Stata Do File Exporter provides a context menu and template for exporting a jupyter notebook with Stata kernel, to a do-file with all markdown and code ready to be executed at the Stata GUI or console.
To install the exporter, write:
pip install Stata-Do-file-Exporter
Your jupyter notebook should not be available for export from the File -> Download as menu.
Currently, translation of stata_kernel magics are not supported.
