JsonComparator is a small utility class that compares two JSON objects (as strings) and returns structured differences. Ideal for building human-friendly or machine-readable logs when objects change.

Common uses:

• Support / Audit logs
  Record what fields changed and their before/after values.

• Change notifications
  Include the HTML render ready description in email or UI notifications to show what changed.

• Webhook payload comparison
  Verify delta between old and new payloads for idempotency checks.

• Regression / integration tests
  Detect unexpected changes in API responses or config objects.

Simple step-by-step how to use and configure.
1. Add JsonComparator public elements to your app

2. Feed it two JSON strings (PrevJson = Original value of the JSON, NewJson = Changed value of the JSON)
GetJsonDifferences sample usage

GetJsonDifferences result in a list widget

GetOperationDetails sample usage

GetOperationDetails result rendered using HTMLinject

What to expect

• If a field is added: OriginalValue = "", NewValue = "value".

• If a field is removed: OriginalValue = "value", NewValue = "".

• If a field changed: OriginalValue = "old", NewValue = "new".

• Property name matching is case-insensitive (Name == name).

• Arrays are compared element-by-element (order matters).

• Nested objects/arrays: OriginalValue / NewValue will contain the raw JSON text for that value.
