be displayed. For instance, a million hours

=1000000/24

will display as 60000000:00 when formatted as [m]:ss

So if you want to add values that have the number of minutes >=10,000,
you'll have to use string manipulation:

=MID(A1,3,FIND(":",A1,3)-3)/1440

formatted as [m]:ss gives 1125325:27. Do the same with your other
values and you can use SUM() to sum them.

Excel is not seeing the values as h:mm:ss because there are too many digits
in mm. It is seen as text. The formula below will do your calculation, but
the result will again be text.

=VALUE(MID(A1,3,LEN(A1)-5))+VALUE(MID(A2,3,LEN(A1)-5))&":"&VALUE(RIGHT(A1,2))+VALUE(RIGHT(A2,2))

This assumes your original data is in A1 & A2
