Using a Single Instance of Excel with Two Monitors

by Allen Wyatt
(last updated August 15, 2018)


Joe has a system that uses dual monitors. He would like to have one Excel workbook appear on one of the monitors and another workbook appear on the other monitor. He can do this, but only if he opens two instances of Excel. The problem with that, however, is that he cannot easily copy and paste information from one workbook to another. What would be ideal is if Joe could open both workbooks in a single instance of Excel and still have the two workbooks appear on their own monitors.

Assuming that you've got Windows configured so that it views the two monitors as a single desktop, there is only one way to do this that we've been able to discover. Follow these general steps:

  1. Open one of the workbooks in Excel, as you normally would.
  2. Make sure that the Excel program window doesn't fill the entirety of a monitor. (Click the Restore button, in the upper-right corner of the program window, if necessary.)
  3. Make sure the program window is fully visible in your left-most monitor. (Drag the title bar of that program window into that monitor, if necessary.)
  4. Drag the right side of the program window into the right-most monitor. Your program window should now cover most of the extended desktop, across two monitors.
  5. Open the second workbook in this same instance of Excel.
  6. Display the View tab of the ribbon.
  7. Click the Arrange All tool in the Window group. You should see the Arrange Windows dialog box. (See Figure 1.)
  8. Figure 1. The Arrange Windows dialog box.

  9. Make sure the Vertical radio button is selected.
  10. Click OK.
  11. Drag the borders of the workbooks so that each appears fully in the left and right monitor windows.

If you prefer, you can record a macro as you do these steps, and then run that macro each time you want to position your workbooks. Also, there is one drawback to this approach: The ribbon extends across the top of both monitors, which can (once in a while) make getting to some of the tools on the ribbon a bit interesting.

Hi Rodger.
Strange… I just tried to copy from one instance of Excel to another and all went well, - all formatting was also copied across.
But I do remember that there have been occasions when only values were copied across from one instance to another instance. Just now I have not been able to repeat the problem which I know I have had sometimes in the past. .

I believe the clipboard generally is a very unpredictable beast. It has many versions which it holds of what you put into it. It seems to be luck sometimes what version and what formats get used…

I'm a little confused by how you describe this problem. If I open an Excel spreadsheet on one monitor, then open a second spreadsheet from that, and simply drag the new spreadsheet onto the other monitor - it all works fine, and copying and pasting from one to the other works exactly as you'd expect. However, neither is there a problem copying and pasting if you have two instances of Excel open, is there?

Dear Mr Allen,

Thank you for your guide.

Re the different experience of users:

I understand a change was made in either XL2013 or XL2016/Office 365 to how the application and workbooks were managed that enabled display of different workbooks on different monitors. In XL2010 and prior it is not possible to achieve this, so the workaround as described in this tip is as good as it gets.

Alan and Scott,

I believe the issue is not whether you can arrange multiple open
files within a single instance of Excel, but rather how to quickly
and evenly arrange the files.

Of course you can drag and resize the file windows as you like.
It's just how much effort do you want to put into arranging the

In my case, I wrote a macro to do all the arranging across two
monitors with just one short key because I frequently work with
two files and I'm constantly closing and opening the second.

I don't understand the issue. I have Excel 2013. I can open a workbook, then click File | Open and select/open another workbook. It is still in the same instance of Excel but opens in its own window, which you can drag anywhere you want it! And if you have a single monitor you can do the same thing if you size the 2 windows so both fit on the screen. … What am I missing? I know I only have one instance of Excel open because I don't get a warning about personal.xlsb already open when I open the 2nd workbook.

Same as Philip and Keith. Win10 and Office Home & Business 2016. Never been a problem

I have three monitors, all the same size and all side-by-side.
My primary monitor is the center one, and I routinely use Excel
across the center and right monitors.

I got tired of fiddling around with how two or more Excel files
were displayed across the monitors, so I wrote two simple
macros and put them in my Personal.xlsb file.

The first macro displays Excel across two monitors. The files
are spread evenly across the monitors, which for two files is
ideal. Whichever file is active appears in the leftmost position.

The second displays Excel maximized on my center monitor.

I assigned the macros to shortcut keys Ctrl-M and Ctrl-Shift-M,
respectively. "M" for monitor.

You will have to tweak the parameters in the first macro to suit
your monitor resolutions and borders.

Sub FillAllMonitors()

' Purpose: Expand Excel to fill all monitors in side-by-side views.
' Notes: Assigned to keyboard shortcut Ctrl-m (m for monitors)
' Need to adjust the values for MonitorQuantity, MonitorWidth and MonitorHeight to suit your hardware.
' May also need to similarly adjust the values for MonitorEdges and MonitorGutter.
' May also need to similarly adjust the values for OriginX, OriginY and Pixels2Points.
' In the two-monitor view, you may not be able to adjust the overall window so that there are no
' slivers of visible underlying windows (or desktop) outboard of the left and right window edges.
' If so, then center the overall window as best as you can.

Const MonitorQty As Double = 2 'How many side-by-side monitors to spread Excel over

I use DisplayFusion to control 4 monitors and extending any window across any number of monitors can instantly be accomplished with a key combo. For example I use ctrl-win-2 for two monitor spread. The free version can do this, although many more controls are available in the Pro version.

2018-08-15 03:22:17


Don’t understand this. I jus open as many workbooks as I want in the same Excel instance, and they each can work in their separate window. And I’m NOT using Excel365. Works on both Mac and Win10 ...

2018-08-15 03:12:44


I have just read your post regarding using a single instance of excel using two monitors, I am running Excel 365 and Windows 10 and can simply open two or more workbooks (in a single instance of Excel) and drag them as desired to where I want any where on the two monitors without looking at View and Arrange All. Would this be because I am using Excel 365?

2018-04-23 12:41:50


Thanks Allen. That method works okay, but I am trying to work in one worksheet, while the second worksheet is regularly updated through a visual basic routine that is continuously running. The problem is that every time the second worksheet updates, it interrupts the one I am working in. Do you know of any way to resolve this?

2016-09-26 22:11:07


Thanks, it works!!
Your guidance is simple to follow. Thanks and God Bless.

2016-09-06 12:19:27


Thank you again. As you can see, I'm very angry, but very grateful to you. Thank you all over again

2016-08-18 14:48:15


This worked perfectly for me and saved me probably 3 hours messing around back and forth between 3 spreadsheets, Thank you so much!

2016-04-26 07:49:10


This tip is awesome for wanting to view full size spreadsheets at the same time. Thank you.

2014-12-05 14:40:27


I unable to work in two monitors by using separated excel sheets which i have different sources. And i unable to look two excel sheets in two monitors which i have different sources.But i doesn't want "View Two Excel Spreadsheets at Once". I am getting problem in by using number of times Alt+Tab to go another excel sheets.I can open new two separate sheets in two monitors,but while opening my sources i unable to do it.

2014-09-18 15:34:34


AWESOME!!! So excited to be able to do this; I don't know why I didn't think of this before. :) Thank you, thank you!!
