Hello, I carefully reviewed your project and understand that you need a clean, reliable, and fully working Excel (Mac) Power Query solution to compare supplier price lists and identify the cheapest supplier per product. I also noted that previous attempts failed due to over-complicated approaches. My focus will be to build a simple, robust, and easy-to-maintain solution that works consistently. My approach: • Import multiple supplier files dynamically using Power Query • Standardize and detect EAN/UPC fields across different file structures • Normalize price formats (EU 12,50 and US 12.50) into a consistent numeric format • Match products across suppliers using EAN/UPC as the key • Build a comparison table showing all supplier prices side-by-side • Calculate Best Price and automatically identify the Cheapest Supplier • Include product details (Description, Brand, Format) where available I will keep the model clean, well-structured, and fully test it to ensure it runs smoothly on Excel for Mac without unnecessary complexity. I can also provide clear instructions so you can easily update or add new supplier files in the future. I am confident I can deliver a stable and working solution within your timeline.

Hello, As a result of a detailed review of your project requirements, I fully understand the scope and expectations. I have experience building clean Excel and Power Query tools, and I’m available to start right now. I bring strong expertise in Excel for Mac, Power Query, Data Integration, Data Processing, Data Analysis, and Data Management with over 10 years of experience. One key challenge here is keeping the solution simple and reliable: importing multiple supplier files, detecting EAN/UPC columns, normalizing EU/US price formats, matching products correctly, and generating a clear comparison table with Best Price and Cheapest Supplier. I would build this as a tested Power Query workflow with easy folder-based import, clear column mapping, and refresh instructions so you can update supplier files without rebuilding anything. I have a couple of quick questions. • Do all supplier files have similar column names, or should the tool handle different headers? • Should the final output show all supplier prices side by side or only the cheapest result? Best regards, Carlos.

Hi there!

I also specialize in handling mixed data formats like EU/US pricing, ensuring accurate calculations and matching across datasets. My approach will be to build a simple and stable Power Query workflow that reads all supplier files automatically. I will normalize EAN/UPC matching and clean price formats into a consistent structure. I will design a clear comparison table that shows best price and cheapest supplier per product. I will ensure the solution is lightweight, fully working on Mac Excel, and easy for you to update with new supplier files. check our work https://www.freelancer.com/u/ayesha86664 Do all your supplier files follow the same column names, or do they vary between vendors?
