I am having a Power BI report application developed in Power BI Desktop and it is using an Excel file from my local machine as datasource. I have published this report to Power BI Online (to the client) and then how can we update the excel data in Power BI online.
Please make changes as you required in Excel file and then republish to power bi online service . You will have updated data source in power bi Online. Pls reply if you find any query while refreshing.
