Hello @jm.zhang
Sorry for the late reply,
Could you please reproduce the two scenarios:
-

-
upload the xls file to the portal,
Next, send us the Document Server and Community Server logs, also tell us which guide you used to install the Workspace
In case of problem with uploading the CSV file, please send it to us
Also please do not duplicate threads with the same issues - Tip: error occured in the document service(error code = -7)
