My goal is to send Excel file from client using the URL to server. Then, server will process and check all records within the Excel file and correct records according some rules. After that, the new updated Excel file must be returned to client in Jason or XML format.

Hi! Thasnks for the question. So far I am not sure where is WireMock's place in this use-case. Are you trying to mock the file server's API and test your client?

No, actually, I need the client to use a URL to send a file from local device to server using the API. Then after server finish processing the file, the server will return the file to client again, is this able to be done over WireMock framework ?
