What is normalized JSON diff?

Normalized JSON diff parses both documents and rewrites them into a consistent formatted form before comparison. This reduces noise from spacing and ordering differences so the diff focuses more on actual data changes.

When should I use raw text diff instead of normalized diff?

Use raw text diff when formatting itself matters or when you want to see every literal edit exactly as pasted. Use normalized diff when you care more about the underlying JSON structure than about whitespace and ordering changes.

What diff modes are available?

This JSON diff supports line diff, word diff, character diff, and unified patch output. Line diff is usually the best default for reviewing payload and config changes, while unified patch is useful when you want patch-style output.

Can I compare JSON files with reordered keys?

Yes. Normalized diff with optional key sorting is useful for that case because it reduces noise from reordered fields and lets you focus on actual additions, removals, and value changes.

Is the JSON diff tool private?

Yes. The comparison runs entirely in your browser, so your JSON content and generated diff output are not uploaded to a server.
