I have multiple json files with different payload and I would like to run them using collection

I have multiple json files with different payload and my endpoint doesnโ€™t accept files. I need to use collections to run the files but it is accepting only one file. Is there a way I can run all the files one after other in a single go.

Can I use excel and give the json path in file and place all my files in working directory and run them?

Please help!!
