Macro that will sum values from column if rows meet certain criteria [better sumif]

Hi,

I want to create a macro which will make new file that will contain data from other file. While my English is bad and I really can't explain what I want, I hope that this picture representation will show what I mean.

I have this file (NAZWA means NAME and Wartość means VALUE):

And after running the macro, I want to have this new file:

Thanks in advance for every response!


PS. SUMIF is not the way, as files are much, much bigger than those in example.
