jsonlint's Issues

XML to JSON source or privacy

Good morning, I cannot find any repository or contact point for the XML to JSON tool, so I'm writing here, instead.
I'd like to use the XML to JSON tool but don't want my data to be sent to your server.

My question is, therefore: do you have a source I can install locally on my server?
Or, if I use your online tool, is my data sent to your servers?

Duplicate keys raise an error

Example:

{"name": "Alice", "age": 30, "age": 30}

JSONLint says:

Invalid JSON!
Error: Duplicate key 'age'

However, duplicate keys are valid. ECMA-404 says:

The JSON syntax does not impose any restrictions on the strings used as names, does not require that name strings be unique, ...

So this data is valid.

That said, I agree that duplicate keys aren't good. They should raise a warning instead.
