Lets take a sample Excel workbook with some value in it for the program. This data structure could have sheetData[x][y] for the cell at column x and row y. from openpyxl import load_workbook # excel excel = load_workbook(' excel ') # sheet sheet = excel[' sheet '] # # "A" for row in sheet.iter_rows(): for cell in row: if 'A' in cell.coordinate: # print (cell.coordinate, cell.value) # . for rowNum in range(2, sheet.max_row):# skip the first row, produceName = sheet.cell(row=rowNum, column=1).value, sheet.cell(row=rowNum, column=2).value = PRICE_UPDATES[produceName], italic24Font = Font(size=24, italic=True), fontObj1 = Font(name='Times New Roman', bold=True), sheet['A1'] = 'Twelve cells merged together.

print('Reading rows')
component of a worksheet. print(cellObj.coordinate, cellObj.value)
