Hi UKYank66,
As per your description, it seems you are loss formatting when you copy some formula/text from Excel to OneNote.
First, may I know are you using OneNote 2016 or OneNote windows 10 app from copy Excel file to OneNote.
Also, please confirm Which option did you select in OneNote when pasting the data? Please check the screenshot below for reference.
I’ll suggest you try Keep source formatting option when pasting the content into OneNote 2016 or OneNote Windows 10 app.
