Write Product Descriptions for FTP CSV Supplier Feeds with Claude

3 min setup

No coding required

Runs automatically

Supplier feeds on FTP usually arrive with a SKU, a terse title, and a line of specs, which is nowhere near ready for a product page. This workflow watches a CSV file on your FTP server, and for every new row it has Claude turn the supplier's raw fields into a clear, customer-friendly product description. The finished copy is written back to a CSV on the same FTP server, matched by SKU, ready to import into your store.

3 steps to turn raw FTP supplier CSV rows into ready-to-use product descriptions with Claude

App connector: FTP • Time to complete: 1 minute

Check the supplier's CSV file on the FTP server on a recurring interval and run once for each new row. Each row provides columns such as SKU, supplier title, specs, materials, and dimensions.

App connector: Claude • Time to complete: 1 minute

Send Claude the row's supplier title, specs, materials, and dimensions. Ask for a product title under 70 characters and a description of 80 to 120 words that leads with the main benefit, lists key specs as short bullet points, and uses only facts from the row. Return the title and description as separate fields.

App connector: FTP • Time to complete: 1 minute

Write the SKU, Claude's title, and Claude's description to an output CSV on the FTP server, updating the existing row when the SKU is already there so reruns never create duplicates.

FAQs

Will Claude make up product details that are not in the feed?

The prompt tells Claude to use only facts from the CSV row. It is still worth spot-checking the first batch, especially for sizing, materials, and care instructions.

Why write the descriptions to a CSV instead of straight to my store?

A CSV keeps the workflow to just these two apps and gives you a file you can review and bulk import. You can also add a step that updates the matching product in your store by SKU instead.

What happens if the supplier re-uploads the same file?

The trigger only runs for rows it has not seen before, and the final step updates rows by SKU, so repeated uploads do not create duplicate descriptions.

Customize this workflow even further:

Match your brand voice

Paste two or three of your best existing product descriptions into the Claude prompt as examples so new copy sounds like the rest of your catalog.

Add SEO fields

Ask Claude for a meta title and meta description too, and add them as extra columns in the output CSV.
