Mathematica Import/Export Format


Sequence of 8-bit characters.
Raw binary format.
  • Import can read any file as a sequence of characters.
  • Export writes a list of characters to a file.
  • Import["file", "Character8"] imports any file, returning a list of 8-bit characters.
  • Export["file", list, "Character8"] exports a list of characters to a binary file.
  • Export["file", expr, "Character8"] converts an expression to a string of characters and exports it to a binary file in which each byte represents a character.
  • Import["file", {"Character8", elem}] or Import["file", elem ] imports the specified element.
  • Import["file", {"Character8", {elem1, elem2, ...}}] imports multiple elements.
  • See the reference pages for full general information on Import and Export.
"Elements" elements and options available in this file
"Rules"full rules for each element and option
"Options"rules for options, properties, and settings
  • Data representation element:
"Data"list of 8-bit characters
  • Import["file", {"Character8", n}] gives the n^(th) byte.
"HeaderBytes"0how many bytes to skip at the beginning of the file
