The Scenario
The theme migration is scheduled for next month and the developer handling it has one question: what custom metafields do we currently have, and are any of them orphaned? You have 400 products. The developer needs every metafield — namespace, key, type, value — in a Google Sheet so he can map what carries over and what gets dropped.
Nobody on the team has done a metafield audit before. Nobody knows where to start in the admin.
The bad version:
- Open Shopify's admin, navigate to a product, scroll to Metafields, note the values.
- Repeat for each of the 400 products. Some products have 3 metafields. Some have 12.
- Export your notes into a sheet, realize the structure is inconsistent because you didn't decide on a column format before you started, and do it again.
The developer is waiting. The migration has a deadline. This audit needs to exist before either of those conversations can move forward.
The Easy Way: One Prompt in SheetXAI
SheetXAI is an AI agent that lives inside your Google Sheet. It reads every product's metafields from Shopify and writes them into the sheet — one row per metafield, structured consistently across all 400 products, in one operation.
Fetch all metafields for every product in my Shopify store and write product ID, product title, namespace, key, type, and value into my Metafield Audit sheet — one row per metafield
What You Get
- One row per metafield across all 400 products, with product ID, product title, namespace, key, type, and value in clearly labeled columns.
- A complete picture of every namespace in use, making it easy to sort by namespace and identify which ones are system-generated versus custom.
- Empty value cells visible immediately — no hunting for orphaned metafields by hand.
What If the Data Is Not Quite Ready
You only need metafields in a specific namespace
Fetch all product metafields from my Shopify store where namespace is 'custom' and write product ID, product title, key, type, and value into my Metafield Audit sheet — one row per metafield
You want to flag rows where the value is empty
Fetch all product metafields from my Shopify store and write product ID, product title, namespace, key, type, and value into my Metafield Audit sheet — add a column G that says 'empty' if value is blank and 'ok' otherwise
Metafields across products and variants both need auditing
Fetch all metafields for every product and every product variant in my Shopify store and write resource type, resource ID, resource title, namespace, key, type, and value into my Full Metafield Audit sheet — one row per metafield
Full audit: all namespaces, all resources, flag empties, group by namespace
Fetch all product and variant metafields from my Shopify store and write into my Metafield Audit sheet — include resource type, resource ID, title, namespace, key, type, value — add a column flagging empty values — sort the output by namespace then key
Running the complete audit in one prompt means the developer gets a single sheet with everything needed, not a partial export you have to supplement.
Try It
Get the 7-day free trial of SheetXAI and open a blank Google Sheet before your next theme migration kickoff, then ask SheetXAI to pull the full metafield audit. Your developer gets a structured reference and you avoid two days of manual product-by-product review.
