What is a JSON data extractor?
Point a path like users.*.email at a JSON document and get the value from every element of that array, one per line. Dot and bracket notation are interchangeable, * fans out across arrays and objects, and an empty path dumps every leaf value. Parsing is done by the page itself; no payload is posted anywhere, which matters for API responses full of customer data.
How to use the JSON Data Extractor
- 1 Paste the JSON document.
- 2 Write a path such as items[0].sku, or use * to fan out across an array.
- 3 Leave the path empty to list every leaf value.
- 4 Copy the extracted values.
What you can use it for
- Pulling one field out of every object in an array.
- Grabbing a nested value without writing code.
- Listing all values to inspect an unfamiliar payload.
- Extracting IDs or emails from an API response.
Frequently asked questions
How do paths address nested data?
Chain keys and indexes with dots or brackets: users.0.email and users[0].email read the same field, and users.*.email visits every element of the array.
What comes back when the path box is empty?
A walk of the whole document that prints every primitive value, strings, numbers, booleans and nulls, which is a quick way to survey unfamiliar JSON.
What if the JSON does not parse?
You get the parse error rather than partial output. Fix the syntax, or run the input through the JSON formatter on this site to locate the problem line.
