Pandas read_excel with Hyperlink

我有一个Excel电子表格,我正在阅读Pandas DataFrame:

df = pd.read_excel("file.xls")

但是,电子表格的其中一列包含具有与其相关联的超链接的文本。如何在Pandas中访问底层超链接?

这可以用openpyxl完成,我不确定它是否可以用Pandas。我是这么做的:

import openpyxl

wb = openpyxl.load_workbook('yourfile.xlsm')
sheets = wb.sheetnames
ws = wb[sheets[0]]
# Deprecation warning
# ws = wb.get_sheet_by_name('Sheet1')
print(ws.cell(row=2, column=1).hyperlink.target)

你也可以使用iPython,并设置一个变量等于超链接对象:
t = ws.cell(row=2, column=1).hyperlink
然后做t.和按tab键,以查看所有的选项,你可以做什么或访问从该对象.

快速猴子修补,没有转换器或类似的东西,如果你想把所有的单元格与超链接作为超链接,更复杂的方式,我想,至少能够选择,哪些列视为超链接或收集数据,或以某种方式保存数据和超链接在同一个单元格在dataframe。使用转换器,不知道。(顺便说一句,我也玩过data_onlykeep_links,没有帮助,只有改变read_only结果确定,我想它可以减慢你的代码速度)。
P.S.:仅适用于xlsx,即引擎是openpyxl
P.P.S.:如果你在未来阅读这篇评论并发布https://github.com/pandas-dev/pandas/issues/13439仍然打开,不要忘记在pandas.io.excel._openpyxl上查看_convert_cellload_workbook的更改并相应地更新它们。

import pandas
from pandas.io.excel._openpyxl import OpenpyxlReader
import numpy as np
from pandas._typing import FilePathOrBuffer, Scalar

def _convert_cell(self, cell, convert_float: bool) -> Scalar:
    from openpyxl.cell.cell import TYPE_BOOL, TYPE_ERROR, TYPE_NUMERIC
    # here we adding this hyperlink support:
    if cell.hyperlink and cell.hyperlink.target:
        return cell.hyperlink.target
        # just for example, you able to return both value and hyperlink,
        # comment return above and uncomment return below
        # btw this may hurt you on parsing values, if symbols "|||" in value or hyperlink.
        # return f'{cell.value}|||{cell.hyperlink.target}'
    # here starts original code, except for "if" became "elif"
    elif cell.is_date:
        return cell.value
    elif cell.data_type == TYPE_ERROR:
        return np.nan
    elif cell.data_type == TYPE_BOOL:
        return bool(cell.value)
    elif cell.value is None:
        return ""  # compat with xlrd
    elif cell.data_type == TYPE_NUMERIC:
        # GH5394
        if convert_float:
            val = int(cell.value)
            if val == cell.value:
                return val
        else:
            return float(cell.value)

    return cell.value

def load_workbook(self, filepath_or_buffer: FilePathOrBuffer):
    from openpyxl import load_workbook
    # had to change read_only to False:
    return load_workbook(
        filepath_or_buffer, read_only=False, data_only=True, keep_links=False
    )

OpenpyxlReader._convert_cell = _convert_cell
OpenpyxlReader.load_workbook = load_workbook

在python文件中添加了上面的代码后,您将能够调用df = pandas.read_excel(input_file)
在写了这些东西之后,我突然想到,也许使用openpyxl本身会更简单,更干净^_^

正如slaw评论的那样,它不抓取超链接,而只抓取文本
这里text.xlsx在第9列中包含链接

from openpyxl import load_workbook
workbook = load_workbook('test.xlsx')
worksheet = workbook.active

column_indices = [9]

for row in range(2, worksheet.max_row + 1):
    for col in column_indices:
        filelocation = worksheet.cell(column=col, row=row)  # this is hyperlink
        text = worksheet.cell(column=col + 1, row=row)  # thi is your text 
        worksheet.cell(column=col + 1, row=row).value = '=HYPERLINK("' + filelocation.value + '","' + text.value + '")'

workbook.save('test.xlsx')

你不能在Pandas身上这样做。你可以试试other libraries designed to deal with excel files
