JSON Path Extractor

The JSON Path Extractor pulls specific values out of a JSON document using a simple dot-path notation, the way XPath works for XML. Give it a document and a path and it returns the value at that location, which is perfect for grabbing one field out of a large API response without writing a script. It is useful when you are debugging a payload, checking a nested value, or extracting the piece of data you care about from a bigger structure. The tool runs locally in your browser, so the document you inspect never leaves your device. Reaching into a nested document to retrieve one value is a routine task, and doing it by eye in a large payload is both slow and error prone. A path expression describes the route from the root to the value: a property name steps into an object, a bracket index steps into an array, and the two compose so that a path can traverse objects and arrays in any order. The notation mirrors how the same field would be accessed in code, which means a path you verify in the tool transfers directly into the script or query you are writing downstream, with no translation step. The common situations are all variations on the same need: checking a nested field in an API response while debugging, extracting one value from a large document without loading it all into an editor, and confirming that data exists where the documentation says it should. For arrays the path also makes the position explicit, which removes the ambiguity that comes from finding a value and not knowing which element it belonged to. The document is inspected in the browser, so nothing leaves your device.
