Randall Parker inspired spreadsheets in Max?

Hello all,
I was reading the recent interview with Randall Packer and Craig Roche and was very impressed with their use of spreadsheets to control show data. Mr Roche mentions that it was achieved using tab separated text files and JS parsing.
I would love to use something like this, but unfortunately have no js experience.

I did some searching of the forums and the closest thing I could find was Adam Murray's 'cellblockcsv.js' object (http://github.com/adamjmurray/max_csv_tools), which works very well for exporting tabular data but is unable to import it.

Does anyone know how to go about importing spreadsheet information into max?

Ideally I could import it, edit it and export it all from the same jit.cellblock like interface.
