jsonlite is known for its high performance. It is written in C and offers a fast JSON parser. This makes it suitable for working with large JSON datasets.

While rjson is generally considered slower than jsonlite, the difference may not be significant for small to moderately sized datasets.

In this article, we will see How to read a JSON file in R through an example, and also we will have a look at how to convert JSON data into a data frame. As we know, in the R language, we have to install different packages to deal with other things, so the first step is nothing but installing the package rjson.
