Hello folks
I've been creating a workflow to send out files to ~500 employees but the email tool doesn't like to have the layout as an attachment; I get the following error:

It's quite a long error being a page and a half in Word.
I've tried a very simple workflow of Input > Basic Table > File Output and on those files the error appears in the Excel file in one of the columns.
I thought maybe my data was corrupt so created a new file and am still having the same issues.
Many thanks
