Something I run into a lot is a JSON-like blob of text I'd like to be formatted as JSON (new lines and indentation). Most JSON formatters choke on improper JSON (understandably). It would be great to have a tool that was more lax. Like browser support for terrible HTML lax haha. If I could paste JSON-like strings into a text area and have it fix and format it as best as can be, that would be great. Some examples of non-JSON syntax to handle would be like single quotes instead of double, arbitrary JSON nodes (not necessarily wrapped in `{}`), some pre or post text (some non-JSON text at the beginning or end), comments amongst the JSON, etc. Another JSON aspect that would be useful is something to escape/unescape JSON (specifically double quotes). I deal a lot with JSON that includes escaped JSON in values and it would be great to have some better way to visualize and process those blobs. Sublime Text has a nice plugin to handle some of the escaping/unescaping[1].
