Hello Nikhil,
thanks for your reply.
This is the Link that includes the explanation about the different Reports and how to get them via API. I have already extracted Audit Reports Via API and in that case it is possible to get the data in csv format (screenshot).
However for the campaign Performance Report this is not possible (I have tried). In the documentation the following is stated:
Parse the Query Response
Optionally, you can use a scripting language such as Perl, Python, and Ruby, to parse the results and write them to an output file, such as a CSV file, that you can view in any spreadsheet application.
As I mentioned before I don't know any of those Languages and yet I would like to distribute the report in excel format. Any help would be appreciated.
Thanks,
Ivan
