excel如果a列中的名称与b列具有相同的日期，则将c列中的所有结果相加

Question

I've been having a problem that I can't seem to solve fully. Basically, I have a range of data that looks like this.

START DATE(UTC)      DURATION (mins)     NAME
--------------------|-------------------|------
5/08/2018            5                   Home
5/08/2018            1017.616667         Home
5/08/2018            493.9166667         Sleep
5/08/2018            19.6                Mindfulness
6/08/2018            8.55                Transport
6/08/2018            115.1333333         Gym
6/08/2018            12                  Transport
6/08/2018            6.483333333         Home
6/08/2018            6.75                Home
6/08/2018            1170.716667         Home
6/08/2018            510.2166667         Sleep

My goal is to collate the durations that have a matching name and occur on the same date and then apply a formula to a largish data set. So I should be able to get 1022 for "Home" for the 5/08/2018 and 1184 for "Home" on 6/08/18. I've tried a sumif but only managed to add up all those that occurred within 30 days.

Any help with this would be awesome

Thank you

You could use a pivot table: Insert > Pivot Table . Put Name into the Columns field, Start Date into the Rows field and Sum of Duration in the Values field.
