Calculating…
Who uses it, and for what
Stop guessing paths in deeply nested webhook payloads from Stripe, Shopify or Typeform.
Learn how n8n addresses arrays and keys with spaces by seeing the expression for each field.
An expression returns undefined: compare it with the exact path generated here.
How this tool works
Walks the whole JSON tree
Every nested object and array item is visited, up to 400 fields.
Writes valid expressions
Keys with spaces or dashes use bracket notation; array items use [index].
Supports named nodes
Switch the root to $('Node name').item.json to reference a node further back in the workflow.
Frequently asked questions
Why does my expression return undefined?
Usually a wrong level (the data sits under body), an array that needs [0], or a key with a space that needs bracket notation. The generated path fixes all three.
What is the difference between $json and $('Node')?
$json reads the item from the node directly before. $('Node').item.json reads the matching item from any earlier node by name.
Is my data uploaded?
No. Parsing happens in your browser.
