How to use
- Paste valid JSON into the Original and Updated panels, each up to 100,000 characters.
- Select Compare JSON to parse both values and compare objects, arrays, and primitive values safely.
- Review the added, removed, and changed counts, then copy the report if needed.
Safe local parsing
The checker uses JSON.parse and never evaluates pasted text as code. Each panel is limited to 100,000 characters, and parsing, comparison, copying, and clearing happen in your browser.
Stable paths and sorting
Object keys are compared in sorted order and shown with safe JSONPath-like paths such as $.profile.name or $.items[0]. Added, removed, and changed entries are counted separately.
Frequently asked questions
You may also want to know
Does key order affect the result?
No. Object keys are compared by name and displayed in stable alphabetical order.
How are arrays compared?
Array positions are compared in order, so an insertion can produce changed, added, or removed index paths.
Is my JSON uploaded?
No. Both values stay in your browser and are never sent to a server.
