A small, precise tool for a common problem: an API or a previous step in the flow returns a big JSON object, and you only need one value out of it.
What it can do
- Dot and bracket path expressions —
user.name,items[0].id, and anything you'd write with lodash'sget(), because that's exactly what powers it. - Accepts a JSON string, object, or array as input — no need to pre-parse it yourself.
returnNullOnErrortoggle — decide whether a missing path should fail the step or just return null.
Good to know
This is the tool that keeps a flow from passing an entire API response to the agent when it only needs one field — smaller context, more predictable behavior.
