Private, ad-free JSON workspace
JSON Diff and Compare Tool
Compare two JSON inputs side by side to understand what changed between API responses, configuration files, test fixtures, or saved states. The compare workspace is designed for fast debugging without uploading data.
Why developers use it
- Compare two JSON documents in a side-by-side workspace.
- Spot additions, removals, and changed values while debugging.
- Import JSON files and keep comparison work separate from formatting panels.
- Move from diffing to formatting, editing, minifying, or converting as needed.
Common use cases
- Checking how an API response changed between releases.
- Comparing local and production configuration snapshots.
- Reviewing generated fixtures before updating tests.
Both JSON inputs are compared in your browser, so private responses and config values stay local.
FAQ
Can I compare two JSON files?
Yes. Import the JSON files into the compare workspace to review differences side by side.
Is JSON comparison private?
Yes. The comparison runs in the browser, so the JSON does not need to leave your device.
When should I use JSON compare instead of format?
Use the formatter to make one JSON document readable. Use compare when you need to see what changed between two JSON documents.
