MATHEMATICA IMPORT/EXPORT FORMAT

NB (.nb)

Registered MIME types: application/mathematica, application/vnd.wolfram.mathematica
Mathematica notebooks.
Used for storing and exchanging Mathematica input and output and for the creation of interactive technical documents.
Native file format of the Mathematica notebook interface.
ASCII format based on the Mathematica expression syntax.
Stores text, typeset expressions, graphics, animations, sounds, and other Mathematica input and output.
Supports interactive elements like hyperlinks, buttons, sliders, and other graphical user interface features.
Uses external or embedded stylesheets for specifying the appearance onscreen and in print.
Developed since 1988 by Wolfram Research.

Import and Export fully support the Mathematica notebook format.

Import and Export Import and Export

Import["file.nb"] reads a Mathematica notebook and returns it as a Notebook expression.
Export["file.nb", expr] exports a Notebook, Cell, or box expression, as well as arbitrary mathematical expressions as a notebook.
Import["file.nb", elem] imports the specified element from a notebook.
Import["file.nb", {elem, sub_a, sub_b, ...}] imports a subelement.
Import["file.nb", {{elem₁, elem₂, ...}}] imports multiple elements.
The import format can be specified with Import["file", "NB"] or Import["file", {"NB", elem, ...}].
Export["file.nb", expr, elem] creates a notebook by treating expr as specifying element elem.
Export["file.nb", {expr₁, expr₂, ...}, {{elem₁, elem₂, ...}}] treats each as specifying the corresponding .
Export["file.nb", expr, opt₁->val₁, ...] exports expr with the specified option elements taken to have the specified values.
Export["file.nb", {elem₁->expr₁, elem₂->expr₂, ...}, "Rules"] uses rules to specify the elements to be exported.
Put[expr₁, expr₂, ..., "file.nb"] can be used to export multiple expressions.
See the reference pages for full general information on Import and Export.
ImportString and ExportString support the notebook format.
