I expect to get a working solution for the following problem: list and read all.gsheet files in a given directory of a Google Drive mounted in Google Colab.

I am working on a Google Colab notebook that requires the user to mount google drive using the colab.drive python library. They then input relative paths on the local directory tree ( /content/drive/... by default on that mount) to files of interest for analysis. Now, I want to use a Google Sheet they can create as a configuration file. There is lots of info on how to authenticate gspread and fetch a sheet from its HTTPS url , but I can't find any info on how to access the .gsheet file using gspread that is already mounted on the local filesystem of the colab runtime.

There are many tutorials using this flow: https://colab.research.google.com/notebooks/io.ipynb#scrollTo=yjrZQUrt6kKj , but I don't want to make the user authenticate twice (having already done so for the initial mount), and i don't want to make them input some files as relative path, some as HTTPS URL.

I had thought this would be quite like using gspread to work with google sheets that I might have on my locally mounted drive as well. But, I haven't seen this workflow anywhere either. Any pointers in that direction might help me out as well.

Thank you!

Yes, we can import data from Google Sheets too, using the existing open-source gspread library for interacting with Sheets. But First, we need to install the package using pip.

!pip install — upgrade -q gspread

Next, we'll import the library, authenticate, and create the interface to sheets.

from google.colab import auth
auth.authenticate_user()
import gspread
from oauth2client.client import GoogleCredentials
gc = gspread.authorize(GoogleCredentials.get_application_default())

After executing this code, you will find a input box same as we saw while getting permission for google drive. Visit link and login in your google account and copy and paste the verification code in this box.

Now, you can upload as well as download data to and from google sheets. To read data from google sheet execute the following code.

# Open your exisiting sheet and read some data.
worksheet = gc.open(‘spreadsheet name’).sheet1
# get_all_values gives a list of rows.
rows = worksheet.get_all_values()
print(rows)
# Convert to a DataFrame and render.
import pandas as pd
pd.DataFrame.from_records(rows)

Instead of adding .gsheet on colab's drive you can try storing it in the user's drive and later fetch from there when needed. So until that kernel is running you won't have to re-authenticate the user.

I'm also not finding anything to authenticate into colab from other device. So you would consider modifying your flow a bit.
