No one wants to manually go through every listing and replace text.
If you have the same wording in all your listings that you need to replace, you can easily find and replace the wording.
Pull up your listings in the bulk editor.
Click on the Edit button and select “Item description”.
When the box pops up, click the dropdown and select “Edit listings in bulk – find and replace”.
In the “Find” box, type the wording you want to change.
In the “Replace” box, type the new wording. If you want to remove wording and replace it with nothing, put two spaces in the box.
