I have a file with abcd.json extension which is inserted in form-data body with the header Content-Type:multipart/form-data and Accept:application/json. I want to convert this abcd.json file to raw json so that it can be posted in the raw body. I tried using Content-Type:application/octet-stream but it is not working. I tried using the body as it is. This is the data inside abcd.json file
