ViTables is a component of the PyTables family. It is a GUI for browsing and editing files in both PyTables and HDF5 formats. It is developed using Python and PyQt5 (the Python bindings to Qt), so it can run on any platform that supports these components.
ViTables capabilities include easy navigation through the data hierarchy, displaying of real data and its associated metadata, a simple, yet powerful, browsing of multidimensional data and much more.
As a viewer, one of the greatest strengths of ViTables is its ability to display very large datasets. Tables with one thousand millions of rows (and beyond) are navigated stunningly fast and with very low memory requirements. So, if you ever need to browse huge tables, don't hesitate, ViTables is your choice.
If you need a customized browser for managing your HDF5 data, ViTables is an excellent starting point.
