PAW — Payload Analysis Wingman

A fast, offline-capable JSON/XML viewer, formatter, and diff tool. Paste or upload a document to explore it as a searchable tree, validate it with precise error locations, convert JSON ↔ XML, query with JSONPath / XPath, and diff two documents.

index.html is fully self-contained (no build step, no dependencies) — just host the file anywhere static.

Publish it as a GitHub Page

1. Create a new repository on GitHub (e.g. refract).
2. Upload index.html (and this README.md + .nojekyll) to the repo root.
   • Web UI: open the repo → Add file → Upload files → drag them in → Commit changes.
   • Or via git:

     git init
     git add index.html README.md .nojekyll
     git commit -m "PAW – Payload Analysis Wingman"
     git branch -M main
     git remote add origin https://github.com/<you>/refract.git
     git push -u origin main

3. In the repo: Settings → Pages.
4. Under Build and deployment → Source, choose Deploy from a branch.
5. Set Branch to main and folder to / (root), then Save.
6. Wait ~1 minute, then visit: https://<you>.github.io/<repo>/

That's it — the whole app lives in that one file.

Notes

• The tool saves your document, theme, and layout to the browser's local storage and restores them on reload. "Share link" (or ⌘/Ctrl+S) encodes the current state into a URL you can bookmark or send.
• Fonts load from Google Fonts (needs a connection). Everything else runs locally in the browser — no data ever leaves the page.
• To update the page later, replace index.html with a newer build and commit.
