In the further part of this page we have added a list of programs that should open your JSON file. It is enough you choose a proper application for your operating system, download and install it.


JSON files are called JavaScript Object Notation files. It is a data format designed for easy data exchange between different applications.

JSON files are simple text files that can be opened in any text editor. Larger files can be quite confusing, so it is recommended to use a JSON editor.

JSON files are often used in Ajax applications as an alternative to XML files. Although JSON is mainly used by web applications, it is also used in other applications such as Mozilla Firefox, Google Chrome, Mozilla Thunderbird or Caliber.

How to open a JSON file? Advice and guidance

Absolutely most often appearing reason that prevents you from opening the JSON file is the lack of a proper application to support it in your operating system. It is notably the first thing you need to address. When one of the programs to support a JSON file from the list is already installed, you can try to rerun the file. The system should display a message asking you to choose a primary application to support JSON files. At this point we are looking for disk space where the application was installed in and we can link it with a JSON file. Since then, our operating system will use the selected program to support all JSON files.

Other issues

Despite the described problem with JSON there may be many more problems. If the existing operations were not effective, get involved with the following matters:

- verify that the JSON file is not damaged and that it has been downloaded or copied in whole
- verify that the file has a file extension that has not been intentionally changed (for example, if it do not contain other information than its extension suggests)
- make sure again whether the JSON file type is linked in the operating system with a proper program
- make sure that the file is not infected with a virus and you have up to date software and drivers.
