== Example ==
This is an example of JSON:
<syntaxhighlight lang="javascript">
{
"firstName": "John",
"lastName" : "Smith",
"age" : 25,
"address" :
{
"streetAddress": "21 2nd Street",
"city" : "New York",
"state" : "NY",
"postalCode" : "10021"
},
"phoneNumber":
[
{
"type" : "",
"number": "212 555-1234"
},
{
"type" : "fax",
"number": "646 555-4567"
}
]
}
</syntaxhighlight>
'''JSON Encoding and Decoding in Python'''
Encoding:
<syntaxhighlight lang="python">
import json
sampleDict = {
"firstName": "John",
"lastName" : "Smith"
}
sampleJson = json.dumps(sampleDict, indent=4)
</syntaxhighlight>
Decoding:
<syntaxhighlight lang="python">
import json
# A JSON string or can be a JSON response
sampleJson = """{ "firstName": "John", "lastName" : "Smith"}"""
sampleDict = json.loads(sampleJson)
print(sampleDict['firstName'])
print(sampleDict['lastName'])
</syntaxhighlight>

JSON is formed in key-value pairs in the format <code>"key": "value"</code>. Each pair is separated with commas. Note that a JSON file must start with an opening brace (<code>{</code>) and end with a closing brace (<code>}</code>).<ref name="rfc4627"></ref>

This is an example of JSON:
<syntaxhighlight lang="javascript">
{
"firstName": "John",
"lastName" : "Smith",
