Format comparison
JSON vs XML
JSON is the default for modern web APIs; XML still dominates document standards, feeds, and enterprise schemas.
Decision table
| Feature | JSON | XML |
|---|---|---|
| Verbosity | Compact | Verbose |
| Best for | APIs & app data | Documents & schemas |
| Human editing | Easy for objects | Heavier trees |
| Schemas | Optional (JSON Schema) | XSD / namespaces mature |
| Web APIs | Default | Legacy / regulated |
| Mixed content docs | Weak | Strong |
Choose JSON when…
- REST API payloads
- Frontend/backend contracts
- Mobile clients watching size
Choose XML when…
- RSS/Atom and sitemaps
- SVG and Office XML
- XSD-validated B2B
Verdict
Prefer JSON for new public APIs. Keep XML when a standard already requires it (SVG, Office internals, RSS, industry XSD).
