JSON (.json)

MIME type: .
Data interchange format.
Commonly used in web service implementations.
Contains collections of unordered name-value pairs or ordered values.
JSON is an acronym derived from JavaScript Object Notation.

Import and Export support the JSON file format.

Import gives a rule-based representation of a JSON file.

Export exports a list of rules to JSON.

Import imports the specified element from a JSON file.

Import imports a subelement.

Import imports multiple elements.

The import format can be specified with Import or Import .

Export creates a JSON file by treating expr as specifying element elem.

Export exports expr with the specified option elements taken to have the specified values.

Export uses rules to specify the elements to be exported.

See the main function pages for full general information on Import and Export .

ImportString and ExportString support the JSON data format.

General Import elements:

"Elements" list of elements and options available in this file

"Rules" full list of rules for each element and option

"Options" list of rules for options, properties, and settings

Data representation element:

"Data" contents of a JSON file as nested rules

Import by default uses the element.

When importing from JSON, lists are returned in standard Mathematica sorting order.

Export option:

"Compact" False whether to use line breaks to format file content
