Hi Kavish vaidya ,
When you download any file from a source in microsoft power automate, you will get a binary or encoded string. (Later this string can be used to convert this the file type of pdf, excel etc by converting it to base64 format)
if I understand your requirement currently, you want to be able to read the data from excel you downloaded and create the records using that data in dynamics?
if I am correct, I would recommend you move this file first to sharepoint or one drive and from there you can read rows using the excel connector and perform actions.
to save this one drive or sharepoint, see below :powerusers.microsoft.com/…/444658
