Parse JSON

Parses a JSON string into a native object or array, making its fields accessible via expressions in downstream nodes.

Properties

Property	Required	Description
JSON Input	Yes	The JSON string to parse. Supports expressions

Output

Field	Type	Description
data	Object | Array	The parsed JSON value. An object when the root is {}, an array when the root is []

Access the output in downstream nodes:

{{ $nodes['Parse JSON'].data }}
{{ $nodes['Parse JSON'].data.user.email }}
{{ $nodes['Parse JSON'].data[0].id }}

Replace Parse JSON with the actual name you gave the node.

Behaviour

• An empty or whitespace-only input produces data: null without failing.
• If the string is not valid JSON the node fails with a parse error.
• All standard JSON value types are preserved: objects, arrays, strings, numbers, booleans, and null.

Example

Parse a JSON response from an HTTP request and read a field:

1. Add an HTTP Request node to call your API.
2. Add a Parse JSON node. Set JSON Input to {{ $nodes['HTTP Request'].responseBody }}.
3. In a downstream node, access fields with {{ $nodes['Parse JSON'].data.fieldName }}.

To loop over a JSON array response:

1. After Parse JSON, connect a Loop node.
2. Set Items to {{ $nodes['Parse JSON'].data }}.
3. Inside the loop body, reference each item with {{ $nodes['$loop'].currentItem }}.

Notes

• If you already have a JavaScript object (not a string), you do not need this node — use the value directly in expressions.
• For XML responses use Parse XML. For CSV responses use Parse CSV.
