Great question! I too will wait for a better answer. But here goes.....

The pickit2 also has a uart tool. If you can spare the pre-defined pin, you could have the pic device read out its own eeprom data in coma delimited form (using serout), then click the log to file button, then open up the comma delimited file in excel.

Not too bad, but would be nice not to have to add serout. Might need to write a visual basic program to parse it?
