Hi. I have a JSON formatted file, but its file extension is .config, not .JSON. How do I view a .config file in the JSON manager? If I rename the file to FileName.JSON, then the JSON Manager recognizes it and I see the tree view and so on.
You've answered your own question.
When called by a computer program, the calling program assumes that the provided file is in fact a JSON file and so doesn't care what it is named. Thus there is no restriction on what extension may be used for a JSON file. However for a programmer's text editor like UltraEdit there can be no assumption that any file contains JSON in it without being told. The identification method that the authors of UltraEdit selected was to use the case-insensitive extension .json and when this is used the JSON specific features are activated.
This is a user-to-user forum not normally monitored by UltraEdit staff. You can request a feature change to allow the user to specify that a file is JSON instead of automatically by the extension. Go to https://www.ultraedit.com/support and fill out the form at the bottom of the page. Code change priorities are driven by number of user requests. It may take quite a while to get enough support for a change.
