Hi Matias, thanks for raising this idea, as mentioned on our Facebook Page last week we are working on Google Sheets integration with our Scheduled Export engine. When it’s ready it will be announced on the Blog here 🙂
Regarding your query about how secure saved exports are (by default Settings > Enable Archives is turned off), we generate a unique export filename which makes it particularly tricky to guess the filename of saved Media, here’s our default format:
export_%export_type%-%year%_%month%_%day%-%hour%_%minute%_%second%-%random_key%.csv
This has been checked over by WordPress security experts as the best way to minimize exposure of saved exports, in a future Plugin update we will move exports to a dedicated directory within the WordPress Uploads area which will allow us further control access. You can use the “Save to this server” export method within Scheduled Exports to save exports to a directory with limited access (either using .htaccess or .htpasswd)
