JASP can open the following file types:
- .csv, .tsv, and .txt (any text files with comma/semicolon/colon/tab separated columns)
- .sav and .por (SPSS files)
- .sas7bdat (SAS files)
- .ods (Open Document Spreadsheet format, used by software such as OpenOffice, LibreOffice, and Excel)
- .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.
