What is a .JSON file?

JSON files are data files that store plain text in the JavaScript Object Notation (JSON) format and are typically used for lightweight data transmission. While humans can read the JSON data, the files are most often used for communication between applications, such as a web application and a server. JSON is a popular alternative to XML and has replaced it in many contexts for lightweight data storage and data interchange.

JSON files are most often encountered by software and web developers, but you may also encounter JSON files as an end-user of various software programs. For example, the web browser Mozilla Firefox saves and transfers bookmarks using JSON files. File Viewer Plus can be used to open, edit, and save JSON files. The program provides various viewing features, including a syntax tree view, word wrap, code folding, ruler, and line numbers.
