Question

How to extract photos from Google Sheets cells using the gspread library?

I’m developing a script to parse data from Google Sheets, where each row contains information about 5 products (name, price, quantity, etc.). However, I’ve encountered a problem with extracting photos from a specific column. I couldn’t find suitable documentation or code examples for this task. Some sources claim that obtaining images through the Google Sheets API directly is impossible. Could you please advise if there’s a way to extract photos from cells using gspread or alternative methods to solve this issue?

Unfortunately, the gspread library does not support direct extraction of images from Google Sheets cells. The main reason is that gspread is designed to work with text data and cell values, not with media files stored in Google Sheets. However, there are alternative methods to solve this problem, mainly through the Google Drive API or using the IMAGE formula with subsequent URL processing.

Direct Image Extraction through gspread

The gspread library, despite its power for working with Google Sheets, does not provide built-in functions for extracting images from cells. As stated in the official documentation and confirmed in GitHub discussions, gspread primarily focuses on working with text data, cell formatting, and basic spreadsheet operations.

From research sources, it’s evident that when attempting to retrieve data from cells with images through get_all_values() or range(), you will only get text values, not the actual images. This is because images in Google Sheets are technically not cell content, but rather separate objects overlaid on cells.

It’s important to understand: Images in Google Sheets are not stored as cell values, but are separate graphical objects, which makes their extraction through standard gspread methods impossible.

Alternative Image Extraction Methods

Since direct image extraction through gspread is impossible, there are several alternative approaches to solving this task:

1. Using the IMAGE Formula

If images in your spreadsheet were added using the IMAGE() formula, then gspread will be able to extract the image URLs. In this case, each cell will contain not the image itself, but its URL:

python
import gspread
from oauth2client.service_account import ServiceAccountCredentials

# Authentication
scope = ['https://spreadsheets.google.com/feeds', 'https://www.googleapis.com/auth/drive']
credentials = ServiceAccountCredentials.from_json_keyfile_name('credentials.json', scope)
client = gspread.authorize(credentials)

# Opening the spreadsheet
sheet = client.open('Your Sheet Name').sheet1

# Getting image URLs
images_urls = sheet.col_values(5)  # Assuming URLs are in the 5th column

2. Saving Images to Google Drive

If images were inserted directly into cells, they are actually stored in Google Drive. You can use the following approach:

  1. Find image IDs in cells (this is possible through advanced use of Google Sheets API)
  2. Use Google Drive API to download images by their IDs

Solution through Google Drive API

The most reliable solution is to use a combination of Google Sheets API and Google Drive API:

python
import gspread
from googleapiclient.discovery import build
import requests
import os

# Authentication
scope = ['https://spreadsheets.google.com/feeds', 'https://www.googleapis.com/auth/drive']
credentials = ServiceAccountCredentials.from_json_keyfile_name('credentials.json', scope)
client = gspread.authorize(credentials)

# Creating services
sheets_service = build('sheets', 'v4', credentials=credentials)
drive_service = build('drive', 'v3', credentials=credentials)

def extract_images_from_sheet(sheet_url, column_letter):
    """
    Extract images from a specified column in Google Sheets
    """
    # Get spreadsheet ID from URL
    spreadsheet_id = sheet_url.split('/d/')[1].split('/')[0]
    
    # Get data from column
    range_name = f'{column_letter}1:{column_letter}'
    result = sheets_service.spreadsheets().values().get(
        spreadsheetId=spreadsheet_id,
        range=range_name
    ).execute()
    
    values = result.get('values', [])
    
    # For each cell with an image
    for row_idx, row in enumerate(values, start=1):
        if row and 'IMAGE(' in row[0]:
            # Extract image ID from URL
            image_url = row[0]
            image_id = image_url.split('id=')[1].split('&')[0]
            
            # Download image via Drive API
            request = drive_service.files().get_media(fileId=image_id)
            image_data = request.execute()
            
            # Save image
            filename = f'image_{row_idx}.jpg'
            with open(filename, 'wb') as f:
                f.write(image_data)
            
            print(f'Image saved: {filename}')

Code Examples for Working with Images

Here’s a practical example that you can adapt for your task:

python
import gspread
from oauth2client.service_account import ServiceAccountCredentials
import urllib.request
import os

def setup_gspread():
    """Setup connection to Google Sheets"""
    scope = ['https://spreadsheets.google.com/feeds', 'https://www.googleapis.com/auth/drive']
    credentials = ServiceAccountCredentials.from_json_keyfile_name('credentials.json', scope)
    return gspread.authorize(credentials)

def extract_product_data(sheet_name, image_column='E'):
    """
    Extract product data including images
    """
    client = setup_gspread()
    sheet = client.open(sheet_name).sheet1
    
    # Get all data from the spreadsheet
    all_data = sheet.get_all_values()
    
    products = []
    
    for row in all_data[1:]:  # Skip headers
        if len(row) >= 5:  # Make sure all columns exist
            product = {
                'name': row[0],
                'price': row[1],
                'quantity': row[2],
                'description': row[3],
                'image_url': row[4] if row[4] else None
            }
            
            # If there's an image URL, download it
            if product['image_url'] and 'IMAGE(' in product['image_url']:
                try:
                    image_url = extract_image_url(product['image_url'])
                    if image_url:
                        product['image_data'] = download_image(image_url)
                        product['image_filename'] = f"product_{len(products)}.jpg"
                except Exception as e:
                    print(f"Error downloading image: {e}")
            
            products.append(product)
    
    return products

def extract_image_url(image_formula):
    """Extract real URL from IMAGE formula"""
    # Example: =IMAGE("https://drive.google.com/uc?export=view&id=1ABC123XYZ")
    start = image_formula.find('"') + 1
    end = image_formula.rfind('"')
    return image_formula[start:end]

def download_image(url, save_path='images'):
    """Download image from URL"""
    if not os.path.exists(save_path):
        os.makedirs(save_path)
    
    filename = os.path.join(save_path, url.split('/')[-1])
    urllib.request.urlretrieve(url, filename)
    return filename

# Example usage
products_data = extract_product_data('Your_Sheet_Name')
for product in products_data:
    print(f"Product: {product['name']}")
    if 'image_filename' in product:
        print(f"  Image saved: {product['image_filename']}")

Limitations and Recommendations

Main Limitations:

  1. Lack of direct support: gspread is not designed to work with media files
  2. Authentication requirements: Working with Drive API requires extended permissions
  3. Processing complexity: Image extraction requires additional processing steps

Recommendations:

  1. Use structured URLs: If possible, save image URLs directly in cells without formulas
  2. Optimize storage: Store images in Google Drive and reference them through cells
  3. Consider alternative libraries: For complex image tasks, you may need to use Google APIs directly

Alternative Approaches:

  1. Google Apps Script: Create a script in the spreadsheet to process images
  2. Google Data Studio: For visualizing data with images
  3. Custom function: Create your own function in Google Sheets for image extraction

Conclusion

Extracting photos from Google Sheets cells using gspread is not a trivial task, but it’s possible with the right approach:

  1. Main problem: gspread doesn’t support direct image extraction since images are not cell values
  2. Solution: Use a combination of Google Sheets API and Google Drive API to work with images
  3. Practical approach: Extract image URLs from cells, then download them via Drive API
  4. Alternatives: Consider using the IMAGE formula or storing images in Google Drive with references in the spreadsheet

For your product data parsing script, it’s recommended to create a separate function for image processing that uses the methods described. Note that this process requires additional permission settings and may take more time to implement compared to regular text data extraction.
