Automate weekly store updates from a spreadsheet

A custom agent keeps an online shop current by reading a weekly inventory sheet, revising listings, and asking for approval on unclear items.

What they did
The owner set up a dedicated email address that receives a weekly inventory spreadsheet. The agent reads that sheet, changes each product’s price and stock, removes items that no longer appear, and checks the maker’s page for new products so it can write a fresh listing with a description, search title, image text, and struck-through original price. It also turns rough product photos into clean studio-style images and stops when something seems uncertain.
How it went
After that, the owner only has to send one email each week, and the agent handles the rest of the shop. Any unclear item is held back until a person approves it.
Tips
Use a clear approval step for anything uncertain, especially before publishing or deleting products. A spreadsheet-driven setup works best when your source data is consistent and your product pages are easy to verify.

Each week, when I send a new inventory file to [email address] or add it to [folder/spreadsheet link], update my store on [platform] with the latest prices and stock counts. For each new item, look up the maker page, write an original listing with a short description, search-friendly title, image text, and crossed-out original price in [tone]. If a product is missing from the sheet, remove it only after showing me a summary and getting my approval. If any detail is unclear, hold that item, send me the flagged list at [email], and wait for my confirmation before publishing, deleting, or sending anything live. When the clear items are finished and the flagged items are paused, stop and report completion.

Fill in the [brackets]. Agents can make mistakes, so review anything before it is sent, paid or deleted.
