I would like to know if it would be possible to use the IFERROR, INDEX, MATCH function on below scenario.
D2:=INDEX($A$2:$A$16, MATCH(0, COUNTIF($D$1:$D1, $A$2:$A$16), 0))
E2: =IFERROR(INDEX($B$2:$B$16, MATCH(0, COUNTIF($D2:D2,$B$2:$B$16)+IF($A$2:$A$16<>$D2, 1, 0), 0)), "")
H2: =IFERROR(INDEX($C$2:$C$16, MATCH(0, COUNTIF($D2:D2,$C$2:$C$16)+IF($A$2:$A$16<>$D2, 1, 0), 0)), "")
I2: =IFERROR(INDEX($C$2:$C$16, MATCH(0, COUNTIF($D2:H2,$C$2:$C$16)+IF($A$2:$A$16<>$D2, 1, 0), 0)), "")
Based on the data of Countries and Cities filled in yellow on the left, by using the IFERROR, INDEX, MATCH formula I managed to get all the data I need. Now if there are more than 3 City, I want for the excel to continue the list of cities by creating another row under it as example of row filled in red.
I hope it makes sence. Let me know if it's possible.
You did tag vba as well as excel-formula so give this a try

I have a portfolio report I build from VBA code on monthly and ad-hoc basis. It works fine today, but the underlying VBA is far from optimized. The code sniplet below is repeated 5 times as there are 5 projects in the system now, but it will grow to 50 shortly. Is there anyone that have suggestions as to how I can utilize VBA more elegantly performing the copying to the locations specified in the code (see sniplet below)

It is assumed that the data in the data sheet is repeated as shown in the following figure.
I am fairly new to Excel and VBA. I wrote a code that separates a line of data into multiple sections which then adds headers, colors, and plots.
The problem is when I have many lines of data. My code runs just fine when I have about 4000 lines of data, but I get say about 10000 lines, Excel freezes and does not respond anymore. The code is fairly long and I do expect anyone to read the entire thing.
My doubts are that excel does not respond and crashes because there is a watch-dog timer that times the execution of the code and if it does not receive anything back then it crashes. This is only a guess.
Here is a few lines of the actual data that I need to filter and everything.

All of your Worksheets("x").Activate are totally unnecessary, are slowing your code significantly and are begging for inexplicable errors later when you forget to activate the correct sheet or your bored user starts clicking around during execution because it's taking too long. Declare some Worksheet variables and work with those.
Dim DataSheet as Worksheet
ActiveSheet.Name = "Data"
Set DataSheet = ActiveSheet
Dim PlotSheet as Worksheet
Set PlotSheet as Worksheets.Add
Plotsheet.Name = "Plots"
Dim ErrorSheet as Worksheet
Set ErrorSheet = Worksheets.Add
ErrorSheet.Name = "Errors"
count = Datasheet.Cells(1, 1).CurrentRegion.Rows.count
'GET RID OF THIS EVERYWHERE!!! Worksheets("Errors").Activate
'Save the row number and the monitor number where the error was founf
With ErrorSheet
.Cells(errorCount, 1).Value = "Voltage error in row"
.Cells(errorCount, 2).Value = count - i + shiftDown
.Cells(errorCount, 3).Value = "in column"
.Cells(errorCount, 4).Value = (k * 10) + 8
.Cells(errorCount, 5).Value = "in Monitor"
.Cells(errorCount, 6).Value = k + 1
.Cells(errorCount, 7).Value = "The recorded data was"
'Note subtle change here:
DataSheet.Cells(count - i + shiftDown, (k * 10) + 8).Copy .Cells(errorCount, 8)
'Note: explicitly setting "datasheet" as the destination and using the "With" to save some typing on the ".Cells" call.
'You could explicitly type the "ErrorSheet" to make it more clear
'an even better version is:
.cells(errorCount, 8) = DataSheet.Cells(count - i + shiftDown, (k * 10) + 8)
End With
Continue to do that everywhere. Future you will appreciate current you...
Every time you're doing a Sheet("x").Activate eliminate that line and explicitly add a reference to the appropriate worksheet variable you declared earlier.
Every time you have an unqualified Sheets or Cells or Range call, make it an explicit reference by prepending the appropriate worksheet variable. Future you will appreciate the fact that you can see exactly what worksheet you're referencing. Sure, there may be some extra typing involved, but that extra typing significantly reduces the chance of inserting very subtle and difficult to find bugs.
Using .Copy is very slow for single cells. It does gain a speed advantage if you're copying large blocks of cells in a single go (somewhere in the neighborhood of 3-5k cells in a single copy statement vs a loop through setting individual cell values).
As Uri Goren pointed out setting Application.Calculation = False will definitely improve your speed. I'd recommend not setting Application.ScreenUpdating = False until after your code is 100% functional and not generating any errors. Once you're at that point, it's a great thing to do.
At this point in your code you may want to add the indicated line:
'Iterate through the points separating the Data
For i = 0 To count - 1
'Add this line:
Application.StatusBar = "Separating points #" & i
Put a similar message just inside the top of each of your large loops. You'll likely see that your code isn't hanging, just taking a long time to process. Plus you'll have an update that your user can watch so (s)he'll know it isn't hung and is still doing something.
At the end of your code put:
Application.StatusBar = ""
To clear the message so you get your normal Excel StatusBar functionality returned.
Add these two lines at the beginning of the subroutine:
Application.ScreenUpdating = False
Application.Calculation = xlCalculationManual
And these 2 lines before the end of the subroutine
Application.Calculation = xlCalculationAutomatic
Application.ScreenUpdating = True
It should speed up your code significantly
