JSON Flatten API
Flatten and unflatten JSON. Turn a deeply nested JSON object into a single-level map of dot-notation keys (a.b.c → value, arrays become a.0, a.1), and turn a flat dot-notation map back into the original nested structure. Choose the delimiter (dot, slash, anything), limit the depth, or keep arrays intact. Perfect for environment variables, i18n/translation keys, preparing JSON for CSV or spreadsheet export, analytics event properties, config diffing and form serialisation. Pure local processing — no key, no third-party service, instant. Live. 3 endpoints. Distinct from JSON validation/formatting, JSONPath querying and type inference.
