Thanks!

Welcome to the PF. I'm not sure I understand your question. What format is the data in? Is it already in Excel in two columns? Or is it in a clear text file in CSV or some other format?

And you want the output of your program to be what? An Excel spreadsheet with an interpolated y data column next to some pre-set x data (regular interval) column?

Thanks!

If you have the math worked out then most of the work will be in making the program interface. Is that what you need help with? If so, it sounds more like a programming issue. If so, then what language are you familiar with?
