Fieldloader: Metafields CSV

Export a metafield, edit it in Excel or Google Sheets, and see the diff before anything is written.

Shopify's product CSV import silently discards variant metafields. Tested on a development store with three header spellings: none of them wrote a value, and every import reported success. With Fieldloader there is nothing to learn: one metafield, one file, a preview of the changes before anything is written, and a rollback to undo an import. Export a row per variant, edit it in Excel or Google Sheets and send the same file back. Extra columns are ignored; bad rows are listed by line number.

• A row for every variant, even with no value, to edit in Excel or Google Sheets
• An emptied cell clears that value; the preview shows it before it happens
• Extra columns are ignored and named in the preview; untitled ones are skipped
• See the diff before anything is written; nothing writes while a row is wrong
• Undo an import with a one-click rollback that puts the old values back
