[RESOLVED] Excel 2003 - Get certain column from all XLS in a directory

Hi all,

Excuse my completely newbie question but I have virtually no experience with programming Excel. What I'm trying to do is grab addresses from a certain column on a certain sheet from many Excel files in a directory

So my task is:
-Loop through all Excel files in a certain directory.
-Grab the values of cells in a certain column (they are all in the same column) up to a point.
--This would be everything in between the first non-blank cell and the next non-blank cell inclusive: 3-5 lines worth.
--There are no headers. It is an invoice-like sheet.
-Place each value in a specific column in a new workbook.

If I can provide further information just let me know.

Frankly, I don't know where to start. Any push in the right direction is certainly appreciated. Somebody kick this new Excel programmer in the head. :bigyello:

1. Build a list of file names (using file functions which I have not used in years).
2. Load an instance of Excel Dim XL as New Excel.Application
3. Xl.Open to all of your files in your list, make sure that you tell Excel to not ask you if you want to update linked data etc or that will throw you off. It is a property for the XL object.
4. Open a new workbook, set its reference Set Wkb = Xl.Workbooks("thisisme")
5. Cycle through the workbooks
For I = 1 to Xl.Workbooks.Count Then
'select the correct sheet
'test workbook name to make sure your not ripping data from your composite data sheet
'cycle through the rows until your done (test for empty/null)
AddData "Data Ripped from other sheet"
Next I
6. Save your new workbook
7. Close all workbooks

Thats the gist of it. I can elaborate. As I have coded what your looking for except for the building a list of file names from a directory part.

Heres what I have done. Not perfectly matched to what you want.

Thanks for the quick reply! I'm going to digest this and I'm sure I'll be back with some questions.

So here is what I ended up doing. This is probably ugly and I'm certain many improvements can be made but until I get a chance to play around with the Excel object a bit more, this will do.

The one question I did have is why can't I get to the cell's Value, Text or any properties for that matter when I use Cell(1,1) however I can when I use Range("A1")?

Thanks again for the push in the right direction. :thumb:

Yours is far more nice to look at then mine haha :)

So your saying your fromSheet.Cells(firstData + 4, 3) returns nothing though there should be a value?

The reason you get more options I am guestimating from the Range, is simply the object model support. The Cells references is probably a quick and dirty, and the Range exposes all properties. My thoughts.

It does return a value and the code works as expected.
I'm saying that I had to do this

vb.net Code:

Do Until fromSheet.Range("C" & firstData).Text.ToString().Trim().Length > 0

because this

vb.net Code:

Do Until fromSheet.Cells(firstData, 3).Text.ToString().Trim().Length > 0

doesn't work. I can't get to any of the cells properties using Cells in place of Range.

Just curious. :)

Shouldn't it be "Do While" instead of "Do Until"?

I probably would of did..

Do While Len(Trim((sht.Cells(3,3))))>0

It's "Until" for my purpose. I was looking in the column for the first cell that had something in it. I was trying to get a reference to the first cell that contained some data.
