Javier Toledo Rivero,
I'm not sure what you mean by "unit price analysis" as it applies to resources, but generally, yes, if resource data is in Excel, it can be imported either via an import map or with a VBA macro.
If you can elaborate in more detail, then we can give a more definitive answer. An example would help.
Also, please tell us what version of Project you are using (i.e. standalone desktop, Project Online, Project for the Web, etc.).
