Amazon & Flipkart Data Automation

I currently copy price, review count, star rating and the ASIN or FSN for each of my catalogue items from Amazon.in and Flipkart.com into one Google Sheet every single day. I now want that entire routine converted into code.

Here’s what I need built:

• A web-scraping script (Python, Node or similar—happy to hear your suggestion) that reads a list of product URLs or IDs, grabs the current selling price, total reviews, average rating and the same ASIN/FSN, then writes everything to a single master Google Sheet.
• A date-stamped row for every product so historical pricing and rating trends are preserved.
• Automatic execution once every 24 hours at a fixed time I can edit later; a simple cron job, Cloud Function or Apps Script trigger is fine.
• Basic resilience against common blocks on Amazon and Flipkart—user-agent rotation or headless browser fallback is acceptable, nothing too exotic.
• Clear setup instructions plus well-commented source so I can add or remove products without touching the code.

Acceptance criteria
1. Running the scheduled job populates a fresh row for each listed product in the Google Sheet with correct marketplace, ASIN/FSN, price, total reviews, rating and timestamp.
2. No manual intervention is required after initial deployment.
3. Full source code and a short read-me are delivered.

If this sounds like your wheelhouse, let’s get it live.
