Concat tables in different excel worksheet - vba

Question

Question
I'm trying to do something that may be very simple using Excel but I can't find how to do it.
I have several worksheets, each one contains a single table. To give you an example, here are two of my worksheets :
First worksheet. Please note that lines are green.
Some data. Without 's', sorry :-)
Second one. Lines are grey but cells can be red. Headers are NOT the same
I would like to :
merge those tables into another worksheet
keep style formatting (line color, etc)
when I update a table, the merged one should update too (may be a macro)
Here is a possible output :
Note that same headers are correctly merged.
Can I do this with Excel ? I know that I can do a query (UNION ALL) but doing this doesn't preserve style formatting.
Edit 1
I've tried to build the table using microsoft queries. Here is my query :
SELECT * FROM `C:\Users\cflodrops\Downloads\comptes.xlsx`.`Purchases$` `Purchases$`
UNION ALL
SELECT * FROM `C:\Users\cflodrops\Downloads\comptes.xlsx`.`Sales$` `Sales$`
UNION ALL
SELECT * FROM `C:\Users\cflodrops\Downloads\comptes.xlsx`.`Trades$` `Trades$`
UNION ALL
SELECT * FROM `C:\Users\cflodrops\Downloads\comptes.xlsx`.`Transfers$` `Transfers$`
This request works great, here is the result :
But I still have issues :
style formatting is incorrect (background colors and numbers format)
datas are not synchronized between arrays. It's not an issue, I can create a macro to execute the request whenever I click on a button.

Answer 1

you have a few problems...union can work. Assuming union path from your first edit.
Add placeholder columns on both sheets to allow proper union, OR force placeholders columns in with your t-sql queries.
Add columns to each sheet representing the source OR add these in with your t-sql queries. e.g. 'Sheet1'
On your unioned sheet with the results, add conditional formatting, where the row with the cell of the source type is evaluated, then the entire row is formatted as necessary. e.g. cell A2 has 'Sheet1', then row A is colored green.

Answer 2

If i understand you well, you want to:
copy data preserving formatting from existing sheets and put them into another sheet (new or existing; let's call it "merged data"),
keep one-way synchronization betweem source sheets and "merged sheet", which means when source sheet is changing, a "merged sheet" changes too.
The answer for both issues is YES depending on a way you choose to merge/synchronize/display data...
Method #1 - using copy & paste data one below another
This method will preserve formatting, but there's no chance to update destination table (sheet) when source data have been changed. You'll need to create it every time you want to see merged data.
Method #2 - using Range.CopyFromRecordset method together with UNION statement
If you want to use this method, you have to change your data set into model of relational database. There's no chance for preserving source formatting, but "merged sheet" may be quickly reloaded (a'ka updated).
Both methods of copying data between sheets you'll find here: Copy Data Between Excel Sheets using VBA, but this tip does not provide information about copying data within its originall format. So, i decided to clarify how to achieve that and show/provide code which create destination sheet with merged data.
In my example i have 3 sheets. First and second sheet is used as source of data and the 3. one is used to display merged data. Only 3 columns (A-C) contain data, so ranges to copy are hard-coded.
Option Explicit
'method #1
Private Sub CopyWithFormatting(srcSh As Worksheet, dstSh As Worksheet, Optional sCol As String = "A")
Dim e1 As Long, e2 As Long
On Error GoTo Err_CopyWithFormatting
'last row in src and dst sheet
e1 = srcSh.Range(sCol & srcSh.Rows.Count - 1).End(xlUp).Row
e2 = dstSh.Range(sCol & dstSh.Rows.Count - 1).End(xlUp).Row + 1
'do not refresh screen
Application.ScreenUpdating = False
'copy defined range
srcSh.Range("A2:C" & e1).Copy
'paste below existing data
With dstSh.Range("A" & e2)
.PasteSpecial xlPasteAllUsingSourceTheme
.PasteSpecial xlPasteFormats
.PasteSpecial xlPasteValidation
End With
Exit_CopyWithFormatting:
On Error Resume Next
'restore default settings
With Application
.CutCopyMode = False
.ScreenUpdating = True
End With
Exit Sub
Err_CopyWithFormatting:
MsgBox Err.Description, vbExclamation, "Err no. " & Err.Number
Resume Exit_CopyWithFormatting
End Sub
How to use it?
Sub TestMethod1()
Dim CopiedSheet As Worksheet, DestSheet As Worksheet
'as i mentioned -> 3. sheet is used to merge data
'you can change it by using sheet's name or its index
Set DestSheet = ThisWorkbook.Worksheets(3)
'copy data from sheets into destination sheet
For Each CopiedSheet In ThisWorkbook.Worksheets
'ignore destination sheet
If CopiedSheet Is DestSheet Then GoTo SkipNext
CopyWithFormatting CopiedSheet, DestSheet
SkipNext:
Next
End Sub
Finall note: Feel free to change above code to your needs.

Answer 3

In the third sheet I would have a macro in the Activate event, that pulls the data from from the first two sheets. I would add a hidden column in the third sheet that contains to originating sheet. In your conditional formatting for the third sheet you would need to base your formatting on the value in the hidden column. I can post a sample to clarify if you wish.
EDIT: Added sample
Private Sub Worksheet_Activate()
Application.ScreenUpdating = False
Application.Calculation = xlCalculationManual
Dim Sheet1 As Worksheet
Dim Sheet2 As Worksheet
Dim Sheet3 As Worksheet
Set Sheet1 = Worksheets(1)
Set Sheet2 = Worksheets(2)
Set Sheet3 = Worksheets(3)
Sheet1.Range("A2:D101").Copy
Sheet3.Cells(2, 1).Select
Selection.PasteSpecial Paste:=xlPasteValues, Operation:=xlNone, SkipBlanks:=False, Transpose:=False
Sheet2.Range("A2:D101").Copy
Sheet3.Cells(102, 1).Select
Selection.PasteSpecial Paste:=xlPasteValues, Operation:=xlNone, SkipBlanks:=False, Transpose:=False
Sheet3.Cells(1, 1).Select
ActiveWorkbook.Worksheets("Sheet3").AutoFilter.Sort.SortFields.Clear
ActiveWorkbook.Worksheets("Sheet3").AutoFilter.Sort.SortFields.Add Key:=Range _
("A1:A201"), SortOn:=xlSortOnValues, Order:=xlAscending, DataOption:= _
xlSortNormal
With ActiveWorkbook.Worksheets("Sheet3").AutoFilter.Sort
.Header = xlYes
.MatchCase = False
.Orientation = xlTopToBottom
.SortMethod = xlPinYin
.Apply
End With
Application.ScreenUpdating = True
Application.Calculation = xlCalculationAutomatic
End Sub
