JupyterLab - Get JSON of current notebook

[Sterling Paramore]

Is there a way to get the JSON representation of a notebook that is currently open that could be passed to nbformat?

I'm trying to create a pandas dataframe from a markdown cell with a table in it.  This is kind of a hack workaround for having some way of easily editing and pretty-printing dataframes within a notebook.

Thanks,

Sterling

Thanks Brian,

I guess I wasn't clear enough.  I want to be able to execute code within a cell that gets the JSON for the current notebook.  Here's the best I can do currently.  It almost works, but I don't know how to get the name of the current notebook:

```

import nbformat

fp = open('TheNameOfThisWorkbook.ipynb')

nb = nbformat.read(fp, 4)

for cell in nb['cells']:

    print('---')

    print(cell)

```

As far as I know, the kernel doesn't know anything about the open notebook. The notebook file might not even be on the same machine as the kernel.

But, dataframes should already be display'able in a nice way in the notebook. Is there something missing from the default functionality?

Yeah, I'd like the ability to edit dataframes directly in a nicely formatted table.  qGrid seemed to work well in Jupyter notebooks, but I fought for several hours trying to get it working in Lab to no avail. At pyData Seattle I recall hearing something about lack of support for some JavaScript output so I thought that might be the reason.
