HDF5 Viewer

Open a local .h5 or .hdf5 file to understand its hierarchy and storage metadata. File contents and object names never enter analytics.

General HDF5 files up to 1 GB. External links, virtual sources, filter plugins, remote URLs and filesystem paths are disabled.

General HDF5, not assumed NetCDF

Groups, arbitrary datasets, links, attributes and HDF5 datatypes are interpreted directly with h5py.

Deterministic type mappings

Compound, array, complex, binary, opaque and reference values use explicit JSON strings. Fill matches are marked in a separate field.

No silent truncation

Extraction streams every selected cell. If a filter is unavailable or the complete output cannot fit, the request fails clearly.
