How to sum entries that have same ID OpenOffice - Calc

Question

I have a spreadsheet similar to the one in the screenshot.

From this I want to sum all the entries in Data 2 which have the same Data 1 ID and store it in another column. So something like this:

I am not able to figure out the formula which would do this. I figured out how to get a column with unique entries I just need to figure out how to get the sum of the values which have the same data 1 id.

Can someone point me in the right direction?

Answer 1

You can use SUMIF, e.g. if I'm reading your sheet right, =SUMIF(A$2:A$7, A11, B$2:B$7), and then copy down. This sums the values from B2-B7 whenever the corresponding value in A2-A7 matches A11.

You can find more on SUMIF here.

Answer 2

you may use subtotals function under the Data tab, although it gives you the answer in the row below all the cell matching your id; then you have to click the - and + buttons that appear on the left...you may see these in this picture of my data this is a nice resource when you have non-English characters(á, ó, ß,...), spaces, dashes and points, so it becomes difficult to process with sql
