Frequently Asked Questions

Find Quick Answers

What is JSONPath?

JSONPath is a query language for JSON, similar to XPath for XML. It allows you to select and extract data from JSON documents using path expressions.

What JSONPath syntax does this tool support?

The tool supports standard JSONPath syntax including: dot notation ($.store.book[0].title), bracket notation ($['store']['book'][0]['title']), wildcards ($.store.book[*].author), array slices ($.store.book[0:2]), and filters ($.store.book[?(@.price < 10)]).

Is my JSON data sent to a server?

No, all processing happens entirely in your browser using JavaScript. Your JSON data never leaves your computer.

Can I evaluate multiple JSONPath expressions at once?

Currently, you can evaluate one expression at a time. For multiple expressions, evaluate them separately one after another.
