python處理excel實例

1、提取word內的所有表格內容，寫到excel內

安裝上python-docx

# coding=utf-8
from docx import Document
from xlwt import Workbook

# 初始化路徑
xl_path = f"./path/excel.xls"
word_path = f"./path/word.doc"

# 讀word
doc = Document(word_path)
tables = []
for table in doc.tables:
    table_temp = []
    for row in table.rows:
        row_temp = []
        for cell in row.cells:
            row_temp.append(cell.text)
        table_temp.append(row_temp)
    tables.append(table_temp)
tables_2 = list(filter(None, tables))
# 寫到表裏
Sheet_index = 0
workbook = Workbook(encoding='utf-8')
for table in tables_2:
    worksheet = workbook.add_sheet('sheet' + str(Sheet_index), cell_overwrite_ok=True)
    Sheet_index = Sheet_index + 1
    for rows in table:
        r = table.index(rows)
        for cell in rows:
            c = rows.index(cell)
            worksheet.write(r, c, cell)
workbook.save(xl_path)

2、多個字段名一樣的excel合併成一個

import pandas as pd

xl_path = r'D:\path\excel.xls'
res = pd.DataFrame()
for parent, dirnames, filenames in os.walk(xl_path):
    for filename in filenames:
        df = pd.read_excel(os.path.join(parent, filename))
        df_empty = res.append(df, ignore_index=True)
res.to_excel('D:\path\\new_excel.xls', encoding='utf_8_sig')
