The .npz format is the standard for persisting NumPy arrays on disk. A .npz file contains multiple .npy files, one for each array. NPY files are binary, space-efficient and fast for numerical data compared to CSV files. CSV files store tabular data as human-readable plain text. NPYViewer visualizes .npy files without coding. It shows 2D arrays as images and 3D arrays as point clouds. Use np.save() to export a NumPy array to .npy file. np.load() loads .npy file into an array. NPY files store information to reconstruct the array like dtype and shape. NumPy provides large array and matrix support.
