⚠ Constraints: Pure computation — no network calls, no API keys. Runs in any JavaScript/Python environment. JSONPath implementation covers common expressions but not the full JSONPath spec.

Inputs

Name	Type	Default	Description
strictMode	boolean	false	When true, missing source paths throw errors. When false, missing paths produce undefined.

strictModeboolean

When true, missing source paths throw errors. When false, missing paths produce undefined.

default: false

Outputs
