Load xlsx file from drive in colaboratory

问题

How can I import MS-excel(.xlsx) file from google drive into colaboratory?

excel_file = drive.CreateFile({'id':'some id'})

does work(drive is a pydrive.drive.GoogleDrive object). But,

print excel_file.FetchContent()

returns None. And

excel_file.content()

throws:

TypeErrorTraceback (most recent call last) in () ----> 1 excel_file.content()

TypeError: '_io.BytesIO' object is not callable

My intent is (given some valid file 'id') to import it as an io object, which could be read by pandas read_excel(), and finally get a pandas dataframe out of it.

You'll want to use excel_file.GetContentFile to save the file locally. Then, you can use the Pandas read_excel method after you !pip install -q xlrd.

Here's a full example: https://colab.research.google.com/notebook#fileId=1SU176zTQvhflodEzuiacNrzxFQ6fWeWC

What I did in more detail:

I created a new spreadsheet in sheets to be exported as an .xlsx file.

Next, I exported it as an .xlsx file and uploaded again to Drive. The URL is: https://drive.google.com/open?id=1Sv4ib5i7CKWhAHZkKg-uitIkS3xwxtXM

Note the file ID. In my case it's 1Sv4ib5i7CKWhAHZkKg-uitIkS3xwxtXM.

Then, in Colab, I tweaked the Drive download snippet to download the file. The key bits are:

file_id = '1Sv4ib5i7CKWhAHZkKg-uitIkS3xwxtXM'
downloaded = drive.CreateFile({'id': file_id})
downloaded.GetContentFile('exported.xlsx')

Finally, to create a Pandas DataFrame:

!pip install -q xlrd
import pandas as pd
df = pd.read_excel('exported.xlsx')
df

The !pip install... line installs the xlrd library, which is needed to read Excel files.

I'm here to solve this problem.so you can import any file(.csv,.xlsx,...etc)from google drive to google colab.

Solution:

from google.colab import drive
drive.mount('/content/gdrive')

import pandas as pd
df=pd.read_csv('gdrive/My Drive/HDPrice.csv')

df.shape

df

!pip install --upgrade --quiet gspread

from google.colab import auth
auth.authenticate_user()

import gspread
from oauth2client.client import GoogleCredentials
gc=gspread.authorize(GoogleCredentials.get_application_default())

worksheet=gc.open('SampleData').sheet1
cell_list=worksheet

rows=worksheet.get_all_values()
print(rows)

import pandas as pd
pd.DataFrame.from_records(rows)
