Export
 Usage
• Export["file.ext", expr] exports data to a file, converting it to a format corresponding to the file extension ext.
• Export["file", expr, "format"] exports data to a file, converting it to the specified format.
Notes
• Export can handle numerical and textual data, graphics, sounds, material from notebooks, and general expressions in various formats. • The following basic formats are supported for numerical and textual data:
| "CSV" | comma-separated value tabular data (.csv) | | "Lines" | list of strings to be placed on separate lines | | "List" | list of numbers or strings to be placed on separate lines | | "Table" | list of lists of numbers or strings to be placed in a two-dimensional array (.dat) | | "Text" | single string of ordinary characters (.txt) | | "TSV" | tab-separated value tabular data (.tsv) | | "UnicodeText" | single string of 16-bit Unicode characters | | "Words" | list of strings to be separated by spaces |
• In "CSV", "List" and "Table" format, numbers are written in C or Fortran-like "E" notation when necessary. • In "CSV" format, columns are separated by commas, unless other settings are specified using ConversionOptions. • In "Table" format, columns are separated by spaces. • Export["file.txt", expr] uses "Text" format. • Export["file.dat", expr] uses "Table" format. • The following additional formats are also supported for numerical and textual data:
| "DIF" | Lotus Data Interchange Format (.dif) | | "FITS" | FITS astronomical data format (.fit, .fits) | | "HarwellBoeing" | Harwell-Boeing matrix format | | "HDF" | Hierarchical Data Format (.hdf) | | "HDF5" | HDF5 format (.h5) | | "MAT" | MAT matrix format (.mat) | | "MTX" | Matrix Market format (.mtx) | | "XLS" | Excel spreadsheet format (.xls) |
• All graphics formats in Export can handle any type of 2D or 3D Mathematica graphics. • In some formats, lists of frames for animated graphics can be given. • The following options can be given when exporting graphics: • The following graphics formats are independent of the setting for ImageResolution:
| "APS" | Mathematica abbreviated PostScript (.aps) | | "EPS" | Encapsulated PostScript (.eps) | | "PDF" | Adobe Acrobat portable document format (.pdf) | | "PICT" | Macintosh PICT | | "SVG" | Scalable Vector Graphics (.svg) | | "WMF" | Windows metafile format (.wmf) |
• The following graphics formats depend on the setting for ImageResolution:
| "AVI" | Audio Video Interleave format (.avi) | | "BMP" | Microsoft bitmap format (.bmp) | | "DICOM" | DICOM medical imaging format (.dcm, .dic) | | "EPSI" | Encapsulated PostScript with device-independent preview (.epsi) | | "EPSTIFF" | Encapsulated PostScript with TIFF preview | | "GIF" | GIF and animated GIF (.gif) | | "JPEG" | JPEG (.jpg, .jpeg) | | "MGF" | Mathematica system-independent raster graphics format (.mgf) | | "PBM" | portable bitmap format (.pbm) | | "PCX" | PCX format (.pcx) | | "PGM" | portable graymap format (.pgm) | | "PNG" | PNG format (.png) | | "PNM" | portable anymap format (.pnm) | | "PPM" | portable pixmap format (.ppm) | | "TIFF" | TIFF (.tif, .tiff) | | "XBitmap" | X window system bitmap (.xbm) |
• The following three-dimensional graphics formats are supported:
| "DXF" | AutoCAD drawing interchange format (.dxf) | | "STL" | STL stereolithography format (.stl) |
• The following sound formats are supported:
| "AIFF" | AIFF format (.aif, .aiff) | | "AU" |  law encoding (.au) | | "SND" | sound file format (.snd) | | "WAV" | Microsoft wave format (.wav) |
• Notebook and Cell objects, as well as any box expression obtained from ToBoxes, can be exported in the following formats:
| "HTML" | HTML (.htm, .html) | | "NB" | Mathematica notebook format (.nb) | | "TeX" | TeX (.tex) | | "XHTML+MathML" | XHTML with MathML inclusions (.xml) |
• These formats generate markup material which maintains much of the document structure that exists within Mathematica. • The following XML formats are supported:
| "ExpressionML" | format for Mathematica expressions | | "MathML" | format for mathematical expressions (.mml) | | "NotebookML" | format for notebook expressions (.nbml) | | "SVG" | Scalable Vector Graphics format for graphics (.svg) | | "XML" | format determined by content (.xml) |
• With format "MathML", box expressions are exported in terms of MathML presentation elements. Other expressions are if possible exported in TraditionalForm format. • With format "XML", notebook or cell expressions, and notebook objects, are exported as NotebookML. SymbolicXML expressions are exported as general XML. Other expressions are exported as ExpressionML. • Arbitrary Mathematica expressions can be exported in the following formats:
| "Dump" | internal binary format (.mx) | | "Expression" | InputForm textual format (.m) | | "ExpressionML" | XML-based ExpressionML format |
• Lists of numbers can be exported in the following raw binary formats:
| "Bit" | single bits (0 or 1) | | "Byte" | 8-bit unsigned integers | | "Complex64" | IEEE single-precision complex numbers | | "Complex128" | IEEE double-precision complex numbers | | "Complex256" | IEEE quad-precision complex numbers | | "Integer8" | 8-bit signed integers | | "Integer16" | 16-bit signed integers | | "Integer32" | 32-bit signed integers | | "Integer64" | 64-bit signed integers | | "Integer128" | 128-bit signed integers | | "Real32" | IEEE single-precision real numbers | | "Real64" | IEEE double-precision real numbers | | "Real128" | IEEE quad-precision real numbers | | "UnsignedInteger8" | 8-bit unsigned integers | | "UnsignedInteger16" | 16-bit unsigned integers | | "UnsignedInteger32" | 32-bit unsigned integers | | "UnsignedInteger64" | 64-bit unsigned integers | | "UnsignedInteger128" | 128-bit unsigned integers |
• In each case, numbers are if possible coerced to the format specified, with high-order bits dropped when necessary. • Byte ordering is specified by the ByteOrdering option. • Raw data for real and complex numbers may differ from one type of computer to another. • Lists of characters or strings can be exported in the following raw binary formats:
| "Character8" | 8-bit characters | | "Character16" | 16-bit characters | | "TerminatedString" | null-terminated strings of 8-bit characters |
• The following general options can be given: • Many details can be specified in the setting for ConversionOptions. • Possible formats accepted by Export are given in the list $ExportFormats. • Export["!prog", expr, "format"] exports data to a pipe. • New in Version 4; modified in 5.1.
