It is possible in MS Flow.
Steps-
1. Your MS Form is ready i hope so.
2. Use trigger action when new response summited (MS Form Trigger).
3. Use "Get response details" Action and supply Form ID and Response ID.(These dynamic content come from trigger).
4. Create an excel sheet with formatted as a table (select all required columns and then do formatting)- Excel connector requires data inside table.
5. Upload that excel file either in One drive or SharePoint library.
6. Now Use "Add row in to a table" excel connector: select location-one drive/ SharePoint site, document library , file and Table.
7.Add dynamic content from "Get response details" in each column of excel sheet.
8. Now you excel is ready.
9. if you want notify someone with this excel you can automate email notification.
Let me know if you need any other help.
Thanks
