Hi! I am a developer with experience working with REST API and I can help you with this. Please contact me so we can discuss your project!

Im a 7 year experienced java developer. Bidding for low price to get a good reputation to star with. Quality work assured.

Being a computer science undergrad and quite experienced in using API with Java, I can assure you quality work within less time.

the requirements are ok. but you cannot hit any rest API and get the json converted, 1. the server need to return json.2. every api has either get or post method and parameters might be different for get and post data for post. for nested hierarchy of data you cannot get it as csv. if it's primary data types it works. for nested it won't work out. we can discuss on chat to understand more, before we finalize

I have good understanding with Jackson to convert Json to Java Object and Apache POI for XLS Files. I have previously written this kind of program for my previous employer.

I can provide you a general solution in Java for calling any Rest API. And saving the response can be built as per your requirement. Thanks
