Sorry, but without a way to bring data in or out this app looks unfinished.

Just to make it clear, it's not that hard to do it. Here's a very basic example in javascript that took roughly 3 hours of time (this parses enough of the XLSX format to generate a CSV output with a few integers and strings; requires html5 file API to be able to manipulate the file in your browser. Best results on chrome):

There's an XLS version as well (doesn't support the full panoply of features):
No reason to release the product without having the data hooks in place. We don't need more silos.
It obviously should come soon, though, and my expectation would be to see it in a free update.
