READSTAT(1)		     General Commands Manual		     READSTAT(1)

NAME
     readstat - read and write data set files from SAS, SPSS, and Stata

SYNOPSIS
     readstat input-file

     readstat [-f] input-file output-file

     readstat [-f] input-file metadata-file output-file

DESCRIPTION
     readstat converts data set files from popular statistics packages stored in
     both plain-text and binary formats.

     In  the first invocation style, readstat displays metadata from input-file,
     including the row count, column count, text encoding, and	timestamp.   in-
     put-file should be a file with one of the following extensions:

     sas7bdat
	    SAS binary file, created with SAS version 7 or newer

     xpt    SAS  portable  file,  version  5  or version 8, created with the SAS
	    XPORT command

     sav    SPSS uncompressed binary file

     zsav   SPSS compressed binary file

     por    SPSS portable file

     dta    Stata binary file, version 104 or newer

     If the row count cannot be determined from the file header, which is  some-
     times  the  case  with  SPSS  binary  files  and  always the case with SPSS
     portable files, readstat will report a value of -1.

     In the second invocation style, readstat  converts  input-file  to  output-
     file,  e.g. a SAS portable file to a Stata binary file.  In addition to the
     preceding extension list, output-file may have extension csv or xlsx, which
     creates a CSV or Excel file, respectively.

     The third invocation style is used when additional metadata about the input
     file, such as value labels or column widths, is stored in a separate  file.
     Several types of metadata file are supported:

     sas7bcat
	    SAS binary "catalog" file, created with SAS version 7 or newer, con-
	    taining value labels

     json   JavaScript	Object	Notation (JSON) file, containing column metadata
	    that cannot be gleaned from the input CSV. For details, see the man-
	    ual page for the extract_metadata command.

     dct    Stata dictionary file, containing the data layout and  column  meta-
	    data for a plain-text input file.

     sps    SPSS  command  file,  describing the data layout and column metadata
	    for a plain-text input file.

     sps    SAS command file, describing the data layout and column metadata for
	    a plain-text input file.

     The last three formats can be used for both fixed-width and delimiter-sepa-
     rated (e.g. tab-separated) input  files.  These  are  commonly  distributed
     along with plain-text ASCII data sets.

     Both input and output formats are implied by the file extension.

OPTIONS
     -f     Overwrite any existing output-file.

BUGS
     SAS  binary  files created by readstat do not open with current versions of
     SAS.

     The finer details of format strings (e.g. "%8.2g") are  not  properly  con-
     verted between file formats.
