What is OData in JSON?

What is the need of OData?
OData helps you focus on your business logic while building RESTful APIs without having to worry about the various approaches to define request and response headers, status codes, HTTP methods, URL conventions, media types, payload formats, query options, etc.
Is OData same as JSON?
OData is a similar specification to JSON API. Both of them describe a standard protocol for creation and consumption of RESTful APIs. GraphQL is a totally different approach to API design and specifies a different way of querying API resources.
Is OData REST?
ODATA is a special kind of REST where we can query data uniformly from URL. REST stands for REpresentational State Transfer which is a resource based architectural style. OData is a web based protocol that defines a set of best practices for building and consuming RESTful web services.

The Open Data Protocol (OData) is a web protocol that is designed for querying tabular data and provides you with an alternative to SOAP-based web services. OData uses URIs for resource identification and commits to an HTTP-based, uniform interface for interacting with resources.
Which is the best version of OData to use?
OData Version 4.0 is the current recommended version of OData. OData V4 has been standardized by OASIS and has many features not included in OData Version 2.0. OData supports two formats for representing the resources (Collections, Entries, Links, etc) it exposes: the XML-based AtomPub format and the JSON format.
