VBA Excel Date Generator - vba

Question

I was wondering if there is a way using vba or excel to make an array of each day starting with Oct. 10th 2010 and ending with Sept. 30 2015. Unfortunately the dates have to be in the format YYYYMMDD, such as 20091001 and 20150930.
Thanks for the help

Answer 1

For a non-VBA solution KingsInnerSoul's solution is very good.
For VBA, you could do something like this:
Sub tgr()
Dim arrDates() As Variant
Dim dtStart As Date
Dim dtEnd As Date
'Assign start and end dates
dtStart = CDate("Oct 10, 2010")
dtEnd = CDate("Sep 30, 2015")
'Create the array by evaluating an Index formula
arrDates = Application.Transpose(Evaluate("INDEX(TEXT(""" & dtStart & """+ROW(1:" & dtEnd - dtStart + 1 & ")-1,""YYYYMMDD""),)"))
'Example of how to access the array values
MsgBox arrDates(1) & Chr(10) & _
arrDates(2) & Chr(10) & _
arrDates(3)
'You could iterate over the array with a loop also,
'or use any other array function, like Filter(), etc
End Sub

Create a list in Excel:
If you go to excel,
In the first top cell type 10/10/2010
Then right click on the cell - and select Format Cells,
Then go to the Custom category
In the Type input area type yyyymmdd - verify that it is the right format in the Sample field (I had it set to yyyymmdd;# )
Press OK
Once the cell is highlighted, you can see a border around it, and a + in the lower right corner of the cell.
Click on the + and drag it down as many rows as you need to - it will copy the cell's content and create a series with each cell adding a day.
Create a single row list in Word:
Once you created that single column in Excel, in the column next to it, type , (comma), and drag it down the same way in order to copy it next to the whole series.
Copy both columns in Excel.
Paste it to MS Word.
In the lower right corner an icon will appear - Paste Options.
Click on the Paste Options icon and select 'Keep Text Only' - It is the 'A' icon. Now you will have a single text column with the number, a tab character, comma, and Enter character.
Open the Search and Replace by pressing CTRL+H.
In the 'Find What' input field type ^p - it is the code for Enter.
Leave the `Replace With' field empty.
Press on `Replace All'.
Confirm the number of total replacements popup window by pressing OK.
To get rid of the Tab character, repeat steps 6-10 but search and replace ^w.
