eBay Motors Fitment CSV Build

I need a clean, import-ready CSV that lets my current eBay Motors listings show the right compatibility grid. The products are all aimed at USA-market cars and light trucks, and every line in the file has to carry the full Year / Make / Model / Engine / Trim breakdown so buyers can hit the “Check Fit” button with confidence. You’ll work directly from the titles and descriptions already in my store, matching each SKU to the correct vehicles and populating eBay’s standard columns. When you’re done, I can drop the file into eBay and see green checks—no red errors—so accuracy matters more than speed. Deliverable: • A CSV formatted to eBay Motors’ Parts Compatibility spec, covering every active SKU in my catalogue and listing all applicable Year, Make, Model, Engine, and Trim combinations. If you have solid experience building fitment files for eBay Motors and can cross-reference data quickly in Excel or Google Sheets, let’s get started.
