[Updated 6 Aug 2010: Moved download links. Put correct sample file in sample zip.]
Lately we've been using JSON as our text-based interchange format of
choice internally. While most of our tools are internal and save this
data in a way that's invisible to the user, we still do work with a lot
of external tools. For better or worse one of those tools is Excel.
Giac Veltri (Engine Programmer) has put together a JSON exporter for
Excel and short presentation that give a bit of background on the
plugin. This plugin might not do exactly what you want, but it could be a good place to start if you're also looking to export JSON from Excel.
Included here are Giac's Excel plugins for Excel 2007 (xlam) and Excel 97-2003 (xla) and sample data and the generated JSON.
Have fun!
