Optimizely Package Explorer: Now With Extra Superpowers

If you’ve ever opened a .episerverdata file and asked “What is in here?” (guilty as charged) — then this is your moment. We’ve given our open-source tool CodeArt.Optimizely.PackageExplorer a fresh update with new features and polish, so you can slice, dice and explore those content packages with ease. Grab some coffee (or your beverage of choice) and let’s dive in.

What’s new in this update

(Yes, I know I sound like a tech-mag announcement — but bear with me.)

Here’s what’s been improved / added in this release of PackageExplorer:

Sharper UI & UX polish – The Blazor-WebAssembly front-end (built with MudBlazor) now feels smoother and more intuitive: upload your package, and instantly navigate content types, media, visitor groups in a structured way.
Deeper content inspection – You can now more easily drill down into content items, their metadata, and see the tree structure of items and their relationships. No more “mystery ZIP” syndrome.
Better support for .episerverdata format – The tool remains focused on those export/import packages used in Optimizely / Episerver workflows.
Browser-only, zero backend required – Your data stays local. We run entirely in your browser (Blazor WebAssembly) so upload, inspect — without worrying about data leaving your machine.
Updated roadmap & open to contributions – This isn’t just “bug-fix mode”: we’ve laid out a path for future enhancements (editing support, diffing packages, export formats etc). So if you’ve ever thought “hey, I wish it could…” — now’s your chance.

Why this update matters

You’re reading this because you’re working with Optimizely CMS (or soon will). And if you’ve done any content migrations, site upgrades, package inspections, you know the pain: packages full of old media, content types you forgot about, or “what the heck is that visitor group doing here?” moments.

With this update, PackageExplorer becomes your magnifying glass over those content packages. Instead of:

Trying to unzip and parse raw XML or ZIP contents
Guessing what types and items are inside
Migrating things by “hope and pray”

You get:

A clear tree view of content, media, visitor groups
The ability to quickly see what’s in the package (and what’s not)
A tool that helps you audit, inspect, and prepare confidently for migrations or content imports

And yes — as your friendly AI collaborator I’ll say: saving you dev time is always a win.

Get started (it’s easy)

Hop over to the GitHub repo: github.com/CodeArtDK/CodeArt.Optimizely.PackageExplorer GitHub
Try the live demo: upload one of your .episerverdata file and explore. GitHub
Want to run locally? Clone and dotnet run the Blazor project (see README).
Found a bug, have a feature request, or want to contribute? Great! Open an issue / PR. Issues

What’s coming soon (spoiler alert)

Because we’re not stopping here — here are glimpses of what’s on the horizon:

✏️ Edit package contents – Imagine tweaking things inside the package, saving/exporting changed packages.
🧮 Diff/compare two packages – Spot what changed between versions of a package (maybe between dev and live).
🔄 Export to other formats – JSON, CSV, Excel… or cross-CMS import formats.
🧰 CLI / automation support – Integrate into build pipelines or scripting workflows.
🌐 Media previews & improved visuals – See images inside the package, not just file names.

If any of those make you go “ooooh,” let me know — we can prioritise features together.

Try it right now

Seriously. Upload a package you already have lying around (you know you have one). See what’s in there. Uncover forgotten media, orphan content types, weird visitor groups. Show your colleagues “Look at this, I found that thing.”

Feel free to send feedback — whether a bug, a feature wishlist, or just “Hey – adding this would help me with my UI audit”.

Thanks for checking out the update. May your packages be transparent, your content tidy, and your migration paths smooth.
