To export data from your Vendr account, navigate to the table you wish to export and click the 
symbol at the top-right of the table. This will export said table into a .csv file.
For exporting detailed data (eg., documents associated with a specific workflow), you'll need to click into that workflow and then download the individual document you'd like.
If you would like a complete export of all of your files, click "Talk to a person" over chat or email with Vendr Support.
