# JSON Related-Nodes (2)

When working with JSON payloads, two websites are particularly helpful for evaluating data and retrieving specific values:

## JSON Formatter & Validator

[JSON Formatter & Validator](https://jsonformatter.curiousconcept.com) is useful for checking JSON payloads, which are often placed in the body field of various nodes.

## JSON Path Finder

[JSON Path Finder](https://jsonpathfinder.com) helps generate extraction paths for use in the [JSON Extract Action](/helmut4-releases/v4.9.0/helmut4-components/streamdesigner/nodes/actions/misc/json-related-nodes-2/json-extract-action.md), enabling you to pull values from predefined keys.

For example, to extract the `version` key from within the body segment, you would use the extraction path: `body.version`.<br>
