Creating a list of headings, sub-headings and sub-subheadings in Excel - excel-formula

I am looking to make a list of heading type 1, sub-heading type 2 and sub-sub-heading type 3, and each subsequent instance of a heading increments in excel. e.g.
Outcome 1
Output 1.1
Activity 1.1.1
Activity 1.1.2
Output 1.2
Activity 1.2.1
Activity 1.2.2
Activity 1.2.3
Outcome 2
Output 2.1
Activity 2.1.1
etc
Here is my formula - getting to be a complicated nested IF statement:
IF([#Column1]="","",
IF([#Column1]="Outcome", "Outcome " & COUNTIF(tbOOA[[#Headers],[Column1]]:[#Column1], [#Column1]),
IF([#Column1]="Output","Output "& COUNTIF(tbOOA[[#Headers],[Column1]]:[#Column1],"Outcome") ***&"."&*** COUNTIF(tbOOA[[#Headers],[Column1]]:[#Column1],[#Column1]),
"Activity " & "serious help")))
In Column 1, choose from a list of 'Outcome', 'Output', or 'Activity'.
In column 2, calculate the appropriate number, e.g. Output 1.2
If the row is empty, then nothing. - Fine
If it is "Outcome", count from the header until current row for the number of instances of "Outcome". - Fine
Else if it is "Output", count the number of "Outcome"s there are. - Fine
This is where it falls apart. Trying to calculate the number after the "." (bold and italic)
I need to count the # of instances of "Output", but then this has to reset to 1 each time there is a new 'Outcome'.
The logic I'm trying to follow is:
(# of "Outputs" from the table header until the current row) minus
(# of "Outputs" from the table header until the last instance of "Outcome")
I've tried several attempts at calculating row number, but everything has been problematic.
The logic is the same for activities, though will complicate the formula even more and I haven't bothered to start on that until I can get level 2 sorted.
Does anyone know of a similar problem/solution?

If you are open to using hidden helper columns, the formulas become much more manageable. Use Column A to hold your "Outcome", "Output", and "Activity" data.
Then use column B to deal with Outcome numbers, column C to deal with Output numbers, and column D to deal with Activity numbers. Merge the final results together in Column E.
In B1, C1, and D1, manually write in the first values (1, 0, and 0).
Then, fill down starting from B2 with the following:
=IF(A2="Outcome",B1+1,B1)
This works by incrementing only if you have found your next Outcome.
Fill down from C2 with the following:
=IF(A2="Outcome",0,IF(A2="Output",C1+1,C1))
This works by incrementing only if you have found your next Output. It resets to 0 if you have a new Outcome.
Then fill down from D2 with
=IF(OR(A3="Outcome",A3="Output"),0,IF(A3="Activity",D2+1,D2))
It's very similar to the prior formula, but resets on an Outcome or an Output.
Finally, in D4, merge it all together with
=B1&IF(C1>0,"."&C1&IF(D1>0,"."&D1,""),"")
& is a string concatenate operation. By checking if the inner values are 0, we only concatenate . and the next number if the next number is non-zero.

I had a similar problem, where I wanted to create the multi-level heading numbers based on the indentation of list of texts. So the numbers must be generated automatically with a user-defined formula (UDF) like below:
For this to work, you must type ="1" in cell A2. The same formula in A3 (below) must be copied down to A4:A14.
=NextLevelNum(A2;IndentLevel(B3))
Function IndentLevel I took from https://professor-excel.com/how-to-return-the-indentation-of-a-cell-in-excel/
Function NextLevelNum I did myself. All code below.
Option Explicit
Public Function IndentLevel(Ref As Range) As Long
Application.Volatile
IndentLevel = Ref.IndentLevel
End Function
Public Function NextLevelNum(prevNumRef As Range, level As Integer) As String
Dim prevNum As String
Dim nums() As String
Dim prevLevel As Integer
prevNum = prevNumRef.Value
nums = Split(prevNum, ".")
prevLevel = UBound(nums) + 1
' Ensure 1 <= level <= prevLevel +1
level = WorksheetFunction.Max(level, 1)
level = WorksheetFunction.Min(level, prevLevel + 1)
ReDim Preserve nums(0 To level - 1)
If level = prevLevel + 1 Then
nums(level - 1) = "1"
Else
nums(level - 1) = CStr(CInt(nums(level - 1)) + 1)
End If
NextLevelNum = Join(nums, ".")
End Function

Dynamic Range division with two variables

I'm trying to complete division for a dynamic range with two variables and it keeps dividing the dynamic range by the last number in the range. Below is my VBA code.
For i = 2 To 8
For r = 13 To 19
If ThisWorkbook.Sheets("Sheet1").Cells(i, 28) = "" Then
ThisWorkbook.Sheets("Sheet1").Cells(r, 28) = ""
Else
ThisWorkbook.Sheets("Sheet1").Cells(r, 28) = ThisWorkbook.Sheets("Sheet1").Cells(i, 28) / Range("$AB$8")
End If
Next r
Next i
Essentially it is dividing the last i value (Cell row 8) by the Range("$AB$8") (cells row 19).
What I would like to happen is the values in rows i to divide by Range("$AB$8")....in other words the value in cell (2,28)/ab8, (3/28)/ab8, (4,28)/ab8 etc etc.
It current is taking the value in cell (8,28) dividing it by ab8...and applying it to all defined r rows.
There are a number of issues here - all of which are small tweaks but end up with the wrong result you are seeing.
Your example code is not a dynamic range. You have hardcoded Cells(AB2:AB8) and Cells(AB13:AB19). You just did it in a way that is not obvious.
Also not very obvious is that you are writing the results to a single column. See the pattern here:
Loop 1: i = 2, results may be writing to Cells(AB13:AB19)
[…]
Loop 7: i = 8, results may be writing to Cells(AB13:AB19)
I said "may" because you have the If statement.
Depending on what you really want to happen, the code can be amended.
Instead off the first loop put a conditional there (e.g. If all cells
in that range are blank then …, or if any cells are blank then ...)
Use an Exit For after fixing the first blank loop
Also address the column (i.e. results spread across multiple columns)
Use a single loop (For i = 2 to 8 … and then adjust r according to i… r = i+12)

Excel - Multiple Cell Calculation

I'm a teacher and trying to create a mark sheet the problem I have is that assignments are marked using different schemes (i.e. % [1 - 100], Level [1 -4], Letter Grade [F - A]). The problem I have is that I only want to report using one marking scheme and need to convert or calculate the other marking schemes based on the scheme there is it is marked.
I've made an excel worksheet which contains a student names and assignments. The sheet then has 3 other columns, one representing each scheme "Letter", "Level", Percentage a column for each scheme. Now, at any given time there is going to be a value in one of the 'scheme' columns - I need excel to automatically or by macro calculate the appropriate value into the other cells.
For example, there are three assignments each marked with a different scheme on the same sheet.
Assignment 1 - %
Assignment 2 - Level
Assignment 3 - Letter Grade
How can I get excel to check which mark value exists and then populate/calculate the other two the corresponding values.
Mike got 80% (%) on Assignment 1, but I want excel to populate the level column and letter column with the corresponding values at the same time Level 3 on Assignment 2 excel to calculate corresponding percentage and letter and at the same time for a Letter A on Assignment 3 the corresponding % and level should be calculated.
Don't know if this is possible or makes sense, but I tried VLOOKUP and was not successful because I have to do it all manually - I'm aiming for an automated process.
Sorry if it is not clear or confusing...but I've been at this for two days with no luck and not even sure if what I'm doing is possible.
of course it should be first assessed the translation of one rating system to the other and then assume those algorithms to shift between rating grades types
one of the possible approaches could be the following:
Option Explicit
Sub main()
Dim grades As Variant, levels As Variant
Dim cell As Range
Dim index As Double
grades = Array("F", "E", "D", "C", "B", "A")
levels = Array(1, 2, 3, 4)
For Each cell In Intersect(Range("A:C"), ActiveSheet.UsedRange).Offset(1).SpecialCells(xlCellTypeConstants)
Select Case cell.Column
Case 1 '%
index = cell.value / 100
cell.Offset(, 1).value = GetRate(index, levels)
cell.Offset(, 2).value = GetRate(index, grades)
Case 2 ' Level
index = InStr(Join(levels, ""), cell.value) / Len(Join(levels, ""))
cell.Offset(, -1).value = index * 100
cell.Offset(, 1).value = GetRate(index, grades)
Case 3
index = InStr(Join(grades, ""), cell.value) / Len(Join(grades, ""))
cell.Offset(, -2).value = index * 100
cell.Offset(, -1).value = GetRate(index, levels)
End Select
Next
End Sub
Function GetRate(index As Double, rates As Variant)
GetRate = rates(WorksheetFunction.Max(Round(index * (UBound(rates) - LBound(rates) + 1), 0) - 1, 0))
End Function
due to the simplicity of the translation algorithm it doesn't provide a bijective relationship between grading systems with different spans, but it can get you closer to your goal
Create a table like so (you can add more rows if you need to define +/- scores like "B+", etc.). The key here is sort the table ascending by %, with each row being the minimum score needed for the corresponding Level/Letter Grade.
Then, you can use VLOOKUP formula against this table, like so to get the Level:
=VLOOKUP(F2,$A$1:$C$7,2,TRUE)
And like so, to get the Letter Grade:
=VLOOKUP(F2,$A$1:$C$7,3,TRUE)
This takes advantage of the True parameter in the VLOOKUP function, which will return an approximate match (and assumes data is sorted ascending). So, when you enter a value like "81%", it returns the nearest row which is not greater than 81%, so it will return data from row 5. Likewise, 12% will return data from row 2, 75% from row 4, etc.
And your results:
You may need to use two tables if you can't 1:1 map the Level/Letter Grade to a Percent row, but the idea would be the same.

How can I lookup data from one column, when the value I'm referencing changes columns?

I want to do an INDEX-MATCH-like lookup between two documents, except my MATCH's index array doesn't stay in one column.
In Vague-English: I want a value from a known column that matches another value that may be found in any column.
Refer to the image below. Let's call everything to the left of the bold vertical line on column H doc1, and the right side will be doc2.
Doc2 has a column "Find This", which will be the INDEX's array. It is compared with "ID1" from doc1 (Note that the values in "Find This" will not be in the same order as column ID1, but it's easier to undertsand this way).
The "[Result]" column in doc2 will be the value from doc1's "Want This" column from the row that matches "FIND THIS" ...However, sometimes the value from "FIND THIS" is not in the "ID1" column, and is instead in "ID2","ID3", etc.
So, I'm trying to generate Col K from Col J. This would be like pressing Ctrl+F and searching for a value in Col J, then taking the value from Col D in that row and copying it to Col K.
I made identical values from a column the same color in the other doc to make it easier to visualize where they are coming from.
Note also that in column F of doc1, the same value from doc2's "Find This" can be found after some other text.
Also note that the column headers are only there as examples, the ID columns are not actually numbered.
I would simply hard-code the correct column to search from, but I'm not in control of doc1, and I'm worried that future versions may have new "ID" columns, with other's being removed.
I'd prefer this to be a solution in the form of a formula, but VB will do.
To generate column K based on given values of column J then you could use the following:
=INDEX(doc1!$D$2:$D$14,SUMPRODUCT((doc1!$B$2:$H$14=J2)*ROW(doc1!$B$2:$H$14))-1)
Copy that formula down as far as you need to go.
It basically only returns the row of the where a matching column J is found. we then find that row in the index of your D range to get your value in K.
Proof of concept:
UPDATE:
If you are working with non unique entities n column J. That is the value on its own can be found in multiple rows and columns. Consider using the following to return the Last row where there J value is found:
=INDEX(doc1!$D$2:$D$14,AGGREGATE(14,6,(doc1!$B$2:$H$14=J2)*ROW(doc1!$B$2:$H$14),1)-1)
UPDATE 2:
And to return the first row where what you are looking in column J is found use:
=INDEX($D$2:$D$14,AGGREGATE(15,6,1/($B$2:$H$14=J2)*ROW($B$2:$H$14)-1,1))
Thanks to Scott Craner for the hint on the minimum formula.
To determine if you have UNIQUE data from column J in your range B2:H14 you can enter this array formula. In order to enter an array formula you need to press CTRL+SHFT+ENTER at the same time and not just ENTER. You will know you have done it right when you see {} around your formula in the formula bar. You cannot at the {} manually.
=IF(MAX(COUNTIF($B$2:$H$14,J2:J14))>1,"DUPLICATES","UNIQUE")
UPDATE 3
AGGREGATE - A relatively new function to me but goes back to Excel 2010. Aggregate is 19 functions rolled into 1. It would be nice if they all worked the same way but they do not. I think it is functions numbered 14 and up that will perform the same way an array formula or a CSE formula if you prefer. The nice thing is you do not need to use CSE when entering or editing them. SUMPRODUCT is another example of a regular formula that performs array formula calculations.
The meat of this explanation I believe is what is happening inside of the AGGREGATE brackets. If you click on the link you will get an idea of what the first two arguments are. The first defines which function you are using, and the second tell AGGREGATE how to deal with Errors, hidden rows, and some other nested functions. That is the relatively easy part. What I believe you want to know is what is happening with this:
(doc1!$B$2:$H$14=J2)*ROW(doc1!$B$2:$H$14)
For illustrative purpose lets reduce this formula to something a little smaller in scale that does the same thing. I'll avoid starting in A1 as that can make life a little easier when counting since it the 1st row and first column. So by placing the example range outside of it you can see some more special considerations potentially.
What I want to know is what row each of the items list in Column C occurs in column B
| B | C
3 | DOG | PLATYPUS
4 | CAT | DOG
5 | PLATYPUS |
The full formula for our mini example would be:
{=($B$3:$B$5=C2)*ROW($B$3:$B$5)}
And we are going to look at the following as an array
=INDEX($B$3:$B$5,AGGREGATE(14,6,($B$3:$B$5=C2)*ROW($B$3:$B$5),1)-2)
So the first brackets is going to be a Boolean array as you noted. Every cell that is TRUE will TRUE until its forced into a math calculation. When that happens, True becomes 1 and False becomes 0.I that formula was entered as a CSE formula and place in D2, it would break down as follows:
FALSE X 3
FALSE X 4
TRUE X 5
The 3, 4 and 5 come from ROW() returning the value of the row number that it is dealing with at the time of the array math operation. Little trick, we could have had ROW(1:3). Just need to make sure the size of the array matches! This is not matrix math is just straight across multiplication. And since the Boolean is now experiencing a math operation we are now looking at:
0 X 3 = 0
0 X 4 = 0
1 X 5 = 5
So the array of {0,0,5} gets handed back to the aggregate for more processing. The important thing to note here is that it contains ONLY 0 and the individual row numbers where we had a match. So with the first aggregate formula, formula 14 was chosen which is the LARGE function. And we also told it to ignore errors, which in this particular case does not matter. So after providing the array to the aggregate function, there was a ,1) to finish off the aggregate function. The 1 tells the aggregate function that we want the 1st larges number when the array is sorted from smallest to largest. If that number was 2 it would be the 2nd largest number and so on. So the last row or the only row that something is found on is returned. So in our small example it would be 5.
But wait that 5 was buried inside another function called Index. and in our small example that INDEX formula would be:
=INDEX($B$3:$B$5,AGGREGATE(...)-2)
Well we know that the range is only 3 rows long, so asking for the 5th row, would have excel smacking you up side the head with an error because your index number is out of range. So in comes the header row correction of -1 in the original formula or -2 for the small example and what we really see for the small example is:
=INDEX($B$3:$B$5,5-2)
=INDEX($B$3:$B$5,3)
and here is a weird bit of info, That last one does not become PLATYPUS...it becomes the cell reference to =B5 which pulls PLATYPUS. But that little nuance is a story for another time.
Now in the comments Scott essentially told me to invert for the error to get the first row. And this is important step for the aggregate and it had me running in circles for awhile. So the full equation for the first row option in our mini example is
=INDEX($B$3:$B$5,AGGREGATE(15,6,1/($B$3:$B$5=C2)*ROW($B$3:$B$5),1)-2)
And what Scott Craner was actually suggesting which Skips one math step is:
=INDEX($B$3:$B$5,AGGREGATE(15,6,ROW($B$3:$B$5)/($B$3:$B$5=C2),1)-2)
However since I only realized this after writing this all up the explanation will continue with the first of these two equations
So the important thing to note here is the change from function 14 to function 15 which is SMALL. Think of it a finding the minimum. And this time that 6 plays a huge factor along with the 1/. So our array in the middle this time equates to:
1/FALSE X 3
1/FALSE X 4
1/TRUE X 5
Which then becomes:
1/0 X 3
1/0 X 4
1/1 X 5
Which then has excel slapping you up side the head again because you are trying to divide by 0:
#div/0 X 3
#div/0 X 4
1/1 X 5
But you were smart and you protected yourself from that slap upside the head when you told AGGREGATE to ignore error when you used 6 as the second argument/reference! Therefore what is above becomes:
{5}
Since we are performing a SMALL, and we passed ,1) as the closing part of the AGGREGATE, we have essentially said give me the minimum row number or the 1st smallest number of the resulting array when sorted in ascending order.
The rest plays out the same as it did for the LARGE AGGREGATE method. The pitfall I fell into originally is I did not use the 1/ to force an error. As a result, every time I tried getting the SMALL of the array I was getting 0 from all the false results.
SUMPRODUCT works in a very similar fashion, but only works when your result array in the middle only returns 1 non zero answer. The reason being is the last step of the SUMPRODUCT function is to all the individual elements of the resulting array. So if you only have 1 non zero, you get that non zero number. If you had two rows that matched for instance 12 and 31, then the SUMPRODUCT method would return 43 which is not any of the row numbers you wanted, where as aggregate large would have told you 31 and aggregate small would have told you 12.
Something like this maybe, starting in K2 and copied down:
=IFERROR(INDEX(D:D,MAX(IFERROR(MATCH(J2,B:B,0),-1),IFERROR(MATCH(J2,E:E,0),-1),IFERROR(MATCH(J2,G:G,0),-1),IFERROR(MATCH(J2,H:H,0),-1))),"")
If you want to keep the positions of the columns for the Match variable, consider creating generic range names for each column you want to check, like "Col1", "Col2", "Col3". Create a few more range names than you think you will need and reference them to =$B:$B, =$E:$E etc. Plug all range names into Match functions inside the Max() statement as above.
When columns are added or removed from the table, adjust the range name definitions to the columns you want to check.
For example, if you set up the formula with five Matches inside the Max(), and the table changes so you only want to check three columns, point three of the range names to the same column. The Max() will only return one result and one lookup, even if the same column is matched several times.
I came up with a vba solution if I understood correctly:
Sub DisplayActiveRange()
Dim sheetToSearch As Worksheet
Set sheetToSearch = Sheet2
Dim sheetToOutput As Worksheet
Set sheetToOutput = Sheet1
Dim search As Range
Dim output As Range
Dim searchCol As String
searchCol = "J"
Dim outputCol As String
outputCol = "K"
Dim valueCol As String
valueCol = "D"
Dim r As Range
Dim currentRow As Integer
currentRow = 1
Dim maxRow As Integer
maxRow = sheetToOutput.UsedRange.Rows.Count
For currentRow = 1 To maxRow
Set search = Range("J" & currentRow)
For Each r In sheetToSearch.UsedRange
If r.Value <> "" Then
If r.Value = search.Value Then
Set output = sheetToOutput.Range(outputCol & currentRow)
output.Value = sheetToSearch.Range(valueCol & currentRow).Value
currentRow = currentRow + 1
Set search = sheetToOutput.Range(searchCol & currentRow)
End If
End If
Next
Next currentRow
End Sub
There might be better ways of doing it, but this will give you what you want. We assume headers in both "source" and "destination" sheets. You will need to adapt the "Const" declarations according to how your sheets are named. Press Control & G in Excel to bring up the VBA window and copy and paste this code into "This Workbook" under the "VBA Project" group, then select "Run" from the menu:
Option Explicit
Private Const sourceSheet = "Source"
Private Const destSheet = "Destination"
Public Sub FindColumns()
Dim rowCount As Long
Dim foundValue As String
Sheets(destSheet).Select
rowCount = 1 'Assume a header row
Do While Range("J" & rowCount + 1).value <> ""
rowCount = rowCount + 1
foundValue = FncFindText(Range("J" & rowCount).value)
Sheets(destSheet).Select
Range("K" & rowCount).value = foundValue
Loop
End Sub
Private Function FncFindText(value As String) As String
Dim rowLoop As Long
Dim colLoop As Integer
Dim found As Boolean
Dim pos As Long
Sheets(sourceSheet).Select
rowLoop = 1
colLoop = 0
Do While Range(alphaCon(colLoop + 1) & rowLoop + 1).value <> "" And found = False
rowLoop = rowLoop + 1
Do While Range(alphaCon(colLoop + 1) & rowLoop).value <> "" And found = False
colLoop = colLoop + 1
pos = InStr(Range(alphaCon(colLoop) & rowLoop).value, value)
If pos > 0 Then
FncFindText = Mid(Range(alphaCon(colLoop) & rowLoop).value, pos, Len(value))
found = True
End If

If aNumber <= 26 Then
alphaCon = (Mid$(letterArray, aNumber, 1))
Else
If aNumber Mod 26 = 0 Then

Multiply two 100-Digit Numbers inside Excel Using Matrix

I want to multiply two 100-Digit Numbers In Excel using matrix. The issue in Excel is that after 15-digit, it shows only 0. So, the output also need to be in a Matrix.
1st Number: "9999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999"
2nd Number: "2222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222"
Output: "22222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222217777777777777777777777777777777777777777777777777777777777777777777777777777777777777777777777777778"
This may be what OP was after. I thought I would try a naive multiplication method to see how long it would take to run. The answer is less than a second for two 100-digit numbers. You have to select the output range (i.e. A3:GR3 for a 200-digit result) and enter the formula containing the input ranges as an array formula using CtrlShiftEnter e.g.
=Multiply(A1:CV1,A2:CV2)
for two 100-digit numbers.
The method is basically just a simulation of school maths long multiplication, except that the intermediate rows are not stored but immediately added to the answer thus saving a lot of space.
The utility of it is obviously not that it is a replacement for the Karatsuba method, but it is a simple verifiable method which could be used for one-off calculations.
Currently limited to multiplication of rows containing more than one cell (so if you wanted to multiply by a single digit number, would have to enter it as e.g. 09).

OK it might work like this:-
(1) You need to concatenate your numbers into a string because that's what you need as the input to your function. Native Excel won't do concatenation on arrays so you need a UDF like this one. So B2 contains
=concat(D1:G1)
(2) The output from the function is a string so you need to split it back into separate cells. You could use another UDF or a formula like this one copied across:-
=IF(COLUMNS($C3:C3)>LEN($B$3),"",VALUE(MID($B3,COLUMNS($C3:C3),1)))
So for the simple example it would look like this:-
But I might have got the wrong end of the stick completely.
Place your arrays into A1:A100 and B1:B100, then use three formulas:
1) In C2:C200 enter this as an array formula:
=MMULT(IFERROR(INDEX(A1:A100*TRANSPOSE(B1:B100),(ROW(INDIRECT("1:"&ROWS(A1:A100)*2-1))>0)+TRANSPOSE(ROW(INDIRECT("1:"&ROWS(A1:A100))))-1,MOD(ROW(INDIRECT("1:"&ROWS(A1:A100)*2-1))-TRANSPOSE(ROW(INDIRECT("1:"&ROWS(A1:A100)))),ROWS(A1:A100)*2-1)+1),0),SIGN(A1:A100+1))
2) In D1 enter =C1+INT(D2/10) and fill down to D200.
3) In E1 enter =MOD(D1,10) and fill down to D200.
E1:E200 will contain the answer.

Excel VBA - Referring between ranges

Here's my problem:
I have two ranges, r_products and r_ptypes which are from two different sheets, but of same length i.e.
Set r_products = Worksheets("Products").Range("A2:A999")
Set r_ptypes = Worksheets("SKUs").Range("B2:B999")
I'm searching for something in r_products and I've to select the value at the same position in r_ptypes. The result of Find method is being stored in cellfound. Now, consider the following data:
Sheet: Products
A B C D
1 Product
2 S1
3 P1
4 P2
5 S2
6 S3
Sheet: SKUs
A B C D
1 SKU
2 S1-RP003
3 P1-BQ900
4 P2-HE300
5 S2-NB280
6 S3-JN934
Now, when I search for S1, cellfound.Row gives me value 2, which is, as I understand, 2nd row in the total worksheet, but is actually 1st row in the range(A2:A999).
When I use this cellfound.Row value to refer to r_ptypes.cells(cellfound.Row), It is taking it as an Index value and returns B3 (P1-BQ900) instead of what I want, i.e. B2 (S1-RP003).
My question is how'll I find out the index number in cellfound? If not possible, how can I use Row number to extract data from r_ptypes?
Dante's solution above works fine. Also, I managed to get the index value using built in excel function Match instead of using Find method of a range. Listing it here for reference.
indexval = Application.WorksheetFunction.Match("searchvalue", r_products, 0)
Using the above, I'm now able to refer the rows in r_ptypes
skuvalue = r_ptypes.Rows(indexval).Value
Because .Row always returns the absolute row number of a sheet, not the offset (i.e. index) in the range.
So, just do some minus job to deal with it.
For you example,
r_ptypes.Cells(cellfound.Row - r_ptypes.Cells(1).Row + 1)
or a little bit neat (?)
With r_ptypes
.Cells(cellfound.Row - .Cells(1).Row + 1)
End With
That is, get the row difference between cellfound and the first cell and + 1 because Excel counts cells from 1.
