JASP can open the following file types:

  1. .csv, .tsv, and .txt (any text files with comma/semicolon/colon/tab separated columns)
  2. .sav and .por (SPSS files)
  3. .sas7bdat (SAS files)
  4. .ods (Open Document Spreadsheet format, used by software such as            OpenOffice, LibreOffice, and Excel)
  5. .dta (Stata files)

Not without considerable effort. When JASP was first developed, our focus was on producing a GUI that would retain the desirable properties of syntax (such as reproducibility) without requiring or producing syntax itself. We believe we did a decent job on the GUI, but we recognize that some users still like easy access to the R code. Adding this functionality to JASP has been one of our top priorities and we hope to add it to JASP in the near future.
