Falt File connection


I know how to made connection of flat file with Power BI. Is it possible to automate updated flat file in Power BI for making Reports. For example : I have a requirement like  flat file will come in daily basis, so on this basis the report get updated automatically based on updated flat file.


Also, based on above requirement is it possible with REST Api?


Thanks in advance.

Hi @Blad_123


You can create a folder to contain these history file and updated file, then connect to this folder in Power BI desktop and use Combine Files feature. Please make sure file type and structure of these files are the same. Then you can click on Refresh in Power BI desktop or set schedule refresh for the dataset in Power BI service to get updated data. See:
