Thanks for the comments
@kriggy, It does nothing that the software you mention doesn't also do. However, in the event your university doesn't have a site license for those software suites, this is a cheap, short-term solution.
@hypervalent_iodine, it is all manual entry. So it will handle it as well as you can
You'll enter the peaks manually, so as long as your spectrum is resolved well enough to get the individual peaks, it will handle them just fine.
Let me know if you have any more questions, friends!
