Begrensninger

Requires JavaScript. Extremely large inputs may slow the browser tab. Results depend on your browser APIs; there is no server-side processing quota because nothing is uploaded.

When to use

When you want a quick, free utility without creating an account or sending content to an online converter.

When not to use

When you need server-side integration, batch automation at scale, or certified compliance tooling.

Privacy note

Tool inputs are processed in your browser only. Theme, language and favorites may use localStorage; hosting may keep standard access logs (IP, UA, URL) without tool payloads.

FAQ（5）

Deep vs shallow?

The tool walks object trees and reports added/removed/changed paths.

Array order?

Arrays are compared by index; reordered items appear as changes.

Privacy?

Both JSON documents stay in the browser.

Pretty output?

Differences are listed as human-readable path ops you can copy.

Huge JSON?

Very large trees may slow the UI—compare focused subsets when possible.
