Importing and Exporting
The Wolfram Language automatically handles hundreds of data formats and subformats—all coherently integrated through the Wolfram Language's uniform use of symbolic expressions. For each particular format, the correspondence between representations inside and outside the Wolfram Language can be specified at any level of detail using the Wolfram Language's general data elements mechanism.
Import — import from files and URLs
Export — export data, graphics, and expressions to files
ImportString, ExportString — import, export string data
ImportByteArray, ExportByteArray — import, export binary data
NotebookImport — import specified elements from a notebook
