Frequently Asked Questions (JSON Diff)

What is a JSON Diff tool?

A JSON Diff tool compares two JSON documents (Original and Modified) side-by-side and highlights any changes (insertions in green, deletions in red, and updates) at the character level.

Can I edit the code directly inside the diff view?

Yes, you can edit the text directly in both panels of the Monaco Diff Editor. The diff updates in real-time as you type, copy, or paste.

Is this JSON comparison safe?

Yes. Like all other utilities in Developer Workbench, all comparison operations are performed entirely in your browser. No data is sent to a server.
