Importing and Exporting

The Wolfram Language automatically handles hundreds of data formats and subformatsall 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.
