如何查看 H5、HDF5、HDF、NXS、NETCDF4 文件
HDF5 is widely used for research, instrument output, and machine-learning data. The viewer reads hierarchy and bounded slices instead of loading entire arrays.
- Choose an HDF5, H5, HDF, NeXus, or HDF5-based NetCDF4 file.
- Expand the group tree and select a dataset.
- Inspect shape, dtype, compression, chunks, and attributes.
- Set a bounded slice for a table, line, or 2D heatmap preview.
Wobei es hilft
- No HDFView or Python script required
- Quick dataset-path discovery
- The file is parsed inside this browser tab and is not uploaded to FreeTool to use the tool.
Kompatibilität und Einschränkungen
- Classic NetCDF3 is unsupported even when the extension is .nc
- Object references, custom filters, and some compound types may not preview
- Large arrays are sliced; whole-database export is unavailable
Häufig gestellte Fragen
Why will my .nc file not open?
Only HDF5-based NetCDF4 is supported; classic NetCDF needs a different parser.
Can I export CSV?
Only a small current 2D slice; use Python, R, or MATLAB for large or multidimensional datasets.
Is research data uploaded?
The file is parsed inside this browser tab and is not uploaded to FreeTool to use the tool.
