Are you saying you have ZK Spreadsheet import issue with your xls sheet? Since ZK Spreadsheet supports xlsx files better, please save your xls sheet as xlsx and import again. If it doesn't resolve your issue, please provide your project and file and contact ZK support.

Yes, we got zk spreadsheet import issue. I checked with xlsx also, we are getting the same problem.

You can first download the latest ZK Spreadsheet EE Demo App (2nd item in the ZK Spreadsheet Download page) and try to import the xlsx file. If it doesn't work then it is most likely something in the file was not supported or corrupted. Send the file to info AT zkoss DOT org and we can take a look.
