How many rows are there in an excel worksheet?

You mean on a sheet you can print on one page? Mostly its unlimited on the computer. It will do as many as you like. Printing you just need to set the print area.

I get an unexpected error when I try to publish a list.

When you publish a list, unexpected errors may occur for a number of reasons.

You may not be able to access the Microsoft Windows SharePoint Web site. The URL specified for the SharePoint site may be incorrect or an administrator may have configured the SharePoint site to deny access.
The name of the list may be too long. Give the list a shorter name before trying to publish it again.
You may have cancelled the publish operation while data was being transferred to the SharePoint site.
There may be a version conflict between Microsoft Excel and the SharePoint site.
There may have been a schema conflict between the list in Excel and the list on the SharePoint site.
The list may have too many rows. The maximum row limit is 65,534
