Mathematica Import/Export Format

XPORT (.stx, .xpt)

MIME type: application/x-sas-xport
SAS XPORT transport format.
Legacy data exchange format.
Stores numerical datasets in a portable format.
Text format.
Developed in the late 1980s by SAS Institute.
  • Import fully supports the XPORT format.
  • Import["file.stx"] imports an XPORT file, returning all datasets arranged as a table.
  • Import["file.stx"] returns a table, representing each dataset as a column.
  • XPORT data is represented in Mathematica by real or integer numbers, strings, Boolean values True and False, and DateList specifications.
  • Import["file.stx", elem] imports the specified element from an XPORT file.
  • Import["file.stx", {elem, suba, subb, ...}] imports a subelement.
  • Import["file.stx", {{elem1, elem2, ...}}] imports multiple elements.
  • The import format can be specified with Import["file", "XPORT"] or Import["file", {"XPORT", elem, ...}].
  • See the reference pages for full general information on Import.
"Elements"list of elements and options available in this file
"Rules"full list of rules for each element and option
"Options"list of rules for options, properties and settings
  • Data representation elements:
"Data"datasets arranged as a table
"LabeledData"datasets given as a list of rules
  • Import uses the "Data" element by default.
  • Import["file.stx"]reads all datasets and returns them as a table.
  • Import["file.stx", "LabeledData"]imports the entire file and returns an expression of the form {a1 -> col1, a2 -> col2, ...}, where the ai are the table headings.
  • Meta-information elements:
"Labels"dataset names given as a list of strings
"Metadata"information about each dataset, given as a list of strings
"EmptyField"""how empty cells are represented in Mathematica
