pspp-convert - convert SPSS files to other formats
pspp-convert [options] input output
pspp-convert --help | -h
pspp-convert --version | -v
The pspp-convert program reads input, which may be
an SPSS system file, an SPSS/PC+ system file, an SPSS portable file, or an
encrypted SPSS syntax file, and writes it to output, performing
format conversion as necessary.
The format of input is automatically detected, when
possible. The character encoding of old SPSS system files cannot always be
guessed correctly, and SPSS/PC+ system files do not include any indication
of their encoding. Use -e encoding to specify the encoding in
this case.
By default, the intended format for output is inferred from
its extension:
- csv
-
- txt
- Comma-separated value. Each value is formatted according to its variable's
print format. The first line in the file contains variable names.
- sav
-
- sys
- SPSS system file.
- por
- SPSS portable file.
- sps
- SPSS syntax file. (Only encrypted syntax files may be converted to this
format.)
Use -O extension to override the inferred format or
to specify the format for unrecognized extensions.
pspp-convert can convert most input formats to most output
formats. Encrypted system file and syntax files are exceptions: if the input
file is in an encrypted format, then the output file must be the same format
(decrypted).
- -O format
-
- --output-format=format
- Specifies the desired output format. format must be one of the
extensions listed above, e.g. -O csv requests comma-separated value
output.
- -c maxcases
-
- --cases=maxcases
- By default, all cases are copied from input to output.
Specifying this option to limit the number of cases written to
output to maxcases.
- -e charset
-
- --encoding=charset
- Overrides the encoding in which character strings in input are
interpreted. This option is necessary because old SPSS system files do not
self-identify their encoding.
- -p password
-
- --password=password
- Specifies the password to use to decrypt encrypted SPSS system file or
syntax file input. If this option is not specified,
pspp-convert prompts for the password.
- On multiuser systems, this option may not be safe because other users may
be able to see the password in process listings.
- -h
-
- --help
- Prints a usage message on stdout and exits.
- -v
-
- --version
- Prints version information on stdout and exits.
