A common Forum question and one that Chandoo has written about a few times is, Does my data overlap with another range?
Last week, Pradhishnair, asked in the Chandoo.org Forums “I need to find if the values between range D2:E2 are overlapping in any of the following rages, if yes then where? (may be row number)”
I answered with an array formula:
{=”Overlap Row S.no. = ” &MIN(IF((D3:$D$41<=E2) *(E3:$E$41>=D2) >0, (A3:$A$41)))}
Which returns ether:
Overlap Row S.no. = x (If there is an overlap)
or
Overlap Row S.no. = 0 (If there is no overlap)
So today in Formula Forensics we will take a look at how the above formula works with a worked example.
Chainage
As always you can follow along with a worked example. This is a subset of Pradhishnair’s Data to simplify the length of the equations, but otherwise is the same as the original post: Download Here
Pradhishnair’s data consists of a list of chainages. Chainages are measurements of distances from a fixed point and relate to a segment of something. Chainage From is to the closest end of the segment and and Chainage To is to the furthest end of the segment and by default these are in order, that is To is always greater than From.
Using this we can check for overlapping data by simply checking if the From is less than the remaining To’s or the To value is greater than the remaining From’s
This is done for each row compared to the remaining rows of data by the array formula
=”Overlap Row S.no.: ” & MIN(IF((D3:$D$41<=E2) *(E3:$E$41>=D2) >0, (A3:$A$41))) Ctrl Shift enter
We can see that the above equation simply joins
“Overlap Row S.no.: “
To the result of
MIN(IF((D3:$D$41<=E2) *(E3:$E$41>=D2) >0, (A3:$A$41)))
Using the & operator
It will return:
Overlap Row S.no. = 0 if there is no overlap
Or
Overlap Row S.no. = x If there is an overlap.
So the function
MIN(IF((D3:$D$41<=E2) *(E3:$E$41>=D2) >0, (A3:$A$41)))
Is used to return the minimum value of an If() formula which is its only component
The If() statement usually has three components:
=If( Condition, Value if True, Value if False)
In our case, I will evaluate Row 2, Particularly Cell G2, against the remaining entries in the two lists.
=If((D3:$D$41<=E2) *(E3:$E$41>=D2) >0, (A3:$A$41))
Condition: (D3:$D$41<=E2) *(E3:$E$41>=D2) >0
Value if True: (A3:$A$41), This is just the S.No. in Column A
Value if False: Note that the If statement has no Value if it is False, I could put any value there eg: -1 or 0, but Excel evaluates it to 0 anyway so it hasn’t been used.
The If Statement says If (D3:$D$41<=E2) *(E3:$E$41>=D2) >0, then return (A3:$A$41)
What the condition is saying is If the To Data in the Current Row, Row 2, is Greater than or equal to the other From Values or the From Data in the Current Row, Row 2, is Less than the other To Value, Then this is True
To check this, in Cell I2, enter =(D3:$D$41<=E2) *(E3:$E$41>=D2) and evaluate it with F9 instead of Enter
Excel returns ={1;1;0;0;0;0;0;0;0}
Excel is showing us that the first and second entries have overlapping data.
Which we can see if we look at the data
The >0 at the end of the (D3:$D$41<=E2) *(E3:$E$41>=D2) >0, transforms the array of 0’s and 1’s to an array of Falses and Trues
To check this, in I3, enter =(D3:$D$41<=E2) *(E3:$E$41>=D2)>0 and evaluate it with F9 instead of Enter
Excel returns ={TRUE;TRUE;FALSE;FALSE;FALSE;FALSE;FALSE;FALSE;FALSE}
Now the If Statement will be True for the first two entries in the array and so will evaluate the Value if True component of the If Formula: (A3:$A$41)
We can check this
In cell I4 enter
=IF((D3:$D$41<=E2) *(E3:$E$41>=D2) >0, (A3:$A$41)) and press F9 instead of Enter
Excel returns
={2;3;FALSE;FALSE;FALSE;FALSE;FALSE;FALSE;FALSE}
Which is the array of S.No’s which match our criteria
Now Min comes in
=MIN({2;3;FALSE;FALSE;FALSE;FALSE;FALSE;FALSE;FALSE})
Min returns the Minimum of these which is 2.
And that is appended to “Overlap Row S.No. = “
To return the answer: Overlap Row S.No. = 2
Which is the first overlapping row with Row 1
Custom Number Formats
You may have noticed that the numbers in Pradhishnair’s worksheet look a bit odd with a + in the middle: eg: D3 displays 142+000
Pradhishnair is using a Custom Number Format of #+000
Select a Cell, eg D2, Press Ctrl 1, Select the Number Tab
If you select these cells and Press F2 Excel will show that the cells value is 142000
But Excel is using the custom Number format of #+000 to display the number with 3 digits after the +

We Need Your Help
I received 3 ideas over the Xmas break from readers, and these will feature in coming weeks.
However I do need more ideas for the rest of 2012 and so I need your help.
If you have a neat formula that you would like to share and explain, try putting pen to paper and draft up a Post as Luke did in Formula Forensics 003. or like above.
If you have a formula that you would like explained but don’t want to write a post also send it in to Chandoo or Hui.
ps: I’m traveling to Esperance; Western Australia for a short holiday with the family but have left a neat Formula Forensic for you for next week.
14 Responses to “How to Add your Macros to QAT or Excel toolbars?”
We have only just got excel 2007 so this is helping me navigate my way through the differences cheers.
For Macro's i always add a Command Button, rename it something obvious, change the colour of it and finally add the following to its View Code section.
Application.Run "MAcro1"
This way anyone opening the file knows what to do if i ever win the lottery and dont make it in 🙂
Hi,
Good article. But I have this problem.
1) Customized QAT with a macro. Macro name = MacroX
2) Runs OK from original location (e.g. C:\TestLoaction1\TestFile.xls)
3) Copy past file to new location (e.g. C:\TestLoaction2\TestFile.xls)
Menu button now fails:
Cannot run the macro "C:\TestLoaction1\TestFile.xls'!MacroX' The macro may not be available in this workbook...
Of course the code is there, and macros are enabled.
Could get it to work after deleting and recreating macro custom buttons. So have to re-assign macro to QAT button every time I move the file?
If I put a form button on he worksheet and assign the macro to that, it's location independent.
Any ideas?
Thanks
@Ron
What you have said is correct
Macros within a worksheet are stored within the worksheet and hence follow it.
Macros referenced by a button in the QAT or elsewhere are locaed in a file and if that file is moved the linkages don't follow.
The easiest way around this is to store all your macros in a location that doesn't move and is in fact reloaded everytime that Excel starts and that is called the Personal.xlsx/b file.
These are refered to several time at Chandoo.org or have a read of
http://www.rondebruin.nl/personal.htm
or
http://office.microsoft.com/en-us/excel-help/deploy-your-excel-macros-from-a-central-file-HA001087296.aspx
In Excel 2003 and prior versions, a button added to the Toolbar maintained a DYNAMIC link to the file (e.g. Personal.xlsb) holding the assigned macro, such that if the file was relocated for any reason (by using Excel's native Save As command rather than just moving it via Windows Explorer), the link between the button and the file was updated.
I expected the same to occur with Excel 2007+, but alas, Microsoft in their infinite wisdom have removed another feature useful to advanced users (just as they did by removing the ability to design your own buttons)!!
So having just done some reorganisation of my files, I now have to remove and recreate every friggin macro button on my QAT (I have lots) - what a pain in the proverbial!!
Hi Hui,
Thanks for the help, that's really useful.
1) The macros I'm adding are for one specific Excel application, so I really wanted the macros to follow the file
2) I didn't want to have to pass other files around too and have users installing those - either Personal.xlsx/b or as an Add-In.
3) I realise now that the QAT additions will appear for other Excel workbooks in which I don't want the macros available.
So, it looks like I need to keep it local, by using a button on the worksheet. Unless you can suggest any way of adding to menus just for a specific workbook.
Thanks again for your help. Great site, so I'll be signing up for the emails.
Ron
I know I'm a little late jumping on this post, but wondering if anyone knows how to add a UDF to the QAT? I've saved my UDF in my personal workbook, but it does not show up in my list when I choose Macros when customizing my QAT. Suggestions? Thanks!!
@Cheryl: UDFs cannot be accessed like Macros. You can use them from other macros or from worksheet cells as formulas...
@David: If you save your macros file and then install it as an add-in then it will be always available for you.
The instructions work great when you are creating a new file, and it is still open. I find that I can't access macros after I've saved a file as an xlam and closed it. When I reopen the xlam, either by browsing to it, or by having it set to open as an addin using Excel Options, the macros are no longer available in the macros list when I go to edit the QAT. Any way around that?
[...] Add this macro as a button to Quick Access Toolbar [...]
I need to create a button that will run a macro. Once you click the button it needs to open up a browser asking you to select a report/file. Once you select the file, it will run the macro on the selected file and then save it as a new report with a name and the current date. I created the macro to sort/modify the report but I do not know how to do what I mentioned above. I hope this makes sense.
I'm having trouble adding a macro to the QAT. I've done everything up to step 5 but my macro isn't showing up. What am I doing wrong?
[...] Add Macros to Quick Access Toolbar (works in Excel 2003 & above) [...]
Hi,
Thank you for the explanation. Very useful for a recent switcher from office 2003 to office 2010.
My follow-up question is: in Excel (or ppt) 2010, can you customize the macro button that you put in the QAT?
In office 2003, once you chose the custom button for your Macro, you could then edit pixel by pixel the said button.
For instance, I've created 2 Macros in PPT that are converting all my slides to either English or French language, so I'd like one button to show EN and the other FR... that would be more meaningful that any of the possible "custom" office 2010 buttons
I read all the post and one important aspect to the QAT was never mentioned. That is, you have a macro driven worksheet that you want to share with other. You have customized the QAT with two icons to run the macros (VBA programs in reality). However, when the others receive the workbook, the icons are no where to be found. It's my understanding those "customized buttons" have been saved to an outside file, Excel.qat. QUESTION: Could one simply attach that file to your email, along with the worksheet, and tell the recipients to copy that file to correct location on their computer - C:\Users\\AppData\Local\Microsoft\Office|\
Would the customize macro buttons then appear in the worksheet and, more importantly, work? Thanks for your thoughtfulness and thanks for well written instructions Chandoo!
