Question

Primer：我非常 Python的新手。

我正在制作一些Google表格数据，并用它创建.xlsx表格。通过下面的代码，我可以让Python读取数据并将其放入数组中。但是，我似乎无法弄清楚如何让openpyxl成功地将其写入文档。我假设它与尝试编写数组有关，而不是迭代出现的行。

非常感谢您提供的所有帮助/建议。

尝试运行时出现以下错误：

使用Pandas代码更新：

当将index标志保留为true（未编辑）时，这是数据的布局：

"""
Using pandas and dataframes. For writing large amounts of data, this is probably the best way. 
"""
df=DataFrame(data=values)
df.to_excel('Pandas.xlsx')

将index标记标记为false时，数据的外观如下：

"""
Using pandas and dataframes. For writing large amounts of data, this is probably the best way. 
"""
df=DataFrame(data=values)
df.to_excel('Pandas.xlsx', index=False)

更新2：已解决的解决方案！ Zyd和Ben.T的以下代码完全解决了我的问题。

"""
Using pandas and dataframes. For writing large amounts of data, this is probably the best way. 
"""
df=DataFrame(data=values)
df.to_excel('Pandas.xlsx', header=False, index=False)

谢谢大家的帮助！

Answer 1

这可能不正确，但我的回答有点过于无法发表评论。

你在做什么：

if not values:
    print('No data found.')
else:
    wb = Workbook()
    ws = wb.active  
    # Add new row at bottom
    ws.append([values])
    wb.save("users.xlsx")  # Write to disk

我会尝试

import pandas
if not values:
    print('No data found.')
else:
    dataframe = pandas.DataFrame([values])
    dataframe.to_excel('excel_out.xlsx')

Answer 2

似乎名为values的变量是一个列表，其中包含Google电子表格每行的列表。我试过了：

import openpyxl
# to recreate a list of list
list_input = [['one','two'],['second row','with',14]]

wb = openpyxl.Workbook()
ws = wb.active
ws.append(list_input)
wb.save("test.xlsx")

我得到的错误与您的更新相同。

将行ws.append(list_input)替换为

for row in list_input:
    ws.append(row)

我的代码有效，所以我会用

替换你的行ws.append([values])

for row in values:
    ws.append(row)

希望对你有所帮助。
