Update Fan Inventory Excel File

I have an existing fan inventory maintained in a single Excel/CSV file. Every line already lists the basic item, but several key columns are blank or outdated. I need those gaps filled with the correct product details, current unit price, and the supplier name for each fan model.

You will work directly in the original sheet so the layout, formulas, and any hidden metadata stay intact. Once you finish, simply return the same file—just updated and error-free—so I can slot it straight back into our workflow without re-formatting.

Accuracy is paramount; mismatched model numbers or stray characters will throw off our reorder triggers. If a data point is genuinely missing, flag it clearly rather than guessing. I’m happy to answer quick questions or supply reference documents if you hit a dead end with a particular SKU.

The ideal outcome is an updated version of the original file with every row complete, consistent, and ready for immediate use.
