Hi,

It does take nearly 30 minutes to finish scanning these two sheets
https://app.box.com/s/zkm75d29hef82zct7bkw784iro8kmn64

using such codes
                    foreach (Excel.Worksheet sheet in Book0.Worksheets)
                    {
                        Excel.Range usedRange = sheet.UsedRange;

                        RowID++; Worksheet0.Cells[RowID, 1] = "^^^^" + sheet.Name + "^^^^"; RowID++;

                        foreach (Excel.Range row in usedRange.Rows)
                        {
                            RowID++;
                            for (int i = 0; i < row.Columns.Count; i++)
                                /*if (!string.IsNullOrEmpty(rowData[i]))
                                    j = 0;
                                else
                                    j++;*/

                                if (!string.IsNullOrEmpty(Convert.ToString(row.Cells[1, i + 1].Value2)))
                                {
                                    Worksheet0.Cells[RowID, i + 1] = row.Cells[1, i + 1].Value2;
                                    Worksheet0.Cells[RowID, i + 1].Interior.Pattern = row.Cells[1, i + 1].Interior.Pattern;
                                    ...
Why? Any other way to efficiently/quickly read the attached two Excel Worksheets?
