How to import Excel file to CCK nodes? Is there a way to import a Excel file into CCK nodes? 


Each Excel file contains only a single sheet
First row of there sheet is header
Data are only strings, numbers, and decimal numbers
It's a daily task which will be performed by a user
You'll probably have to save your Excel file to CSV format to be able to import more easily. Two options:


Node Import: You can certainly import CSVs with this, and I've used it successfully for huge spreadsheets before -- it's powerful, helpful and quite easy.
Feeds: Much more complex to get going than Node Import, but Feeds can in theory do everything you want and much more. Can also update existing nodes.


Either of these will allow you to import CSV data (exported from your Excel document) to nodes and their CCK fields.
