How the JSON Size & Depth Stats Works

Analyzes JSON payloads to report minified and formatted byte size, maximum nesting depth, total key count, and a breakdown of value types.

Usage Example

Inspect API response weights and verify serialization performance budgets.

Frequently Asked Questions

Does this report gzip-compressed size?

No — it reports raw minified and formatted byte size (from TextEncoder), not gzip-compressed transfer size.
