Four realistic methods — from free-but-manual to fast-but-assisted — and when each one makes sense.
Editing product descriptions one by one is the slowest job in ecommerce. If you have more than a few dozen products, you need a bulk workflow. Here are the four realistic ways to do it in Shopify, from free-but-manual to fast-but-assisted — and when each one makes sense.
Shopify’s bulk editor (Products → select items → Edit products) lets you add columns and edit fields across many products in a table. It is free and built in, but the description column is awkward for long, formatted text, and there is no way to generate copy — you still write every word yourself. Good for small tweaks, not for rewriting a catalog.
Export your products (Products → Export), open the CSV in Google Sheets or Excel, edit the Body (HTML) column, then re-import. It works for bulk changes and is free, but the descriptions contain raw HTML, big catalogs make unwieldy files, and a bad import can overwrite the wrong fields. Export only the columns you need and test on a few products first.
Apps like Matrixify give you filtered exports, safer imports, and scheduling — a big step up from raw CSVs for large stores. You still write the copy yourself; the app just moves it in and out efficiently. Best when you have a lot of products and want control over exactly which fields change.
The bottleneck usually isn’t moving text — it’s writing hundreds of unique, on-brand descriptions. An AI tool generates them in bulk so you spend your time reviewing and editing instead of starting from a blank box. The important part is that the output stays in your brand voice and stays unique per product, and that you review before it saves.
OnBrand AI writes unique descriptions, SEO titles & meta, and alt text across your whole catalog in your brand voice — you review Before vs. After and publish only what you approve.
Get OnBrand AI on the Shopify App Store →Yes — the built-in bulk editor and CSV export/import are both free. They move and edit text well, but neither writes descriptions for you; you still author every word.
Generating them with an AI app and reviewing the output is far faster than writing each by hand, as long as the copy stays unique and on-brand. Keep a human review step before publishing.
Not if the content stays unique and relevant. The risk is pasting the same text across many products — that creates duplicate content. Keep each description distinct.
