VBA - working with data videos | How do I get data from multiple workbooks with one query in VBA?
Posted by Andrew Gould on 13 April 2021
One way to get data from closed Excel workbooks is to open each file before extracting the information, but did you know that in VBA you can connect to a workbook and extract data from it without needing to open the file? Even better, if the files you're connecting to have the same structure, you can write a single SQL SELECT statement to select the contents of all the files in one go! This video explains how to do this using the ActiveX Data Objects library. The video shows how to loop through a collection of Excel files in a folder. You'll learn how to create a connection object and build a SQL UNION ALL query to get the data from each closed Excel file. You'll also see how to create a recordset object and load a set of data into it using the SQL statement that you've constructed. As a bonus, the video shows you how to add some basic criteria to the SQL query to control which rows of data you return from the closed workbooks.
This video has the following accompanying files:
| File name | Type | Description |
|---|---|---|
| ADODB Multiple Workbooks One Connection.xlsm | Excel workbook with macros | |
| Movies 2011.xlsx | Excel workbook | |
| Movies 2012.xlsx | Excel workbook | |
| Movies 2013.xlsx | Excel workbook | |
| Movies 2014.xlsx | Excel workbook | |
| Movies 2015.xlsx | Excel workbook | |
| Movies 2016.xlsx | Excel workbook |

Making a video bigger
You can increase the size of your video to make it fill the screen like this:
Play your video (the icons shown won't appear until you do), then click on the full screen icon which appears as shown at its bottom right-hand corner.
When you've finished viewing a video in full screen mode, just press the Esc key to return to normal view.
Improving the quality of a video
To improve the quality of a video, first click on the Settings icon:
Make sure you're playing your video so that the icons shown appear, then click on this gear icon at the bottom right-hand corner.
Choose to change the video quality:
Click on Quality as shown to bring up the submenu.
The higher the number you choose, the better will be your video quality (but the slower the connection speed):
Don't choose the HD option unless you have a fast enough connection speed to support it!
Is your Wise Owl speaking too slowly (or too quickly)? You can also use the Settings menu above to change your playback speed.
