JSON at a glance
JSON
Convert to JSON when data needs to move between systems, APIs, scripts, and applications in a structured but broadly compatible format.
It is ideal for payloads, configuration, manifests, exports, and machine-readable documents that need to be easy to parse programmatically.
Use it when interoperability and structured automation matter more than comments or document-style readability.
