I run an established retail site that I still maintain in Adobe Dreamweaver. Each month I receive an updated price sheet and currently change every product page by hand. I’d like to replace that routine with an AI-driven workflow that ingests my spreadsheet, checks the existing catalog, and applies the new prices automatically. Here’s what I need: • A seamless module or script—Python, PHP, or JavaScript are all acceptable—that plugs into my current Dreamweaver project without forcing a complete rebuild. • On upload of my monthly file (CSV or XLSX), the system should map the SKU or product ID, detect differences, and update the relevant price fields in the site’s HTML / database. • Basic “sanity checks”: flag any SKU mismatches, price drops or increases beyond a set percentage, and create a short summary report before final write-back. • A simple on-page or dashboard prompt where I can review, approve, or roll back the AI’s proposed changes. • Clear documentation so I can repeat the process each month and, if needed, extend it later to pull in competitor pricing or market-trend APIs. Acceptance criteria 1. I trigger an upload, the AI parses the file, and within one session I see every product that will change. 2. After approval, the updated prices appear live on the site without breaking layout or links. 3. The summary report logs the number of items processed and any anomalies. If you can deliver clean code, easy deployment, and a quick walkthrough, I’m ready to get started right away.
