Import and Export

This chapter reviews the import and export of data, including the relevant Wolfram Language commands and the import and export formats that Mathematica supports. Experimental data can come from different sources; the way to process this external data is to import it through Wolfram Language. Data that has been calculated or obtained externally can be transferred to Mathematica and exported for use on other platforms. However, Mathematica has tools to handle different data types (numbers, text, audio, graphics, and images). This chapter focuses on working with numerical and categorical data, the most frequently used data types for analysis.
