Bulk editor and CSV import / export (Pro)

Bulk apply

WooCommerce → Bulk Quantity Rules. Choose Apply to products: All products or Products in categories. Tick the Fields to set (only ticked fields are written; everything else is left as it is), optionally Also write the rule onto each variation, and optionally Replace tiers with one tier per line as from,to,mode,value (e.g. 10,49,percent,10). Click Apply a rule: products are processed in batches with a progress bar, so thousands of products are fine.

Export

Export CSV downloads every product and variation with its current rule and tiers:

product_id, sku, name, enabled, min, max, step, default, input_mode, fixed_values, decimal, unit_label, tiers_json

Import

Edit the exported file in a spreadsheet and upload it back. Rules:

• product_id must exist: rows with an unknown ID are skipped, the rest still import.
• enabled: no disables the product rule; anything else keeps it enabled.
• input_mode is input or fixed; fixed_values is comma-separated (12,24,48).
• decimal is yes / no.
• tiers_json is a JSON array: [{"min":10,"max":49,"mode":"percent","value":10},{"min":50,"max":"","mode":"fixed","value":7.5}]. Leave the cell empty to keep existing tiers.
• Only product_id is required; missing columns are written as blank (“inherit”), so export first and edit the file rather than building one from scratch.
