如何在 excel 的一个单元格中插入 pandas 数据帧（使用 openpyxl），其中的值将用逗号分隔？

Question

I would like to insert a pandas data frame in one cell in excel (using openpyxl), where the values of the data frame will be separated with comma. Until now I have achieved to print the data frame in excel but in multiple cells, as it is presented in the following script and table. Moreover, in the last figure, the table that I want to print in excel is presented.

import pandas as pd
from openpyxl import load_workbook 
from openpyxl.utils.dataframe import dataframe_to_rows

wb = load_workbook('test.xlsx')
ws = wb['Sheet1'] 
df = pd.DataFrame({'Data': [1, 2, 3, 4, 5, 6]}) 
df_transpose=df.T
rows_materials= dataframe_to_rows(df.T, index=False,header=False)

for r_idx_materials, row in enumerate(rows_materials, 1):
    for c_idx_materials, value in enumerate(row, 1): 
         ws.cell(row=r_idx_materials, column=c_idx_materials, value=value)

wb.save('test.xlsx')

Answer 1

You can pass the contents of the list in as a string like this

wb = load_workbook(r'C:\temp\temp.xlsx')
ws = wb['Sheet1'] 
my_list = ["1, 2, 3, 4, 5, 6"]
df = pd.DataFrame({'Data': my_list}) 
df_transpose=df.T
rows_materials= dataframe_to_rows(df.T, index=False,header=False)

for r_idx_materials, row in enumerate(rows_materials, 1):
    for c_idx_materials, value in enumerate(row, 1): 
         ws.cell(row=r_idx_materials, column=c_idx_materials, value=value)

wb.save(r'C:\temp\temp.xlsx')

Output
