About Structura
Structura compares two JSON documents and lists every added, removed and changed value with its exact path. You can compare arrays by position, as unordered collections or by an id property, skip keys such as timestamps, and download the result as a report or a JSON Patch.
How it works
Structura runs in your web browser. The JSON you paste or open is processed on your device, and there is no account system, upload endpoint or database for your entries. Your comparison options are remembered in this browser; your JSON is not saved.
Who makes it
Structura is part of Toolwoven, a small independent collection of free browser tools. Each tool focuses on one practical task and can be used without signing up.
