Merge a WooCommerce Subscription export with new subscribers into an importer-ready CSV. Everything runs in your browser — no data is uploaded anywhere.
Output uses File B’s columns exactly. Rows match by email (case-insensitive). On a match, non-blank File B values overwrite File A’s; blank File B fields keep File A’s data. The end date always takes File B’s value.
Rows from File B with no matching customer in File A. Import with the WooCommerce Subscriptions Importer (it only creates new subscriptions).
Matched subscribers with their subscription_id, customer_id, email, and merged dates — for WP All Import Pro, matching existing subscriptions on subscription_id.
Embedded previews (like Notion’s) block file downloads. Open this file in a browser tab to download, or use “Show CSV to copy” and paste into a new .csv file.
