This error occurs when alfresco try to generate thumbnails for this Office documents.for xlsx it will use apache poi library to extract thumbnail from OOXML file，if you upload it as an xlsx file but in fact it is not an xlsx file(for example xls file),poi can't handle it.

Exception like following will be thrown

Caused by: org.apache.poi.openxml4j.exceptions.OpenXML4JRuntimeException: Fail to save: an error occurs while saving the package : null

As kayne zhang said, have you tried to change the Mimetype for this content after the upload?

Thanks Zhang for your reply, We asked the content editor to edit the excel in their common platform (eg. google sheets) which will avoid this error and we tested it works perfectly.
