Extract text from Hierarchical data files (H5)
To convert H5 Data files to another format, you need HDFView or other Data software.
To convert other file formats to the "Hierarchical Data Format" file type, you need software like HDFView or a similar tool.
An .H5 file is a container saved in the Hierarchical Data Format version 5. It is designed to store massive, complex datasets. It operates like a miniature file system within a single file, organizing multidimensional arrays of data into "datasets" and "groups." This format is heavily utilized in scientific computing, aerospace engineering, and machine learning, particularly for saving neural network architectures and weights in frameworks like Keras.
To open an .H5 file locally, you typically need specialized software like HDFView developed by The HDF Group, or programming libraries such as h5py and pandas in Python. For more background on the standard, you can review its Wikipedia page.
Users frequently need to convert .H5 data to flat text formats like CSV or JSON to share data with colleagues or import it into standard spreadsheet applications like Microsoft Excel. The main disadvantage of the .H5 format is its rigid, binary nature; it cannot be inspected in a standard text editor and requires a heavy software stack to process.
The most practical conversion targets are CSV or JSON. However, because .H5 files are highly nested, exporting them to a flat CSV often results in a severe loss of hierarchical metadata and structural context. You usually have to extract one specific dataset at a time rather than converting the entire file at once.
Because .H5 is a complex, binary format, it is extremely difficult for generic online tools to parse. Often, only the original libraries can properly read the data structure. Just drag and drop your file to identify the format, view it, and convert it when possible on convert.guru. If our analysis detects a supported underlying or embedded format, viewing or extracting specific tables may still be possible.
Convert.Guru analyzes your H5 file, detects the exact format, and lets you read the text inside.
Users also converted HDF5, HDF, ZIP, H5AD, H5P, PKL, CGNS, H5Z, KERAS, HS, TXT, HD5 and HS5 files.
If you want to convert H5 file to CSV, JSON, PT, PTH, XML, YAML, YML, TOML, INI, CFG, CONF or DAT, you can use HDFView or similar software from the "Scientific Data Storage" category. In the File menu, look for Save As… or Export….
To convert DBF, XML, SQLITE, XLSX, SQL, TSV, ACCDB, YAML, MDB, CSV, ODS or JSON files to H5, try HDFView or another comparable tool in the "Scientific Data Storage" category.
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our H5 converter.
