Hi,
Welcome to Microsoft Community.
A quick question,
Do you want the Excel spreadsheets to be inserted in respective OneNote pages separately?
If yes, you can do this using Print out option or by creating a separate workbook for each spreadsheets as you tried. OneNote always inserts spreadsheets in a single OneNote page.
You can post your feedback and findings in the following link.
