The two documents are identical.
| Path | Change | Value |
|---|---|---|
How it works
Both inputs are parsed to objects and walked recursively; mismatching keys and values are collected with their dotted paths and a change type — all locally.
100% client-side — nothing you paste is ever uploaded.
Frequently asked questions
How does the comparison work?
Both documents are parsed and compared key by key, recursively. You get the dotted path to each difference and whether it was added, removed or changed.
Is my data uploaded?
No — both documents are parsed and diffed entirely in your browser.
