Just added that for parquet files

Hi all! I've been working on ML/Robotics research for a while and often work with HDF5, Parquet, and Zarr files. Personally, I love the myHDF5 viewer, but there's no good equivalent for Parquet and Zarr, and switching between different sites also gets annoying. So, I built a tool that provides a unified solution.

It currently supports viewing several formats, including HDF5, Parquet, Zarr, Arrow, JSONL, NumPy, TFRecord, etc. I'm hoping to add more features/formats depending on what people find useful!

It's free to use with no sign-up required.

Everything is loaded and parsed locally in your browser (WebAssembly + JS), so your data always remains on your machine. It's also built to remain responsive on big files via efficient reading, caching, and prefetching. Traversing through data files actually feels faster than existing solutions like myHDF5 with simple caching/prefetching strategies. It also supports some common data types that existing viewers don't support (e.g. float16, complex numbers for HDF5).

I'd appreciate any feedback (feel free to comment or send a message through the website). Looking forward to supporting additional features/file formats that the community finds useful!
