Convert sub to json

What is the difference between .sub and .json?

Description: MicroDVD is a subtitle file format for digital video. Its name is derived from the MicroDVD Player, a media player application designed to play DVD videos along with subtitles, originally developed by Tiamat Software. The application was first released in 2000 but development ended in 2001. Media players that support the format are able to interpret MicroDVD subtitles and mix their contents with their corresponding video files.; A JSON (JavaScript Object Notation) file is a lightweight, text-based, human-readable format used for data interchange. It is designed to store and transport data. JSON files use the .json file extension and are structured as a collection of name/value pairs, where the names are strings, and the values can be strings, numbers, arrays, or even other JSON objects. This format is widely used in web applications for exchanging data between a client and a server, as well as in configuration files.
