I am not sure what part is question and what part is code - can you clarify your question?

I can't figure out how to manipulate an array. I attached the excel file in my main post which contains the data for reference.

1. Worksheet 1: J2-Trading Journal

Content / Data from column T19 to T22 (Security Code, this will be the content of an array):

(dep.)

SMPH

HOUSE

HOUSE

ABC

etc. ...

2. Worksheet 2: TS-Traded Stocks

(Output data from J2-Trading Journal, to appear from C8, C9, C10, and so on...)

Data based on Worksheet #1:

ABC

HOUSE

SMPH

3.  Program specification

a. Collect the data from J2-Trading Journal worksheet under the "Security Code" table.

Here's the code I used to get them:

Dim vMyArrary() As Variant   

vMyArray = Sheets("J2-Trading Journal").Range("T19:T5000").Value

b. Array manipulation requirements:

-  Remove non-security code data (enclosed in parenthesis, e.g., (deposit), (subscribe), (etc.))

-  Remove the duplicate (data in array)

-  Sort the data within an array in ascending order.

-  The content of an array (vMyArray) should be manipulated first before updating the J2-Traded Stocks (is it possible?).

-  Then I will apply this code:

Sheets("TS-Traded Stocks").Range("C8:C5000").Value = vMyArray

4.  Program coding

Option Explicit

Sub RefreshTSData()

Dim vMyArray As Variant
Dim vNames As Range
Dim vCellData As Variant
Dim iCtr As Long

Set vNames = Sheets("J2-Trading Journal").Range("T19:T5000")

For Each vCellData In vNames

If Mid(vCellData.Value, 1, 1) = "(" Then

'do not add to array

Else

'validate: if duplicate value, do not add

'validate: if not duplicate, add to array
vMyArray(iCtr) = vCellData

End If

Next vCellData

Next iCtr

Sheets("TS-Traded Stocks").Range("C8:C5000").Value = vMyArray

'Debug.Print "No.", "Stock Code"
'For iCtr = 1 To 6   ''6= last row of non-empty cells
     'Debug.Print iCtr, vMyArray(iCtr)
'Next iCtr

End Sub

5.  Notes:

-  I am a newbie in programming and I would like to learn more, now on how to use and manipulate data in arrays

-  I would like to apply coding directly to my personal and actual database

The first thing I would say is don’t use Merged cells - they are the antichrist of excel and will only cause problems later on, if not now. You can use 'Centre Across Selection' instead which achieves the same visual results but doesn’t cause cell problems.

Personally I wouldn’t use arrays for this, I would copy column T and paste into a temporary worksheet, do the actions you want then copy it to where it is needed. Much simpler in my opinion and you can see the results as you step thru the code.

Got your point.

But my excel file is for distribution (once completed), the reason why I would like to automate things.

Plus, as I pointed out, to learn and practice coding purposes. At the same time applying those codes to my live data. I will start using this by January 2021.

Sorry my post wasnt clear - I agree that repeatable actions should be automated, i just dont use arrays like you have suggested.

It would be automated, use VBA to do all the steps mentioned but on a temp sheet. Then either hide or delete the sheet.

Something like this

Sub Temp()

Worksheets.Add.Name = "Temp"

Worksheets("J2-Trading Journal").Range("T19:t5000").Copy Worksheets("Temp").Range("a1")

Worksheets("Temp").Activate

Range("1:1").Rows.Insert

Range("a1") = "Stock"
Range("b1") = "Check"

Range("b2:b5000") = "=IF(A2="""","""",ISNUMBER(SEARCH(""("",A2)))"

Range("a:a").Sort key1:=Columns(1), order1:=xlAscending, Header:=xlYes

Range("1:1").AutoFilter field:=2, Criteria1:="false"

Range("a2:a5000").Copy Worksheets("TS-Traded Stocks").Range("c8")

Worksheets("TS-Traded Stocks").Activate

Application.DisplayAlerts = False

Worksheets("Temp").Delete

Application.DisplayAlerts = False

End Sub

Thanks a lot.
