JSON decoder in "Decoder"

Stefano | Last updated: Sep 13, 2015 04:06AM UTC

Hi PORTSWIGGER team, I would be really greatful if you add support for JSON decoding to "Decoder". Because usually I find URLs like https%3a\/\/www.google.com\/blablabla... and I have to use other decoder like unescape() to work with a valid URL. Thanks.

Thanks for this. We have this request captured in our backlog and we'll look at it when we next have a general push on the Decoder tool.

The JSON Beautifier extension in the BApp store does this. If you notice any problems or shortcomings with this, do let us know.

Can I add my pin to the map for this request, please. A JSON expander would be really helpful. Mind you a new approach to the decoder, which can operated on different tree branches differently would be really nice.

Hello! +1 JSON Decoder realy need, but in last version it not exists in BS. And in work with big json-data json beautyfiler may be very helpfull, like http://codebeautify.org/jsonviewer (view structured json objects with tabs and lines breaks)

Hi +1 too. Still missing in 1.7.23. Portswigger, why is it missing as XML is supported.

Any news about this feature? I read the last comment about JSON Beautifier but it doesn't serve my purpose.

Hi Stefano, Unfortunately, there hasn't been any work on this. Because JSON Beautifier works for most people, it has taken the urgency away. What do you need to do that JSON Beautifier can't help with?

Hi Paul, Okay, I understand. What I need is just something like what I can do with URL encoded values and Decoder. Let's say that I see something like this: <script> var something = '{"interesting endpoint": "\/long\/...\/path\/file.ext"}' var other_example_that_ive_seen = '\/other\/long\/path\/....\/file.ext' var other_one = '\x22asdasd\x3c\x22....loooong....\x5c' </script> Then I want to do something like select \/long\/...\/path\/file.ext and press something like cmd+Shift+U or copy & paste the selection in Decoder. Just as simple as that. Sometimes I've needed to encode some value too. Maybe programming wise it is difficult to implement in Java, but it would save me time and "hand effort". JSON Beautifier is not right for me because it expects a JSON document. As I mentioned, I just want to select something and decode/encode that like I can do now with URL encoded values. Thank you for the reply.

Hi Stefano, Thanks for the feedback. We'll bear this in mind when we revisit the decoder functionality.
