CED2AR can automatically create DDI2.5 codebooks from SPSS and STATA (Versions 8 thru 13) datasets. Codebooks are created by just uploading supported datasets into CED2AR.
CED2AR cannot convert SAS datasets. We suggest to convert SAS to SPSS for uploading (as of 2017, there are issues with the converted STATA datasets, though native STATA datasets work just fine). However, for future reference, SAS to STATA conversions are also available.
Recommended way to convert SAS dataset into SPSS is ...
SAS2TRANSPORT/sas2transportdataset.sas
SAS2SPSS/sastransport2spss.sbs
This is a one step process to convert SAS to SPSS using a SAS script. With this type of conversion, CED2AR is unable to create variable level summary statistics. This option works if variable level summary statistics are not important.
The direct conversion by SAS creates a valid STATA file that is not successfully read by CED2AR. At this time, the reason is unknown. Post-processing using STATA solves the problem.
With the following post-processing code, the generated Stata file is readable by CED2AR:
