Hi there,
In case you use Outlook, you could consider using the action under Outlook -> Retrieve email messages from Outlook. This action, among others, offers the ability to select whether you want the attachments saved.
By selecting the option "Save Attachment", another field will show up asking for the extraction path.
You may then use this path to access the excel file using all the given actions you will find under the Excel actions folder.
Thank you for providing your feedback. Please let me know in case this works for you 🙂
Georg
