【问题描述】：

我正在使用此功能从数据库中导出数据：

def export_packing_xls(request):
    response = HttpResponse(content_type='application/ms-excel')
    file_name = "packing_list_"+str(datetime.now().date())+".xls"
    response['Content-Disposition'] = 'attachment; filename="'+ file_name +'"'
 
    wb = xlwt.Workbook(encoding='utf-8')
    ws = wb.add_sheet('Packing List')

    date1 = request.GET.get('exportStartDate')
    date2 = request.GET.get('exportEndDate')
 
    # Sheet header, first row
    row_num = 0
 
    font_style = xlwt.XFStyle()
    font_style.font.bold = True
 
    columns = ['Ref Number', 'Description of Goods','QTY','Gross WT',]
 
    for col_num in range(len(columns)):
        ws.write(row_num, col_num, columns[col_num], font_style)
 
    # Sheet body, remaining rows
    font_style = xlwt.XFStyle()
 
    rows = Booking.objects.filter(created_at__range =[date1, date2]).values_list('booking_reference', 'product_list', 'gross_weight',)
    for row in rows:
        row_num += 1
        for col_num in range(len(row)):
            ws.write(row_num, col_num, row[col_num], font_style)
            print(row[col_num][1][:4])

    wb.save(response)
    return response

我收到这种：

Ref Number  Description of Goods    QTY Gross WT
AWBO114 [{"id":1,"Name":"T shirt","Quantity":"10","Weight":"2","WeightTypes":"KG","TotalWeight":"20","CustomsCharge":"20.0","Discount":"12","Subtotal":"188"}]  12  22
AWBO117 [{"id":1,"Name":"T shirt","Quantity":"15","Weight":"45","WeightTypes":"KG","TotalWeight":"675","CustomsCharge":"20.0","Discount":"45","Subtotal":"255"}]    45  455
AWBO118 [{"id":1,"Name":"Fan","Quantity":"12","Weight":"12","WeightTypes":"KG","TotalWeight":"144","CustomsCharge":"100.0","Discount":"12"},{"id":2,"Name":"T shirt","Quantity":"22","Weight":"5","WeightTypes":"KG","TotalWeight":"110","CustomsCharge":"20.0","Discount":""}] 15  15
AWBO121 [{"id":1,"Name":"T shirt","Quantity":"12","Weight":"12","WeightTypes":"KG","TotalWeight":"144","CustomsCharge":"20.0","Discount":"12","Subtotal":"228"}]    0   20
AWBO122 [{"id":1,"Name":"T shirt","Quantity":"12","Weight":"12","WeightTypes":"KG","TotalWeight":"144","CustomsCharge":"20.0","Discount":"12","Subtotal":"228"}]    12  12

但我想为“商品描述”列一个清单，就像这样：

如何在 Excel 文件中列出我的 JSON 数据？

如果你有什么想知道的，请在评论区告诉我。谢谢。

【问题讨论】：

你试过write_merge吗？ stackoverflow.com/questions/19672760/…
您需要遍历第 2 列的 json，以便您可以浏览详细信息
@Walucas 我如何迭代 Json 数据？我尝试使用 row[col_num]['Name'] 这个命令，但是如果我使用 row[col_num][0] 这个命令 'float' 对象不可下标，它的 字符串索引必须是整数请问？
@JoseAntonioCastroCastro 是的，我已经看到了，但我无法从 Json 列表中获得价值。
@MdAzharulIslamSumon 我将其添加为答案

【解决方案1】：

要从字符串遍历 json，你需要这个：

import json

myJson = json.loads(row[col_num])
#now you can do:
print(myJson['Name'])

【讨论】：

感谢您的回答，但我必须使用myJson = json.dumps(rows[col_num]) neJson = json.loads(myJson) print(neJson[2])
