如何使用 python 更改 excel 中的列格式

Question

我想用“openpyxl”方法将特定的行和列一个 sheet 复制到另一个。但我的主要 excel 文件是 .xlsb 文件，“openpyxl”不支持 .xlsb file.So 我构建的方式很复杂。（* 根据公司规定，我无法更改 Microsoft Excel 的 .xlsb）。

main document.xlsb file->temporary document.xlsx->my analyze document.xlsx

-首先，我将数据格式 .xlsb 更改为 .xlsx pandas。

-之后，从临时 document.xlsx，我使用 openpyxl 方法获取特定的列和行并粘贴到我的分析 document.xlsx

-我的问题是：我想将 D 列格式从“通用”更改为“短期”，我是 Python 的初学者。你能帮我了解一下代码吗？另外，如果我可以更改“.xlsb 到 .xlsx 转换期间”中的格式单元格，也许我可以从用户那里获取输入：“您想追加哪个日期 'my analyse document.xlsx?'”

'main document.xlsx'

'temporary document.xlsx'

'my analyse document.xlsx'

import pandas as pd
import openpyxl

df = pd.read_excel("main document.xlsb",sheet_name="Data", engine="pyxlsb")
df.to_excel("temporary document.xlsx")

#! Python 3
# - Copy and Paste Ranges using OpenPyXl library

# Prepare the spreadsheets to copy from and paste too.

# File to be copied
wb = openpyxl.load_workbook("temporary document.xlsx")  # Add file name
sheet = wb["Sheet1"]  # Add Sheet name

# File to be pasted into
template = openpyxl.load_workbook("my analyse document.xlsx")  # Add file name
temp_sheet = template["Sheet2"]  # Add Sheet name


# Copy range of cells as a nested list
# Takes: start cell, end cell, and sheet you want to copy from.
def copyRange(startCol, startRow, endCol, endRow, sheet):
    rangeSelected = []
    # Loops through selected Rows
    for i in range(startRow, endRow + 1, 1):
        # Appends the row to a RowSelected list
        rowSelected = []
        for j in range(startCol, endCol + 1, 1):
            rowSelected.append(sheet.cell(row=i, column=j).value)
        # Adds the RowSelected List and nests inside the rangeSelected
        rangeSelected.append(rowSelected)

    return rangeSelected


# Paste range
# Paste data from copyRange into template sheet
def pasteRange(startCol, startRow, endCol, endRow, sheetReceiving, copiedData):
    countRow = 0
    for i in range(startRow, endRow + 1, 1):
        countCol = 0
        for j in range(startCol, endCol + 1, 1):
            sheetReceiving.cell(row=i, column=j).value = copiedData[countRow][countCol]
            countCol += 1
        countRow += 1


def createData():
    print("Processing...")
    selectedRange = copyRange(2, 2011, 183, 2274, sheet)  # Change the 4 number values (startCol, startRow, endCol, endRow, sheet)
    pastingRange = pasteRange(2, 4573, 182, 4836, temp_sheet, selectedRange)  # Change the 4 number values (startCol, startRow, endCol, endRow, sheet)
    # You can save the template as another file to create a new file here too.s
    template.save("my analyse document.xlsx")
    print("Range copied and pasted!")

go= createData()

Answer 1

是的，看看这里 docs:

import xlsxwriter

workbook = xlsxwriter.Workbook('your_file.xlsx')
worksheet = workbook.add_worksheet()

cell_format05 = workbook.add_format()
cell_format05.set_num_format('mm/dd/yy')
worksheet.write(5, 0, 36892.521, cell_format05)  # output -> 01/01/01

# untested code for you, get your cells into column_D8_downwards array
# this is rather a structural code, not functional!
row = 0
for cell in column_D8_downwards:
    worksheet.write(row, 'D8', cell, cell_format_05)
    row=+1

workbook.close()

因此遍历列中的所有单元格（D8 向下）并将旧值写入新格式的单元格。

Here is a good example.

您也可以在 xlrd 的帮助下使用 pandas.DataFrame 读取数据后执行相同的操作：

import xlrd
import pandas as pd

df = pd.read_csv('Your_File.csv')
df = df[6:].reset_index()
df.columns = df.iloc[0]

df['Date'] = df['Date_Int'].apply(lambda x: xlrd.xldate.xldate_as_datetime(x, 0))

print(df)

   TARİH       Date
0     43891 2020-03-01
1     43892 2020-03-02
2     43893 2020-03-03
3     43894 2020-03-04
4     43895 2020-03-05

此外，您可以根据需要更改日期格式。

Answer 3

问题解决的很简单，解决的时候惊呆了

1-打开"my analyse document.xlsx"

2-Select整个"D"列

3-单击主页按钮

4-格式单元格-> 短日期

即使我用 python 更新 excel 数据，列格式类型也没有改变。
