• Inspect local MosaicML Streaming (MDS) shards (index.json + .mds/.mds.zst).
• Inspect local WebDataset shards (.tar, .tar.gz, .tar.zst).
• Inspect Hugging Face datasets via streaming API (no full local download).
• Inspect Zenodo datasets via HTTP Range request (no full local download).
• Preview json/audio/image, copy values, and open extracted fields with your default app.
