Opening JSON files

Did your computer fail to open a JSON file? We explain what JSON files are and recommend software that we know can open or convert your JSON files.

What is a JSON file?

JSON stands for Java Script Object Notification. Files that contain the .json file extension are similar to files that use the XML file format. The JSON file format is used to transmit structured data over various network connections.

The .json file extension is also used by the Firefox Internet browser, which is distributed by Mozilla. The Mozilla JSON files contain a backup copy of the bookmarks that have been created by a user who is using the Firefox Internet browser. If a user somehow loses his or her bookmark information, they can recreate the bookmark data using the information found in the JSON files.

Try a universal file viewer

In addition to the products listed above, I would suggest that you try a universal file viewer like Free File Viewer. It can open over 200 different types of files - and very likely yours too! Download Free File Viewer.
