What is the simplest way to parse a json string in linux console?

I need a simple way to parse a json string received as a parameter.

Is there a console tool for doing that?

I’ll like to have something like this:

data=parsestring('{"field1": "value1", "field2": "value2"}')
echo data.field1
echo data.field2

>Solution :

Use jq if possible:

$ echo '{"field1": "value1", "field2": "value2"}' | jq
{
  "field1": "value1",
  "field2": "value2"
}

$ echo '{"field1": "value1", "field2": "value2"}' | jq '.field1'
"value1"
