JSON Import not working in Mathematica 10

Questions

The documentation for JSON import provides this example:

Import["ExampleData/temperatures.json"]

and shows a successful evaluation as output. However, evaluating this returns

.

If you import the file as Text, you can see it’s in proper JSON syntax.

Do any of you have this problem or is it specific to me? I’m on OSX Yosemite.

It works fine for me Jesse…

P.S. I am on OSX 10.9.4. Is your Mathematica the released version or is it still a pre-release?

It’s the release.

In[61]:= SystemInformation["Small"]

Out[61]= {"Kernel" -> {"SystemID" -> "MacOSX-x86-64", 
   "ReleaseID" -> "10.0.0.0 (5098698, 5098537)", 
   "CreationDate" -> 
    DateObject[{2014, 6, 29}, TimeObject[{20, 38, 32}]]}, 
 "FrontEnd" -> {"OperatingSystem" -> "MacOSX", 
   "ReleaseID" -> "10.0.0.0 (5098698, 2014062704)", 
   "CreationDate" -> 
    DateObject[{2014, 6, 27}, TimeObject[{23, 17, 40.}]]}}

Is it just for this file or do you get it for an arbitrary JSON file? Either way send in a bug report…

I originally got the error when attempting to import an external file, and confirmed it by trying with the example file.

7

Hmm. I do not have the time this morning to send in a bug report, but I too have been having problems importing JSON in Mathematica 10. I assumed it was user error or an error in the external file I was attempting to suck in, but now I am wondering if there is an issue. I would appreciate it if someone would take a look.

I checked and see that there is a current bug reported on this. I added a link to this discussion to that report.
