Example

Let's say you have received raw data in JSON format and wish to extract the fields and format them as a CSV.

1

Raw data

[
  {
    "username": "user_1",
    "method": "POST",
    "endpoint": "breach log",
    "ip": "10.XXX.XX.XX",
    "description": "[Role] User performed an action on breach log",
    "viewport": [1920, 955],
    "usage": true
  },
  {
    "username": "user_1",
    "method": "POST",
    "endpoint": "event log",
    "ip": "10.XXX.XX.XX",
    "description": "[Role] User performed an action on event log from breach log",
    "viewport": [1920, 955],
    "usage": true
  },
  {
    "username": "service_user",
    "method": "POST",
    "endpoint": "/admin/age",
    "ip": "127.0.0.1",
    "status": 400
  },
  {
    "username": "user_2",
    "method": "POST",
    "endpoint": "/sso/login",
    "ip": "10.XXX.XX.XX",
    "status": 302
  }
]

2

Parse the JSON

Add a Parser to the canvas and extract the fields using the automatic parsing.

You have extracted the endpoint, ip, method, status and username into separate fields.

3

Build the message

Now use the Message Builder to create a CSV containing these fields as one message.

Drag the following fields to the Message area:

• method

• description

• object

• endpoint

• ip

• status

• username

• port

Fields delimiter: ,

if delimiter matches: Put "" in quotes.
