python – add hyperlink to excel sheet created by pandas dataframe to_excel method

Posted by: admin March 9, 2020 Leave a comment

Questions:

I have converted a pandas DataFrame to an Excel sheet using df.to_excel.

Now, I want to add hyperlinks to the values in one column. In other words, when a customer sees my excel sheet, he would be able to click on a cell and bring up a webpage (depending on the value in this cell).

How to&Answers:

You could use the HYPERLINK function

import pandas as pd
df = pd.DataFrame({'link':['=HYPERLINK("http://www.someurl.com", "some website")']})
df.to_excel('test.xlsx')

Answer:

Building on the approach by @guillaume-jacquenot we can use apply to apply this to an entire Series.

df = pd.DataFrame({'Year': [2000, 2001, 2002 , 2003]})

For cleanliness, I wrote a helper method.

def make_hyperlink(value):
    url = "https://custom.url/{}"
    return '=HYPERLINK("%s", "%s")' % (url.format(value), value)

Then, apply it to the Series:

df['hyperlink'] = df['Year'].apply(lambda x: make_hyperlink(x))

    Year    hyperlink
0   2000    =HYPERLINK("https://custom.url/2000", "2000")
1   2001    =HYPERLINK("https://custom.url/2001", "2001")
2   2002    =HYPERLINK("https://custom.url/2002", "2002")
3   2003    =HYPERLINK("https://custom.url/2003", "2003")

Answer:

From @maxymoo’s answer, here is a full example

import pandas as pd
df = pd.DataFrame({'Year': [2000, 2001, 2002 , 2003]})
df['link'] = '-'
df.set_value(0, 'link', '=HYPERLINK("https://en.wikipedia.org/wiki/2000", 2000)')
df.set_value(1, 'link', '=HYPERLINK("https://en.wikipedia.org/wiki/2001", 2001)')
df.set_value(2, 'link', '=HYPERLINK("https://en.wikipedia.org/wiki/2002", 2002)')
df.set_value(3, 'link', '=HYPERLINK("https://en.wikipedia.org/wiki/2003", 2003)')
df.to_excel('test.xlsx', index = False)

Answer:

You can use:

df = pd.DataFrame(list(range(5)), columns=['a'])

df['a'] = df['a'].apply(lambda x: '<a href="http://youtube.com/{0}">link</a>'.format(x))

HTML(df.to_html(escape=False))

Answer:

I was generating text files from a excel file and wanted to link the names of the generated .txt files to a particular existing column in the Dataframe.

I was trying to push the local drive directory where the generated .txt files are stored, to the corresponding “File Name”. So that on clicking the file name, it will open the .txt file.

The dataframe

rancheck_DF = pd.read_excel(excel_file, delim_whitespace = True, encoding = 'utf-8')

for index_df in range(len(rancheck_DF)):

    Desc = rancheck_DF.loc[index_df,'Description Text']

    MainFile = rancheck_DF.loc[index_df,'File Name']

    fileName = r'.\Documents\TestF\TestF_{}.txt'.format(index_df)

    with open(fileName, 'w', encoding='utf-8') as txtfile:
        txtfile.write(Desc)

    rancheck_DF.loc[index_df,'File Name'] = '=HYPERLINK("{}","{}")'.format(fileName,MainFile)

rancheck_DF.to_excel('./damn.xlsx', index=None)
