Data Import and Export

Move data into and out of MATLAB®

Use the data import functions available in Statistics and Machine Learning Toolbox™ to import data into the MATLAB workspace from different file formats. Valid formats include tabular data, tab-delineated files, Microsoft® Excel® spreadsheets, and SAS® XPORT files. Alternatively, use the Import Tool to select and import data interactively.

Export data from the workspace, including case names, dataset arrays, and tabular data, and save it in a MATLAB-supported file format.
