Introduction

Do you want to streamline your Excel process by importing data from a specified table in a different workbook without encountering errors like "Object variable not set (Error 91)"? If so, you’re in the right place! This guide will guide you through the steps to successfully import data from a ListObject table into an array using VBA, while also clearing the contents of the original source table.
