Retrieve value from JSON object Flow Action

[earlduque]

This flow action is a JSON property accessor. It takes in a JSON object (either already parsed or as a string) and lets you extract a value from it using a property path. The property path can be a simple dot walk like user.name or something more complex with array indexes like user[4].name.

How it works

• Inputs:

  • inputs.objectParsed: a user-provided JSON object (already parsed).
  • inputs.objectStringified: a user-provided JSON string.
  • inputs.objectProperty: the property path you want to extract (supports dot walk and index notation).

• Process:

  1. It checks whether you gave it a parsed object or a stringified object.

     • If parsed, it uses that directly.
     • If stringified, it parses it into a JSON object.

  2. It converts your property path ("user[4].name") into a clean list of keys (["user", "4", "name"]).

  3. It walks through the object step by step to find the value at that path.

• Outputs:

  • outputs.objectvaluestring: the value as a string (if the result is an object or array, it gets JSON.stringify’d).
  • outputs.objectvaluejson: the raw JSON value (could be string, number, object, array, etc.).

Example

If your JSON object looks like this:

{
  "user": {
    "name": "Alice",
    "friends": [
      { "name": "Bob" },
      { "name": "Charlie" }
    ]
  }
}

• With objectProperty = "user.name"

  • outputs.objectvaluestring = "Alice"
  • outputs.objectvaluejson = "Alice"

• With objectProperty = "user.friends[1].name"

  • outputs.objectvaluestring = "Charlie"
  • outputs.objectvaluejson = "Charlie"

• With objectProperty = "user.friends"

  • outputs.objectvaluestring = "[{\"name\":\"Bob\"},{\"name\":\"Charlie\"}]"
  • outputs.objectvaluejson = [ { "name": "Bob" }, { "name": "Charlie" } ]
