JSON Path Extractor

Extract every path from a JSON document — dotted keys and array indexes — so you can see the shape of a payload or build selectors for transforms.

JSON Path Extractor — Frequently Asked Questions

A path list is often the fastest way to understand a payload you did not design. It shows which fields exist, how deep the nesting goes, and where arrays appear — enough to draft a TypeScript type or a JSON Schema without reading the whole document by eye.

As dotted keys with numeric array indexes, for example order.items.0.sku. That matches how most flatteners and many templating languages refer to nested values.

Flatten produces a new JSON object whose keys are those paths. The path extractor only lists the paths, which is what you want when you are inventorying a schema rather than transforming the data.

No. Every tool runs in your browser as JavaScript — your data is never uploaded, never logged, and never sent to a server. You can confirm it by watching the Network tab in devtools while you work, or by disconnecting from the internet after the page loads and seeing that everything still functions. That matters for JSON in particular, because API responses routinely contain personal data, tokens, and internal identifiers.

Beautify or minify a payload, sort keys so two files line up in a diff, flatten nesting for a translation file, repair the trailing comma that broke a parse, convert to YAML, or list every path the document contains.
