Any document with more than a certain size will be opened in the Large File view of JSONBuddy. You can set the size limit in the settings of the application. The screenshot below shows the editor after loading an original OSM document with the geographical information of Massachusetts. JSONBuddy was also used to convert the OSM data to JSON.
