About Us

JSONPathHub is a free online JSONPath tester and parser. It exists because modern APIs return deeply nested structures — orders inside customers inside payloads — and finding the one field you need should not mean expanding twenty tree nodes by hand.

What the Tool Does

Paste a JSON document, type a path such as $.store.book[*].author, and get every matching value back as a clean array. Three design decisions shape the experience:

• Syntax first. JSON is validated before anything runs. A stray bracket is reported with its exact line and column, so broken payloads never waste your time.
• The engine is real. A hand-written recursive-descent evaluator supports child access, recursive descent, wildcards, unions, slices and filter expressions — not a regex approximation.
• Suggestions from your data. Autocomplete lists the keys that actually exist at your cursor position, read live from the JSON you pasted.

Our Approach

A query tool sees your most sensitive payloads — production API responses, customer records, internal logs. That is why everything runs locally:

• No uploads. Parsing and evaluation happen in your browser with client-side JavaScript.
• No sign-up. No accounts, no email walls, no rate limits.
• No stored history. Close the tab and your data is gone.

The Name

"PathHub" captures the idea of a central desk for path work — and the site is styled like a surveyor's map, because that is the mental model: your JSON is terrain, and a JSONPath is the survey route that pinpoints every station worth visiting. Grid paper, coordinates and signal-orange route lines are there to make that idea tangible.
