EXTRACT_METADATA(1) General Commands Manual EXTRACT_METADATA(1) NAME extract_metadata - read column metadata from SPSS and Stata binary files, and format it as JSON SYNOPSIS extract_metadata input-file output-file DESCRIPTION extract_metadata reads column metadata from existing binary data files, so that readstat can produce new, column-compatible binary files from CSV input files. Both programs use JSON as a metadata interchange for- mat. The input-file should be a file with one of the following extensions: dta Stata binary file, version 104 or newer sav SPSS uncompressed binary file zsav SPSS compressed binary file In all cases, output-file should end in .json. EXAMPLE Suppose you have a Stata file with last year's survey data, and want to produce a compatible Stata file containing this year's survey data. First, extract the metadata: extract_metadata last-year.dta survey-metadata.json Now apply it to this year's data, which is stored in a CSV file: readstat this-year.csv metadata.json this-year.dta The first line of the CSV file should contain column names which match the column names in last-year.dta. If everything went well, your new binary data set is now stored in this-year.dta. OPTIONS None.
