This question is quite similar to the one asked here. But the answer given suggests copying the format along with the data. I have a excel sheet (.xlsx) that I generate usin
So you want to copy format from first cell and apply it to all your sheet.
There is a way to process:
Range sourceRange = sheet.get_Range("A1:A1");
sourceRange.Copy();
Range last = sheet.Cells.SpecialCells(XlCellType.xlCellTypeLastCell, Type.Missing);
Range destinationRange = sheet.get_Range("A1", last);
destinationRange.PasteSpecial(XlPasteType.xlPasteFormats);
