VBA - working with data videos | How do I loop through worksheets in a closed workbook with VBA?

Posted by Andrew Gould on 09 April 2021

Looping through the collection of worksheets in a workbook is a standard technique in Excel VBA and easy to accomplish when the workbook is open. Did you know that you can do the same thing when the workbook is closed? This video explains how to do this using the ActiveX Data Objects library. You'll learn how to create a connection object and construct a connection string to talk to the closed Excel file. You'll learn how to query the schema of the workbook to return a list of the worksheets and loop through this list to read the name of each sheet. You'll also learn how to create a recordset object and populate it with data using an SQL Select statement. As a bonus you'll learn about the SQL Union All statement to select data from multiple tables at the same time and how to add criteria to a query using the Where clause.
