Is it possible to have subscriptions sent as a ".CSV" attachment instead of a ".XLS"?
If so, where does this setting get changed?
By subscriptions, do you mean Smart List subscriptions? You can change the format by selecting "Comma Separated Value" as the "Format" type when setting up the subscription.
Sorry, I am referring to "Report Subscriptions" in the Analytics section of Marketo.
As far as I know, you can't change the file type for Report Subscriptions. What is the reason for needing a .csv instead of .xls?
The reporting platform we use accepts emails with an attached .csv as a data source... It does not accept .xls.
