It is not the heighth or width that is the issue
Excell lets you merge cells but then doesn't let you do much with the merger.

I woul dtry to see if you can format without merging. and then copy.

When I try to paste values of a merged cell into another workbook with

the columm width to be sure they are the same size as the original copied
cells
