我想用Python导出Excel文件。我正在发送csv数据到我的代码和制作Excel文件。文件已成功保存到特定位置，并带有数据。但它不显示为下载，所以用户知道文件是下载的。在

有一些额外的代码可以对Excel工作表中的某些列进行验证：def downloadUploadExclusionDetailReport(request):

csv_data=request.GET.get('csv_data')

createExcel(csv_data)

return HttpResponse(csv_data, content_type="application/text")

def createExcel(data):

wb=openpyxl.Workbook()

WorkSheet=wb.create_sheet(title="report")

data=data.split('|')

row_count=1

col_count=1

for row in data:

row=row.split(',')

col_count=1

for cell in row:

WorkSheet.cell(row=row_count, column=col_count).value=cell

col_count=col_count+1

row_count=row_count+1

########Add Checked / Unchecked

dv1 = DataValidation(type="list", formula1='"checked,unchecked"', allow_blank=False)

# Optionally set a custom error message

dv1.error ='Your entry is not in the list'

dv1.errorTitle = 'Invalid Entry'

# Optionally set a custom prompt message

dv1.prompt = 'Please select from the list'

dv1.promptTitle = 'List Selection'

# Add the data-validation object to the worksheet

WorkSheet.add_data_validation(dv1)

dv1.ranges.append('A2:A1048576')

########Add Exclusion Reason List

dv2 = DataValidation(type="list", formula1='"limited_by_machine_size,fixed_cycle_time,moq_cannot_be_renegotiated,lt_cannot_be_renegotitaed,vendor_refused_to_be_vendor_consignment,quality_issue_dont_have_short_term_solution,fix_import_export_time,special_requirement_from_customer,new_product,others"', allow_blank=True)

# Optionally set a custom error message

dv2.error ='Your entry is not in the list'

dv2.errorTitle = 'Invalid Entry'

# Optionally set a custom prompt message

dv2.prompt = 'Please select from the list'

dv2.promptTitle = 'List Selection'

# Add the data-validation object to the worksheet

WorkSheet.add_data_validation(dv2)

dv2.ranges.append('B2:B1048576')

########Add Action Category List

dv3 = DataValidation(type="list", formula1='"Max_Benefit,MTO-MTS,Vendor_Consignment,Lead_Time,Prod_Cycle_Time,MOQ,Batch_Size,Quality_Issue"', allow_blank=True)

# Optionally set a custom error message

dv3.error ='Your entry is not in the list'

dv3.errorTitle = 'Invalid Entry'

# Optionally set a custom prompt message

dv3.prompt = 'Please select from the list'

dv3.promptTitle = 'List Selection'

# Add the data-validation object to the worksheet

WorkSheet.add_data_validation(dv3)

dv3.ranges.append('C2:C1048576')

wb.save('C:\Python27\henkel_supply_chain\\fuploads\Template Ver 2.xlsx')
