Convert H5 to another file type
To convert H5 Data files to another format, you need HDFView or other Data software.
Convert a file to H5
To convert other file formats to the "Hierarchical Data Container" file type, you need software like HDFView or a similar tool.
About H5 files
An .H5 file is a Hierarchical Data Format 5 file, engineered to store and organize enormous amounts of complex data. It acts like a virtual file system within a single file, capable of holding multiple datasets, multi-dimensional arrays, and metadata. These files are the gold standard in scientific research, aerospace, and finance. They are also heavily used by machine learning frameworks like Keras to save trained neural network models and weight configurations. To open and view the raw data, professionals typically use HDFView, developed by The HDF Group, or programming libraries like h5py for Python.
Users often need to convert .H5 data because the format is highly specialized and binary. You cannot simply open an .H5 file in standard spreadsheet software like Microsoft Excel or read it in a basic text editor. This makes sharing simple subsets of data with non-technical stakeholders extremely frustrating. The data is locked behind specialized libraries, requiring programming knowledge to access.
The most common conversion targets for extracted data are CSV, JSON, or XML. However, converting an entire .H5 file directly to a single CSV is often impossible. .H5 stores hierarchical, multi-dimensional data structures, while CSV is strictly a flat, two-dimensional table. You will lose the internal directory structure and metadata during extraction and must pick a single 2D dataset to export.
Because .H5 is a complex, specialized data container, standard online converters frequently fail to process it. Only the original software or dedicated data science scripts can properly read or export the full hierarchical structure. If our analysis detects a supported underlying dataset, viewing or basic conversion 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.
FAQ
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 H5 Converter Story
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.
