openpyxl 把列变成一行

Question

我有 excel 工作簿 origin.xlsx，其中有 3 个工作表。我想遍历所有工作表中特定列的所有单元格（例如，列 "A"），复制每个单元格的值并将所有单元格（一个接一个）传递到另一个工作簿的一行中 destination.xlsx.即从多个工作表的列中生成一行。但是，我的代码仅将 origin.xlsx

中 3 列中每一列的最后一个单元格的值放在一行中

import openpyxl
wb = openpyxl.load_workbook('origin.xlsx')
g_sheet=wb.sheetnames
print(g_sheet)
for i in g_sheet:
    print(i)
    ws = wb.get_sheet_by_name(i)
    print(ws)
    for row in range(1, ws.max_row + 1):
        for column in "A":
            cell_name = "{}{}".format(column, row)
            print(ws[cell_name].value)
        wb = openpyxl.load_workbook('destination.xlsx')
        wss = wb.active
        wss.cell(row=1, column=ws.max_column + 1, value=ws[cell_name].value)
        wb.save(filename)

Answer 1

您可以在开始时使用单独的打印机打开源文件和目标文件，遍历源中的工作表并将所选 column 的所有 row 值附加到目标文件，如下所示，

# _s denotes source/origin and _d -> destination
wb_s = openpyxl.load_workbook('origin.xlsx')

# create worrkbook 'destination.xlsx' if it does not exist
wb_d = openpyxl.Workbook()
wb_d.save('destination.xlsx')
ws_d = wb_d.active

row_num = 1
for sheet in wb_s.sheetnames:
    ws_s = wb_s[sheet]
    for cell_s in ws_s['A']: # if 'A' is the column to copy
#         if cell_s.row > 1:    to avoid  writing column headings  to destination file if source column has column heading
        ws_d.cell(row=row_num, column=1, value=cell_s.value) # column =1 will write the selected values to column 'A
        row_num+=1
wb_d.save('destination.xlsx')

Answer 2

from openpyxl import load_workbook, Workbook
wb1 = openpyxl.load_workbook('origin.xlsx', read_only=True)
wb2 = Workbook()

ws1 = wb1.active
ws2 = wb2.active

cols = ws1.iter_cols(min_col=1, max_col=1, values_only=True)
for col in cols:
    ws2.append(col)

openpyxl 把列变成一行

openpyxl turn column into a row
