從數據框字典創建 Excel 表格

Question

我有數據框字典。

dd = {
'table': pd.DataFrame({'Name':['Banana'], 'color':['Yellow'], 'type':'Fruit'}),
'another_table':pd.DataFrame({'city':['Atlanta'],'state':['Georgia'], 'Country':['United States']}),
'and_another_table':pd.DataFrame({'firstname':['John'], 'middlename':['Patrick'], 'lastnme':['Snow']}),
     }

我想創建一個 Excel 文件，其中包含從這些數據幀創建的 Excel 表對象。 每個表都需要位於單獨的選項卡/工作表上，並且表名稱應與數據框名稱匹配。

這可能與Python有關嗎？

到目前為止，我只能正常將數據導出到 Excel，而無需使用xlsxwriter轉換為表格

writer = pd.ExcelWriter('Results.xlsx', engine='xlsxwriter')

for sheet, frame in  dd.items():
    frame.to_excel(writer, sheet_name = sheet)

writer.save()

Answer 1

要從 Pandas 編寫多張工作表，請使用openpyxl庫。 此外，為防止覆蓋，請在每次更新之前設置工作簿表。

試試這個代碼：

import pandas as pd
import openpyxl

dd = {
'table': pd.DataFrame({'Name':['Banana'], 'color':['Yellow'], 'type':'Fruit'}),
'another_table':pd.DataFrame({'city':['Atlanta'],'state':['Georgia'], 'Country':['United States']}),
'and_another_table':pd.DataFrame({'firstname':['John'], 'middlename':['Patrick'], 'lastnme':['Snow']}),
}

filename = 'Results.xlsx'  # must exist

wb = openpyxl.load_workbook(filename)

writer = pd.ExcelWriter(filename, engine='openpyxl')

for sheet, frame in  dd.items():
    writer.sheets = dict((ws.title, ws) for ws in wb.worksheets) # need this to prevent overwrite
    frame.to_excel(writer, index=False, sheet_name = sheet)

writer.save()

# convert data to tables
wb = openpyxl.load_workbook(filename)
for ws in wb.worksheets:
   mxrow = ws.max_row
   mxcol = ws.max_column
   tab = openpyxl.worksheet.table.Table(displayName=ws.title, ref="A1:" + ws.cell(mxrow,mxcol).coordinate)
   ws.add_table(tab)

wb.save(filename)

輸出
