JSON Diff FAQ
What does the diff show?
It computes a structural delta between two JSON documents and lists exactly what was added, removed, or changed — powered by jsondiffpatch.
Is there a visual view?
Yes. The Visual diff panel highlights additions in green and deletions in red, side by side with the raw delta. Toggle "Show unchanged" to see full context.
Is my data uploaded?
No. Both documents stay in your browser; the comparison runs locally.
