Have no clue how to use
Even if i give 200% good json file this so called tool shouts "There was an error parsing the JSON document. The document may not be well-formed." or "Error: Parse error on line 1:"
Great extension, does what it promises. Would be useful to have an option to only process JSON sent with application/json headers though.
好东西
Works fine for small JSON responses. Causes the browser to hang for larger JSON - so I've had to default to keeping this off, and only turn the extension on when the tree view is helpful and the JSON is small.
where do paste the json and view it????
SPYWARE
Great extension. The FF extension is also good.
app so good
Works great! A little more info on the CSS styles could be helpful.
