If you're looking for a way to do this through API, then there isn't. I mean, our REST meetings APIs do return the data in JSON format, which can then be imported into excel as a CSV file I believe (doesn't happen directly, you would need to check online for how to do this) but we don't have a direct way to do this through APIs.
Probably the best way for you to achieve this is to create a report through Control hub that takes all this data, and then export it as an excel file. I do not know the exact report to use but should be possible. You may check this further with your Org Administrator, or reach out to the TAC team on help.webex.com/contact to get further assistance on this.
