Why it matters
JSON cleanup is rarely one-and-done. This workspace keeps the raw editor, search, and visual structure together so you can save progress, return later, and share the exact payload context.

Format, minify, clean, search, and copy JSON paths without leaving the browser.
Resume inspection work
Return to the same tree exploration, searches, and copied path context instead of starting over with every payload.
Share structured payloads
Send the workspace when a teammate needs the same JSON state, visual tree, and cleaned output in one browser-native flow.
Why it helps
Why use a visual JSON viewer
Understand nested API responses faster with raw and tree views side by side.
Copy JSON paths from nested structures for tests, code, or documentation.
Search large payloads without losing where a field lives in the object tree.
