at the moment, I have a very large spreadsheet (40k+ rows), the data includes columns for “name”, “date” and “value”. the format is uniform.
I want to be able to sum all “values” with the same “name” and “date”.
E.g.:
Name date value
peter 201103 7
pan 201103 9
felix 201104 9
peter 201104 12
peter 201104 17
Now, I want to sum the value for all “peter” with date “201104”.
One approach is SUMFS but that is not at my disposal (using excel 2003 only).
Another thing I tried is to first filter via inputbox autofilter for the date and then use SUMIF to sum the values if they have the same name. PROBLEM: SUMIF also adds up the invisible cells.
Best would be a vba approach.
Has anyone an Idea? It would be of tromendous help!
Thank you for your time!
Do a pivot table. Then use the Page as a filter for Peter and 201104. That’s the fastest way to get to the answer.
