You can easily make changes to your product CSV using a spreadsheet software like Google Sheets. Export your products, edit the tag columns, then import the new file. New to working with CSV files? Find detailed instructions here.

Hi @Soysauce1 ,
You can easily bulk edit your Shopify product tags using Mixtable's Excel-like spreadsheet interface for Shopify. Sync your product data to a worksheet, map the product tags to a column, edit the tags in bulk by using an Excel formula or through copying/pasting the contents of cells, and then sync the changes back to Shopify by saving your workbook.
