JSON Helper is an agent which allows you to do useful things with JSON (JavaScript Object Notation) directly from AppleScript.

JSON Helper has no interface, and runs in the background waiting for AppleScripts to ask it to do something. JSON Helper is by far the easiest way to work with JSON in AppleScript.

JSON Helper lets you convert JSON directly into AppleScript records, lists and strings, and convert AppleScript records, lists and strings into JSON.

JSON Helper also makes it easy to parse the responses of many popular web services directly into AppleScript with convenience methods for fetching and parsing the responses from URLs.

See our web page for more information and a set of useful examples.

Works perfectly

Very happy with this app, makes it extremely simple to fetch data from JSON files and use within Applescript. The developer support was very helpful too when I asked a question via email.


Works as advertised.

This product is genius. It works as advertised. I’m very happy with it. Now I just with there was a “CSV Helper for Applescript”… :)

Fails on very basic things.

Take, for example:

global alertResult
tell application "Google Chrome"
set alertResult to display alert "Hi!" buttons {"Well, hello there."}
end tell
tell application "JSON Helper"
set jsonResult to make JSON from alertResult
end tell

This results in an error, because the display alert returns the following record:

{button returned:”Well, hello there."}

and JSON Helper barfs on it. It does work if the key is properly quoted in AppleScript:

{|button returned|:"Well, hello there.”}

but that’s not how display alert returns it.
