Often we want to determine what type of object has been selected in Excel. It helps with error checking prior to running a piece of code.
This action is just a just a single line of code:
Sub testSelection() MsgBox TypeName(Selection) End Sub
Incorporate the check into a Select statement
If you want to treat selection types differently a case statement similar to the one below may be useful.
Sub testSelection() Select Case TypeName(Selection) Case "ChartArea", "ChartTitle" 'Do something to the Chart Case "Range" 'Do something to the range Case Else 'Oh dear, not an acceptable selection. 'Do something else. End Select End Sub
Do you know the fastest way to learn foreign languages? It is to read, write, speak, and think in that language as often as possible. Apart from speaking, programming languages are no different. The more you immerse yourself in that language, the faster you will pick it up.
Therefore, what most people like you need is lots of examples that you can practice. That is why the 100 Excel VBA Macros eBook exists. It’s the book for all Excel users who want to learn how to read and write Excel macros, save time, and stand out from their peers. The book contains:
- 100 example codes to practice reading and writing macros that will embed the language into your thinking.
- An introduction to macros in Excel to ensure you can implement the VBA code in the book even if you have no prior knowledge.
- Consistent code layout between examples to enable you to understand the structure and easily customize the code to meet your needs.
- Downloadable workbook containing all the source code, so the examples can be added to your project to give you the benefit of VBA straight away.
Allowing any part of an object to be selected
Some objects, such as Charts can be difficult to select. Depending where the users clicks, the Selection might be on the Series, Legend or ErrorBars. All of these are parts of the ChartObject. To work with the chart no matter where the user clicked, move up the Document Object Model until the TypeName is “ChartObject”. Look at the code below for an example.
'Create a variable called tempSelection to hold the selection Dim tempSelection As Object Set tempSelection = Selection 'Loop keep finding the parent of the tempSelection until it reaches 'the top of the Document Object Model. Do While TypeName(tempSelection) <> "Application" 'If the tempSelection equals ChartObject exit the loop 'else find the parent of the tempSelection and loop again If TypeName(tempSelection) = "ChartObject" Then Exit Do Else Set tempSelection = tempSelection.Parent End If Loop 'If any part of an embedded chart was selected the MsgBox will show "ChartObject" 'if not it will show "Application" MsgBox TypeName(tempSelection)
Charts can also be sheets, rather than embedded. Their behaviours are slightly different, so differentiating between a chart sheet and embedded chart is important.
A chart sheet has the following Document Object Model structure.
Application -> Workbook -> Chart -> ChartArea ...
An embedded chart has the following Document Object Model structure.
Application -> Workbook -> Worksheet -> ChartObject -> Chart -> ChartArea ...
There is an easy way to tell the difference between the two types of Charts.
- Only embedded charts have a ChartObject
- If the parent of the Chart is a Workbook it is a chart sheet,
The code below will show a message of Chart if the selection is a chart sheet.
Dim tempSelection As Object Set tempSelection = Selection Do While TypeName(tempSelection) <> "Application" If TypeName(tempSelection) = "Chart" And _ TypeName(tempSelection.Parent) = "Workbook" Then Exit Do Else Set tempSelection = tempSelection.Parent End If Loop MsgBox TypeName(tempSelection)
A list of all possible selections
Based on information within the Object Browser, I believe the complete list of possible selections would be:
- Axis Title
It is not necessary to treat each selection differently, similar objects can be treated in the same way. See the Select Case example in the code above.

Do you need help adapting this to your needs?
I’m guessing the examples in this post didn’t exactly meet your situation. We all use Excel differently, so it’s impossible to write a post that will meet everybody’s needs. By taking the time to understand the techniques and principles in this post (and elsewhere on this site) you should be able to adapt it to your needs.
But, if you’re still struggling you should:
- Read other blogs, or watch YouTube videos on the same topic. You will benefit much more by discovering your own solutions.
- Ask the ‘Excel Ninja’ in your office. It’s amazing what things other people know.
- Ask a question in a forum like Mr Excel, or the Microsoft Answers Community. Remember, the people on these forums are generally giving their time for free. So take care to craft your question, make sure it’s clear and concise. List all the things you’ve tried, and provide screenshots, code segments and example workbooks.
- Use Excel Rescue, who are my consultancy partner. They help by providing solutions to smaller Excel problems.
