How to Download a Specific Revision of a Google Slides File

What will you learn?

In this tutorial, you will master the art of downloading a specific revision of a Google Slides file using Python. Dive into the realm of Google Drive API and harness its power to access and retrieve precise versions of your collaborative presentations.

Introduction to the Problem and Solution

Collaborative documents like Google Slides often undergo multiple revisions, creating a trail of changes over time. At times, there arises a need to retrieve an older version for reference or comparison purposes. The solution lies in tapping into the capabilities of the Google Drive API through Python. By seamlessly navigating through specific revisions, you can effortlessly download the desired iteration of your Google Slides file.


# Import necessary libraries
from googleapiclient.discovery import build

# Set up credentials and create the Drive service
# Visit for detailed instructions on setting up authentication

# Specify the file ID of the Google Slides presentation
file_id = 'YOUR_FILE_ID'

# Specify the revision ID of the specific version you want to download

drive_service = build('drive', 'v3')
request = drive_service.revisions().get_media(fileId=file_id, revisionId=revision_id)

fh = open('downloaded_presentation.pptx', 'wb')
downloader = MediaIoBaseDownload(fh, request)
done = False

while done is False:
    status, done = downloader.next_chunk()

To embark on downloading a particular revision of your Google Slides file, begin by authenticating your application with OAuth 2.0 permissions. Utilize the googleapiclient library to interface with the Drive API efficiently. By pinpointing both the file ID and revision ID, you can seamlessly retrieve that specific version from Google Drive.

The code orchestrates an authenticated connection with the Drive service, fetches media content for the designated revision, and saves it locally as a PowerPoint presentation (‘downloaded_presentation.pptx’). The utilization of MediaIoBaseDownload class ensures streamlined management during large file downloads.

  1. How do I obtain my Google Slides file ID?

  2. Your file ID can be found within the URL while viewing your document on Google Drive.

  3. Where do I get my revision ID?

  4. Revision IDs are distinctive identifiers assigned by Google Drive for each version; they can be acquired programmatically via API calls or manually extracted from metadata.

  5. Can I specify which format I want to download in?

  6. Certainly! You have the flexibility to opt for various export formats supported by Google Slides like PDF or PPTX based on your preferences.

  7. Is there any limit on how many revisions back we can go?

  8. Google Drive retains all revisions but stores them up to 100 versions per document; beyond this threshold, older versions are automatically purged.

  9. How secure is it to authenticate via OAuth 2.0?

  10. OAuth 2.0 guarantees secure authorization by offering restricted access scopes without exposing user credentials directly during authentication processes.


In conclusion, delving into downloading specific revisions from cloud services such as Google Drive unveils seamless possibilities through Python libraries and APIs like googleapiclient. This not only streamlines historical data management but also paves way for automated backup strategies tailored to diverse user requirements across education sectors seeking academic record archiving flexibility or corporate entities mandating compliance-oriented data retention policies adherence. Embrace this tech-driven approach backed by Python ecosystems transforming conventional workflows into dynamic efficiency engines poised towards future-ready digital transformations shaping tomorrow’s information landscapes today.
