In business automation
JSON is used to transfer data in a structure that can be mapped and checked. It is important to distinguish text, numbers, lists, and missing values because different systems may interpret them differently.
Examples
These examples illustrate a possible workflow. Adapt the connections and rules to your own systems.
Business process example
A form sends a customer object with a name, email, and product list. The process verifies that the product list is an array, separates the items, and calculates the order total before creating the record.
Relevant tools
- n8n
- Data passed between nodes can be mapped and processed as structures, including objects and arrays.
What to check
- A phone number is usually text, not a number for calculations. An incorrect conversion can remove a leading zero or country code.
