Extract all keys, paths, and values from a JSON object. JSON Key Extractor is a free online tool from the ToolsRift JSON Tools collection. It runs entirely in your browser — nothing to install, no signup, and your data never leaves your device.
Paste your JSON and the tool lists all keys with their dot-notation paths and values, so you can map the structure quickly.
Every key in the document along with its full path and the value stored there, including nested objects and arrays.
To understand the shape of large or unfamiliar JSON, build schemas, or find where a particular field lives.
Keys that repeat under different paths are each listed with their own unique path so nothing is hidden.
