Donor lists

I’m re-designing a site. They have a Donor’s page that lists every person who has donated. The donors’ names are first categorized by range of donation, and then alphabetically within those categories. Right now they update the lists by hand, but really want to find a way to just import to the page from an Excel document, and to also make the page more attractive. Is there a way to do something like this? I’ve been searching for plugins but can’t find anything that does what they want. Thank you.
