Indexing cont of Jupyter notebooks (*.ipynb)

Hi all!

I tried to organize my python code with DT3 to look up faster for code snippets which works with .py files but not with notebook files (*.ipynb).
Basically they are json-files with an other file ending.

Has anyone a similar scenario or a solution suggestion for these kind?

Best regards,

One possibility might be to change the extension to .json before importing.
