JSON Parser

This REST tool outputs a list of names and a list of values from a JSON object. If you have nested objects, the parser places the entire nested object in the values list as a string. To parse nested JSON objects fully, use multiple JSON Parser steps.

Important!

Names must be unique. If names aren't unique, JSON Parser does not throw an error, but the JSON is not correctly parsed. For example, {user: johndoe, user: janedoe} does not cause an error, but is not parsed correctly.
Starting with Interaction Designer 2017 R3, JSON Parser can parse a JSON object that includes these keywords: break, case, catch, class, const, continue, debugger, default, delete, do, else, enum, export, extends, finally, for, function, if, implements, import, in, instanceof, interface, let, new, package, private, protected, public, return, static, super, switch, this, throw, try, var, void, while, with, yield. Previously, a JSON object that contained a keyword would cause the JSON Parser to exit with the failure path.

JSON Parser example

Given the following JSON object, JSON Parser returns three list of string variables: one for the names, one for the values, and one for the data types of each item.

{
"user": "johndoe",
"admin": false,
"uid": 1000,
"groups": ["users", "wheel", "audio", 
 
 "video"], "innerJSON": {
"observer": "janedoe",
"readonly": true,
"uid": 1001,
"watchlists": ["Aveeno", "Purell", 
 "Blistex", "Carmex"]
}
}
