Creating Connection in model stuck

Hi Anonymous 

First, please tell me some basic information:

Do you connect to excel files with power bi desktop?

Is the data in excel file from outside source?

To end the refresh process, please open task manager, find the "Microsoft Mashup Evalution", this is the process for connecting in power bi, end the task of this.

In Power bi desktop, to improve the performance when connecting, please turn off options below in Options and Settings->Data load:

'Relationship","Time Intelligence","Backgroud data","parallel loading of tables".

Besides, please check if any blank column from excel(your data source) is loaded into Power bi.

Best Regards
