Inserting a cell in excel based on cell value - mysql

I am working on exporting CSVs of large groups from an active directory environment. Many of these groups have extensive nesting and I need to insert cells so that the worksheet is human readable.
For example my worksheet looks like this:
WS Example
Int User Path
0 User1 CN
0 User2 CN
1 User3 CN
1 User4 CN
0 User5 CN
1 User6 CN
2 User7 CN
I am looking for help adapting a VBA script that reads the integer value from the first column and inserts the corresponding number of cells to the left of the column for that particular row. The constraint is that the list cannot change the order of the rows so as to preserve the nested structure.
Here is what I have in VBA so far
Sub test()
Dim d As Integer
d = Range("A:A").End(xlDown).row
Dim c As Range
For i = d To 1 Step -1
If Cells(i, 1).Value Like "1" Then
Rows(Cells(i, 1).Column).Insert shift:=xlShiftRight
End If
Next
End Sub
Currently this snippet counts the number of 1's from the column and inserts a new row at the top of the list. I believe the error in my logic is within the If statement and once I have that ironed out I know I can expand that with an ElseIf to address the rest of the values.

This will do it. The issue looks like it's within the line Rows(Cells(i, 1).Column).Insert shift:=xlShiftRight. If you break that down, it computes as follows:
Cells(i,1).Column which equals 1, since the column of .Cells(i,1) is 1.
Rows(1) the 1 comes from the above. So Rows(1) is 1.
Rows(1).Insert inserts above row 1, regardless of what you specify for shift.
Sub test()
Dim d As Integer
d = Range("A:A").End(xlDown).row
Dim c As Range
For i = d To 1 Step -1
If Cells(i, 1).Value Like "1" Then
Cells(i, 1).Insert shift:=xlToRight
End If
Next
End Sub

This should do it.
Sub test()
Dim d As Integer
d = Range("A:A").End(xlDown).Row
Dim c As Range
For i = d To 1 Step -1
aMove = Val(Cells(i, 1))
If aMove > 0 Then
Range(Cells(i, 1), Cells(i, aMove)).Insert shift:=xlToRight, CopyOrigin:=xlFormatFromLeftOrAbove
End If
Next
End Sub

Quite a few ways to do this, but by using the number in columnA to define the amount of cells to insert you can do a second loop like so:
Private Sub CommandButton1_Click()
Dim x, d, i As Integer
With ActiveSheet
d = .Range("A:A").End(xlDown).Row
For x = 2 To d
i = .Cells(x, 1).Value
For a = 1 To i
.Cells(x, 1).Insert Shift:=xlToRight, CopyOrigin:=xlFormatFromLeftOrAbove
Next a
Next x
End With
End Sub

What Discrete Optimization family is this?

I am given N lists of M items that will be physically realized (someone actually has to put items (names abbreviated here,) in physical bins.) Then the bins are emptied, if necessary, and re-used, working left-to-right. There is a real cost to putting a different item in a bin than what was in it before. I rearrange the lists to minimize changes, manually. Software can do it faster, and more reliably in an optimum way. The whole thing happens in Excel (then paper, then in a factory.) I wrote some VBA, a brute-force affair, that did really well with some examples. But not all. If I knew the family of optimization that this is, I could code it, even if I just pass something to a DLL. But multiple searches online have not succeeded. I tried several phrasings. It's not a traveling S.., knapsack, etc. It seems similar to the Sequence Alignment problem from Bioinformatics. Someone recognize it? Let's hear it, Operations Research people.
As it turns out, the naive solution just needed tweaking. Look at a cell. Try to find the same letter in the column to it's right. If you find one, swap it with whatever it to the right of that cell now. Work your way down. The ColumnsPer parameter accounts for the real-world use, where each column has an associated list of numbers and the grid columns alternate labels, numbers, labels, ...

How to delete a value from a dynamic array from any position in VBA?

I have a dynamic array that I want to delete an item from. I know we can delete an item from the end of an array by decreasing its size by 1 and redimming it. But is there a way to delete an item from an array no matter what position the item is on the array?
There is no built in function to delete from a array. So, the only way is to "pull" each value down by one, and then re-dim to lop off the last value.
Arrays hark back to old days of FORTAN and early GWBASIC languages that were popular on personal computers in the late 1970's, and early 80's. Most new languages (including VBA)) have a lot better choices. Because this is a "painful" approach, then I would build a function that deletes the row for you.
This code will show how deleting works:
Private Sub Command104_Click()
Dim MyData() As Integer
Dim i As Integer
ReDim MyData(1 To 5)
For i = 1 To 5
MyData(i) = i * 100
Next i
Call MyDisplay(MyData)
' delete 3rd row
Call MyDelete(MyData, 3)
Call MyDisplay(MyData)
End Sub
Public Sub MyDelete(v() As Integer, intPos As Integer)
Dim numRows As Integer
Dim i As Integer
numRows = UBound(v)
' move every row down one
For i = intPos To numRows - 1
v(i) = v(i + 1)
Next i
' get rid of last row
ReDim Preserve v(1 To numRows - 1)
End Sub
Public Sub MyDisplay(v() As Integer)
Dim i As Integer
For i = 1 To UBound(v)
Debug.Print i, "--->", v(i)
Next i
End Sub
Output:
1 ---> 100
2 ---> 200
3 ---> 300
4 ---> 400
5 ---> 500
1 ---> 100
2 ---> 200
3 ---> 400
4 ---> 500

Is there an excel function to duplicate rows based on a range of numbers in a cell?

I am trying to do an import into a database and each product variation has to be line by line. Unfortunately the person who set this up, one of the cells has a range of say for example 1-50. I was wondering if there was some way to duplicate the rows with the exact information, except replacing the cell with 1, then a new row with 2, etc all the way to 50.
I don't know if there is a function to do that but, you can use excel macros to solve your problem.
I tried with a simple example:
Assume your excel file format is
Name Range
A 3
B 5
After you run VBA script it becomes
Name Range
A 1
A 2
A 3
B 1
B 2
B 3
B 4
B 5
I changed the code with "bottom to top" version because it's a better solution
Private Sub InsertBottomToTop()
Dim i, cursor As Integer
cursor = 5 '# of rows you have initially (including header)'
For cursor = 5 To 2 Step -1
For i = 0 To Cells(cursor, 2) - 2
Cells(cursor, 1).EntireRow.Copy
Range("A" & Cells(cursor, 1).Row + 1).Insert Shift:=xlDown
Application.CutCopyMode = False
Cells(cursor, 2).Value = Cells(cursor, 2).Value - 1
Next i
Next cursor
End Sub

how to import 2 row from txt or EXCEL into the same ROW in SQL server

I need to extract information from a page I have access to.
Just in this module, I have no means to export, but just to copying and pasting the information
Looks like this in the same l
1. MANUF MODEL YEAR MFG SERIAL REG OS DATE DESC LISTED1. YEAR DLV
2. monster 4r25 1988 23547248 Waka001 7/23/2012 For sale 7/22/20092. 1989
3. FORD 12SE 1994 6262552 DBZRLZ0 7/26/2012 For sale 7/9/20093. 1994
I'm getting my data in rows, but the year mfg and year dlv is in 2 rows within one row (or 2 rows in the same field). When pasted on excel it makes 2 rows first with all the data in the row including year mng and a second row just for year dlv (in the same column).
I can parse this information in excel by adding extra column and coping that extra field and deleting blanks and so on. But I want to omit the excel part and import this from a TXT file which when pasted creates 2 rows per row as well and using tabs as delimiter (like txt text tab delimited).
When I import with bulk insert, it imports twice as much rows, but I can't imagine a way to parse this second row into a new column.
Can someone help with this? In t-sql (every row has only one row of info, but in the column year mfg /year dlv, comes with two rows).
Or point me on what to read or which would be a better approach? Maybe importing 2 rows at once ETC.
You can import the data set from the text file into a temp table including the blank lines. This will give you a data set in SQL with 2 types of records. 1. Records that have all data except delivery date. 2. Records that have only delivery dates and no other fields. (Add a unique auto increment key)
Because the related records will be one record apart, Record N and Records N+1 are actually the same record.
Then a select query Joining the temp table to its self by RecID = RecId+1 will give a complete record with all fields
SELECT * FROM tmpTable AS MainRecord INNER JOIN tmpTable AS MissingField ON MainRecord.RecId = MissingField.RecId +1
From this dataset you can instert into your main data.
Do you know how to use VBA? You can run this code (FixData()) in Excel before you use it in TSQL so it fixes the extra row problem. Hope this helps
Option Explicit
Public Sub FixData()
Dim ws As Excel.Worksheet
Dim iCurRow As Long

Set ws = ActiveSheet
iLastRow = ws.Cells.SpecialCells(xlCellTypeLastCell).Row
' move through the spreadsheet from bottom to top

If (cellCountInRow <= 1) Then
isCurrentRowMessedUp = True
Else
isCurrentRowMessedUp = False
End If

Excel Macro to concatenate multiple rows from Column B per ID rows in Column A with newlines

This problem is in an Excel .xls file.
Simplest Use Case:
Column A has one row.
Column B has 5 rows.
The 5 rows in Column B need to be merged into one row, delimited by newlines.
I have a huge .xls document where there are a ton of IDs in column A.
There are on average anywhere from 3 to 10 rows that belong to each column A row.
How to know which Column B rows belong to which Column A?
By the positioning of the cells.
One Column A row may have 5 Column B rows to the right of it.
I don't have any VBA experience.
I have looked around for macros and functions but haven't had any luck finding anything that matches this problem.
Edit:
I am now trying to figure out how to get the script to ignore rows that have a one-to-one mapping between column A and column B.
Edit again - 06-20-2012:
Now that I can attach images, here is a screenshot of an image for what I'm trying to get.
The rows for Brian and Mark should be ignored, while Scott and Tim get their values copied over.
Edit:
Unmerging column A, using the code that Andy supplied, and then using this VB script afterwards does the trick:
Sub mergeA()
For i = 2 To Cells(65535, 1).End(xlUp).Row
If IsEmpty(Cells(i, 1)) Then Range(Cells(i - 1, 1), Cells(i, 1)).Merge
Next
End Sub
That VB script puts the cells in column A back together
I didn't make the script, it came from this web page:
