Shopify Data Scraping and Excel Consolidation

I need data scraped from a Shopify website and consolidated into an Excel spreadsheet. The data includes:

Product details: name, description, price
Inventory and stock levels

Additionally, I have two existing spreadsheets that need to be combined without duplicating data. The primary key for identifying duplicates will be the product name & SKU number

Requirements:
- Scrape specified data from Shopify site
- Consolidate into Excel using original spreadsheets layout.
- Merge two existing spreadsheets, ensuring no duplicates using SKU as key

Ideal Skills:
- Experience with web scraping tools and techniques
- Proficiency in Excel, especially in data consolidation and handling duplicates
- Attention to detail to ensure data accuracy and integrity

Please provide relevant experience in your bid.
