Pasting from Excel into Glide doesn't work

When I paste from an Excel table into a Glide table, the result is unexpected. The empty cells do not remain empty and characters are introduced, such as spaces or line-breaks. These characters also appear when the original cell begins with the text ‘I…’, e.g. ‘I am learning to live’. Characters are randomly added after ‘I’.

Not sure what is going on. My excel table is most definitely free from these spurious characters…

Any thoughts?

Simon.
