Description Bastián Díaz 2014-11-09 18:28:55 UTC
*.sav & *.zsav files,These are files used by the SPSS statistical software. It would be a great improvement Libo Calc can import these files and to export them in ODS. Moreover, these data can be used by Calc to perform basic statistical analysis (from 4.3), which is ideal for use by students.

I opened a discussion document liberation mailing list

As I said about adding support for the DTA format:
* How popular are SAV and ZAV file formats?
* How many users of SPSS will want to import their data into LibreOffice?

As always, providing a spec and test files is greatly appreciated!

Unlike file format Stata, SPSS SAV format is very popular (ZSAV is zcompressed SAV version), and is considered a standard for this type of file.
Its popularity leads to public and private institutions to publish databases on this file format, and not always using a data format separated by commas or tabs.

In UK dating service, present a list of formats that can be found in the data : http://ukdataservice.ac.uk/help/faq/formats.aspx

Consider that for these files, there is no substitute OpenSource, and export it to another format leads to some loss of data (ex. metadata variables as labels), but his data matrix remains intact. It is always good to use spreadsheets, I pert export to ODS format does not exist transparently. (Free alternatives as PSPP or R use this file format and can import data from ODS spreadsheet).

In answer question, few users of SPSS will export your data to LibreOffice, but can be many LibreOffice users who want to use their data are in SPSS format (downloadable as a public database).
