Try this.

1) Select the field(s) in the Excel spreadsheet.

2) In Corel, select "Edit" > "Paste Special"

3) Select "Picture (Enhanced Metafile)"

This will paste in a grouped object which you may then ungroup and manipulate at will.

Simply copying and pasting the cells from Excel to Corel will only produce a non-editable object in Corel. When this object is doubled clicked it invokes Excel allowing changes to the data. Once saved, the changes are updated to your object in Corel.

I hope this works. Good luck!
