Linking BaseLinker and WooCommerce products with CSV

CSV can carry a mapping, but the file does not understand products or variants. First identify the destination and its supported import mechanism.

Build the identifier map

Connect source ID, destination ID, SKU and variant-parent relationship. Names are supporting information only. Ambiguous matches do not reach the write stage.

Match the recipient schema

Use the selected importer's columns and format. WooCommerce documents its own product and variant schema; this does not automatically create a BaseLinker association. Verify that connection separately.

Documentation: WooCommerce — Product CSV Importer and Exporter.

Preserve values

Check encoding, separators, empty fields and leading zeros. A spreadsheet must not turn an identifier into a number or date. Read the file back before import.

Try a small sample

On a copy, test a simple product, variants, duplicates and missing IDs. Keep the original export and change report. An update must not create a second product.

Verify the association

Read both ends and the correct variant. Then verify stock and price synchronisation rules. Successful CSV parsing does not prove correct mapping.
