I'm using Excel with Workspace and Datastream. I have many files that I want to update via the excel addin. I want to write a code (VBA or Python) to open these files and "click" "Refresh Worksheet" button, wait for the update, and then save and close the excel files. Could you assist me with a short code snippet that would tell Workspace toolbar to "Refresh Workbook"? (either in Python or VBA) Also, is there any programatic indication that the update has finished, i.e. the data request has been completed? So that I know when can I save/close file or perform additional operations
