Overview (EXPORT command)
The EXPORT
command is deprecated and will not be supported in future releases.
The EXPORT
command is not supported in Unicode mode.
EXPORT
produces
a portable data file. A portable data file is a data file created
used to transport data between different types of computers and operating
systems, or other software using the same portable file format. A
portable file contains all of the data and dictionary information
stored in the active dataset from which it was created.
EXPORT
is similar
to the SAVE
command. It can occur
in the same position in the command sequence as the SAVE
command and saves the active dataset.
The file includes the results of all permanent transformations and
any temporary transformations made just prior to the EXPORT
command. The active dataset is unchanged
after the EXPORT
command.
- In most cases, saving data in portable format is no longer necessary, since IBM® SPSS® Statistics data files should be platform/operating system independent.
- To export data in external data formats (e.g., Excel, SAS, Stata, CSV, tab-delimited), use SAVE TRANSLATE.
Options
Format. You can control the format of
the portable file using the TYPE
subcommand.
Variables. You can save a subset of variables from the
active dataset and rename the variables using the DROP
, KEEP
, and RENAME
subcommands. You
can also produce a record of all variables and their names on the
exported file with the MAP
subcommand.
Precision. You can specify the number of decimal digits of precision for the
values of all numeric variables on the DIGITS
subcommand.
Basic Specification
The basic
specification is the OUTFILE
subcommand
with a file specification. All variables from the active dataset are
written to the portable file, with variable names, variable and value
labels, missing-value flags, and print and write formats.
Subcommand Order
Subcommands can be named in any order.
Operations
- Portable files are written with 80-character record lengths.
- Portable files may contain some unprintable characters.
- The active dataset is still available for transformations and procedures after the portable file is created.
- The system variables $CASENUM and $DATE are assigned when the file is read by
IMPORT
. - If the
WEIGHT
command is used beforeEXPORT
, the weighting variable is included in the portable file. - Variable names that exceed eight bytes are converted to unique eight-byte names—for example, mylongrootname1, mylongrootname2, and mylongrootname3 would be converted to mylongro, mylong_2, and mylong_3, respectively.
Limitations
The EXPORT
command is not
supported in Unicode mode. For more information, see SET command, UNICODE subcommand.
