VBA Grid Generation with User Input - excel

The aim of this code is to have the user input that they want an, e.g. 4x10 grid. I have attached a photo below of the desired output.
However, I'm stuck on the logic of the problem. I can generate one set of grid numbers (e.g. 1-25), but unsure how to duplicate this process to create the whole grid.
Hard to explain using words....
In short I am aiming for:
A1, A2, A3, A4, B1, B2, B3, B4 ...
But I am currently getting: A1, B2, C3, D4 ...
Tried experimenting with different code but to no success. Current code has a loop that I think is right in principle, but re-writes the data in the rows above it once it finishes one 'j' loop and goes back to the start. I'm not sure how to get 'j' to start on a blank cell rather than overwrite what is already in it.
['Userform prior to this step gathers user input
Dim Axial_Data_Points As Variant
Dim Circum_Data_Points As Variant
Axial_Data_Points = Axial_Data_Points_Box.Value 'User input value
Circum_Data_Points = Circum_Data_Points_Box.Value 'User input value
'Basic loop to generate a list of numbers up to the user imposed limit
For j = 1 To Axial_Data_Points
Worksheets("Data Entry").Activate
For k = 1 To Circum_Data_Points
Range("E" & ((j + k) + 1)).Select
ActiveCell.FormulaR1C1 = j
Next k
Next j]
1

This will produce output like:
Dim Axial_Data_Points As Variant
Dim Circum_Data_Points As Variant
Axial_Data_Points = Axial_Data_Points_Box.Value 'User input value
Circum_Data_Points = Circum_Data_Points_Box.Value 'User input value
'Basic loop to generate a list of numbers up to the user imposed limit
Dim i As Integer
Dim j As Integer
For i = 1 To Axial_Data_Points
For j = 1 To Circum_Data_Points
Worksheets("Data Entry").Cells(j + (i - 1) * 10, 4).Value = Chr(i + 64)
Worksheets("Data Entry").Cells(j + (i - 1) * 10, 5).Value = j
Next j
Next i
End Sub
Using Something of this type you can generate what you require:
j = 1
k = 1
For i = 1 To 200
If j < 27 Then
Range("A" & i).Value = Chr(j + 64)
j = j + 1
ElseIf j > 26 And j < 53 Then
G:
Range("A" & i).Value = Chr(k + 64) & Chr(j - 26 + 64)
j = j + 1
Else
j = 27
k = k + 1
GoTo G
End If
Next
You will have to put it in your code.

VBA Randomize values from 1 to 30 thereby skipping manually entered values

For the first 15 ranks, I want to manually enter the values in B2:P11. For ranks 16 to 30, I want to randomize these values using an Excel VBA button, with the following code:
Sub rand_group()
Dim i As Long
Dim j As Long
Dim myFlag(1 To num_man)
Dim s_group As Worksheet
Set s_group = Worksheets("group")
'óêêîånóÒÇèâä˙âª
Randomize
s_group.Cells.Clear
s_group.Range("A1") = "group_id"
For i = 1 To num_group
s_group.Cells(i + 1, 1) = i
Next i
For i = 1 To num_man
s_group.Cells(1, i + 1) = "m_rank" & i
Next i
For i = 1 To num_group
For j = 16 To num_man
myFlag(j) = False
Next j
For j = 16 To num_man
Do
'óêêî=Int((ç≈ëÂíl - ç≈è¨íl +1 ) * Rnd + ç≈è¨íl)
myNum = Int((num_man - 1 + 1) * Rnd + 1)
Loop Until myFlag(myNum) = False
s_group.Cells(i + 1, j + 1).Value = myNum
myFlag(myNum) = True
Next j
Next i
End Sub
However, these random values should neglect the manually entered values in B2:P11
How can I change the code to fix this?
Screenshot of the excel file is displayed below:
I want to manually fill values from B2 to P11
Thank you in advance for your response!

To fill in the random section of the grid, the myFlag array is not needed. Just use the cell coordinates to set the random values. Also remove the Clear call since that clears the entire sheet.
To prevent duplicate numbers in a row, use the excel CountIf function in a loop until a unique random number is found.
Here is the updated code. It can be run multiple times without affecting the manual data.
Sub DoRand()
Dim i As Long
Dim j As Long
Dim s_group As Worksheet
Set s_group = Worksheets("group")
num_group = 10
num_man = 30
Randomize
's_group.Cells.Clear ' clear sheet
' build table
For i = 1 To num_group ' group id
s_group.Cells(i + 1, 1) = i
Next i
For i = 1 To num_man ' column names
s_group.Cells(1, i + 1) = "m_rank" & i
Next i
' fill in random numbers
For i = 1 To num_group 'row
For j = 16 To num_man 'column
Do While True
n = Int((num_man) * Rnd + 1) ' get random number
cnt = Application.WorksheetFunction.CountIf(Range(s_group.Cells(i + 1, 2), s_group.Cells(i + 1, j)), "=" & n) ' check if number in row
s_group.Cells(i + 1, j + 1).Value = n ' set cell value
If cnt = 0 Then Exit Do ' if unique in row, go to next cell
Loop ' not unique, try new random value
Next
Next
End Sub

Update Column Range with the cell value

I have an input sheet called "Testfall-Input-Vorschlag where we have to choose a value from a dropdown in the cells of the first row from the 7th (J)column and when a value gets chosen for example "ARB13" I want to fill out the column where it is selected. The filling of the column is with random values. There is a Sheet called "Admin" which has values stored in the cells of columns from A:ZZ. Now I in the "Testfall-Input-Vorschlag" sheet I want to fill out the cells of the column sequentially. Which means for example for cell(11,7) i want to generate a random value from column A in "Admin" for cell (12,7) the value has to be from Column B in "Admin" for cell (13,7) the value is from column C in "Admin and so on. So I have been trying and I've come up with this code
Sub ARB13()
Dim col As Integer
For i = 11 To 382
For j = 7 To 1000
If Sheets("Testfall-Input_Vorschlag").Cells(1, j) = "ARB13" Then
col = 0
col = col + 1
LB = 2
UB = Sheets("Admin").Range("col" & Rows.Count).End(xlUp).Row
Cells(i, j).Select
ActiveCell.FormulaR1C1 = Sheets("Admin").Range("Y" & Int((UB - LB + 1) * Rnd + LB))
End If
Next j
Next i
End Sub
How can I update the col value for every i. Which means for every i I need col value to be increased by 1. Where am I going wrong?
Define col before you start your first loop, and don't put col = col + 1 in the For j = 7 to 1000 loop. Otherwise col will increment for every j instead of every i. Something like this:
Sub ARB13()
Dim col as Long
Dim i as Long
Dim j as Long
col = 0
For i = 11 To 382
For j = 7 to 1000
LB = 2
UB = Sheets("Admin").Cells(Rows.count, col).End(xlUp).row
Cells(i, j).Select
ActiveCell.FormulaR1C1 = Sheets("Admin").Range("Y" & Int((UB - LB + 1) * Rnd + LB))
Next j
col = col +1
Next i
End Sub

Generation of sequential serial number based on prefix value

We have prefix defined already (say ABC, GIJ, THK, JLK ...so on) and want to create a sequential number when a user wants to generate a number for each of these prefix like given below:
ABC0000 , ABC0001 , ABC0002 ...ABC9999 same for GIJ0000 , GIJ0001 , GIJ0002 ...GIJ9999.
Given below is the code written for the above logic, but it does not achieve the requirement:
Private Sub CommandButton1_Click()
With ComboBox1.Value
Dim a, b As String
Dim i, j, k, l, x, q, m, temp As Long
a = ComboBox1.Text
i = Application.WorksheetFunction.Match(a, Range("A1:A1000"), 0)
j = Cells(i, 2)
l = j * 1000
For q = 2 To 100
For m = 2 To 100
If Cells(q, m).Value < 0 Then
k = m
End If
Next
Next
x = l
If Cells(i, GC).Value = temp Then
click = click + 1
Else
click = 0
End If*
Cells(i, GC) = x + click
TextBox1.Text = x + click
temp = Cells(i, GC).Value
End With
GC = GC + 1
End Sub
VBA does not seem necessary for this. Assuming you have your prefixes in separate cells in ColumnA starting in Row1, put in B1:
=A1&TEXT(COUNTIF(A$1:A1,A1)-1,"0000")
and double-click its fill handle.
From your code, I assume that you have a ComboBox named ComboBox1, a CommandButton named CommandButton1 and a TextBox named TextBox1, all on a UserForm, and with ComboBox1 filled with the possible values for prefixes.
The following code will put the next available code(1) for the selected prefix into the TextBox.
Private Sub CommandButton1_Click()
Dim a As String
Dim i As Long, j As Long
a = ComboBox1.Text
i = Application.WorksheetFunction.Match(a & "9999", Range("A1:A1000"), 1)
j = CLng(Mid$(Cells(i, 1).Value, Len(a) + 1)) + 1
TextBox1.Text = a & Format(j, "0000")
End Sub
Your code is also doing a lot of unnecessary stuff.

Multiple array assignment to an excel range

Just out of curiosity ,I am asking you a question which is as below:
Suppose i do have an array A1(6)=(45,25,,36,88),A2(6)=(14,25,11),A3(6)=(11,21,20,25,48).Now can we put those array values with the help of a single statement like single array assignment to a row,as here all the rows to a range of an Excel, Say here "C1:R3" range.
EDIT
If I need to assign them to a row like R1<- A1 + A2 +A3,R2<- A1 + A2 +A3. Can you tell me how to this?
R1<- (45,25,,36,88),14,25,11,,,,11,21,20,25,48,) same for R2.
Thanks,
Dim A(2,5)
For i = 0 to 5
A(0, i) = A1(i)
A(1, i) = A2(i)
A(2, i) = A3(i)
Next i
Range("C1:R3").Value = A
EDIT
For second part, to the best of my understanding:
Dim R(17)
For i = 0 To 2
For j = 0 To 5
R(6 * i + j) = A(i, j)
Next j
Next i
Range("C5:T5").Value = R
EDIT 2
Alternatively:
Dim R
R = Split(Join(A1, ",") & "," & Join(A2, ",") & "," & Join(A3, ","), ",")
Range("C5:T5").Value = R
You can use any delimiter you like (if it's appropriate for your data).

VBA-Excel and large data sets causes program to crash

First time poster and new to programming in general. I have a project in which i have to build a financial model to mine for data in excel. I have succeeded in building said model on VBA. I have ran tests on 3,000 line dataset and it was successful. I will briefly explain what it does.
I track a given stock on a given day on multiple exchanges. I download the data (roughly 935,000 lines) The first step is copy all the data for a given exchange (roughly 290,000) onto a new sheet (this takes roughly 8min), then I create a new column to log the bid ask spread (12secs), the next step is what Im having trouble with, I basically rank each line of data twice, one column for Bid size and one column for Ask size. I created a function which uses excel Percentile function and ranks based on where the given bid and ask size lands. As of right now, I have been running the Macro for the last 35min and has yet to execute. I cant attempt the other macros since each macro depends on the previous one.
So my basic issue is that since my data set is large, my model keeps crashing.The code seems to be fine when working with the test data, and it doesn't throw any errors when I run the program, but with the larger data set it just crashes. Does anyone have any suggestions? Is this normal with such large amounts of data?
Thanks in advance.

Here is the sub and function thats giving me the trouble, the sub takes in the required inputs to run the function and then pops into the assigned cell.

935,000 lines is a lot for excel. Like, really a lot. Barring saying using a real database, If your application is literally putting a =Percentile(...) in each cell, I would recommend Trying to use another tool for that. Perhaps something within VBA itself. More generally, use something outside of a cell - then store the result value in the cell. There is a lot of overhead in maintaining those formulas that are interdependent on 935k rows of data.
The problem is that your looping through each row individually, the Excel way is to try and work with whole ranges at once whenever possible. I would load the ranges into arrays, then modify your DECILE_RANK code to work with the items in the array.
Note that variant arrays that read ranges in are 2-D.
Here is the fully functioning code including my custom VBA array slicer. Note that it was only tested on a small dataset:
