Thank you @GilbertQ! However, this is not my scenarion.
I am using 'export' functionality to export data from an online PBI report to an local excel file, then expecting any data change (For example, the online dataset auto-regular-refresing retrieved fresh data from data source to the dataset/reports) can also be refreshed/pushed to the excel file.
The PowerBI Publisher for Excel you introduced is seemingly same to the "Analyze in Excel" menu/functionlauity of online PBI reports that create pivot or chart in excel using the PBI data as data source. But my scenarion is directly using/presenting existing report's data(items) in excel(I don't create pivot or chart in excel file).
