How to reed data from 18F4550 EEPROM into EXCEL via PC USB interface?

I was going to suggest that, But you would have to get written permission for bussiness use has you can us it and alter it for free for private use. If i remember there is one file that cannot be altered due to copyrights.
May be worth e-mailing them to ask and see what they say

Thanks, Chuck for ideas. Are you referring to Parralax or Windmill?

I was referring to Parralax has this is a freeware not sure about the windmill software.
I've used the Parralax many of times and it really easy to use.

Thanks, Chuck. As I have said before, however, I must use it on a USB intereface for this particular application. Have you (or anyone else that might answer) ever been able to get Parralax to work with a USB interface between the PC and the PIC?? If I can verify that is doable I am going to give it a try.

From what I hear, USB-to-serial adapters work fine with PLX DAQ, BUT you have to make sure Windows assigns a lower com number (1 to 4) to the virtual serial port.

Sorry I have not tired the USB way, But I just used an RS232 chap and uploaded it via USB-to-serial cable and this works spot on. This was becasue the laptop does not a a serial port on it.
I have treid to do a search for usb into excel but never found anything, I shall carry and look and have ago at doing my own has USB is the way forwardm I susspose it easy to so once you have mastered it.

USB is not my forte (yet!), but from what little I understand (Bruce, Darrel or any of the other Gurus can confirm or rubbish this), if you use CDC descriptors on the pic side it would be equivalent to using a RS232-to-serial. Then, you dont need to worry about inputing data from USB into Excel; just assign a low com port to the virtual connection and Excel wouldnt even know the data is coming over USB, not the serial port.

I am not a guru but you are correct.
