JSON Processor – Parse & Produce JSON​

Summary (SEO Meta Description):
The JSON Processor in WeHub parses text into JSON or produces JSON from objects.
Configure schema validation and truncation options to safely handle structured data.

Overview​

The JSON Processor supports two complementary actions:

  • Parse JSON → Convert raw text into a structured JSON object.
  • Produce JSON → Generate a JSON string from workflow objects.

Both actions support schema validation and truncation settings, ensuring clean and consistent JSON for downstream processing.

⚙️ Configuration Options​

  • Produce JSON → Serialize workflow context into a JSON string for HTTP calls.
  • Validation → Enforce schema compliance on data at workflow boundaries.
