我使用pandas以下列方式写入excel文件:

import pandas

writer = pandas.ExcelWriter('Masterfile.xlsx') 

data_filtered.to_excel(writer, "Main", cols=['Diff1', 'Diff2'])

writer.save()

Masterfile.xlsx已包含许多不同的选项卡.

Pandas正确写入"Main"表,不幸的是它还删除了所有其他选项卡.

我目前有这个代码.它完美地运作.

它循环遍历文件夹中的excel文件,删除前两行,然后将它们保存为单独的excel文件,并将文件作为附加文件保存在循环中.

目前,每次运行代码时附加的文件都会覆盖现有文件.

我需要将新数据附加到已经存在的Excel工作表的底部('master_data.xlsx)

dfList = []
path = 'C:\\Test\\TestRawFile' 
newpath = 'C:\\Path\\To\\New\\Folder'

for fn in os.listdir(path): 
  # Absolute file path
  file = os.path.join(path, fn)
  if os.path.isfile(file): 
    # Import the excel file and call it xlsx_file 
    xlsx_file = pd.ExcelFile(file) 
    # View the excel files sheet names 
    xlsx_file.sheet_names 
    # Load the xlsx files Data sheet as a dataframe 
    df = xlsx_file.parse('Sheet1',header= None) 
    df_NoHeader = df[2:] 
    data = df_NoHeader 
    # Save individual dataframe
    data.to_excel(os.path.join(newpath, fn))

    dfList.append(data) 

appended_data = …

我正在使用xlsxwriter写入Excel工作表.我面临的问题是:当文本超过单元格大小时,它会被隐藏.

import xlsxwriter

workbook = xlsxwriter.Workbook("file.xlsx")
worksheet1 = workbook.add_worksheet()

worksheet1.write(1, 1,"long text hidden test-1" )
worksheet1.write(2, 1,"long text hidden test-2")
worksheet1.write(3, 1,"short-1")
worksheet1.write(4, 1,"short-2")
worksheet1.write(1, 2,"Hello world" )
worksheet1.write(2, 2,"Hello world")
worksheet1.write(3, 2,"Hello world")
worksheet1.write(4, 2,"Hello world")

workbook.close()
