JSON Path Workflow Action

Problem Description

When processing JSON data, you are often faced with the challenge of accessing and manipulating specific parts of the data. Conventional methods such as traversing JSON objects or parsing strings can be time-consuming and error-prone, especially with complex data structures.

This is where the problem begins: How to efficiently and accurately access data in JSON structures without having to perform laborious iterations or manual string manipulations? The solution lies in the use of JSON Path Expressions, a syntax that has been specially developed for navigating and querying JSON data.

JSON Path in der DataEngine

The JSON Path Workflow Action is specially designed to simplify the handling of JSON structures in the DataEngine. With this workflow action, individual fields or sub-structures of a complex JSON structure can be read as soon as something changes in the underlying data record.

The following input fields are available in the interface:

  • JSON Source Field: Select the input field to which the JSON path expressions are applied.
  • Add Expression: Any number of expressions can be added with this button.

Each added expression consists of the target field, the expression and the default value:

  • Target: The result of the expression is written to this selected field
  • Expression: The actual JSON path expression that is applied to the JSON source field
  • Default: If the expression is incorrect or not applicable, this value is written to the target field

JSON Path Tools

If you want to test how JSON Path Expressions behave, you can test this with any Online Tool.
