I have data that has been stacked prior to my receiving it. There are multiple rows of values for a single unifying ID. I'd like to convert those multiple rows into a single row by adding columns and pulling in a specified range of data. So my initial data looks like:
[TABLE="width: 345"]
<tbody>[TR]
[TD]ID[/TD]
[TD]Name[/TD]
[TD]Subject[/TD]
[TD]Date[/TD]
[TD]Code[/TD]
[/TR]
[TR]
[TD]1[/TD]
[TD]Bob[/TD]
[TD]Golf[/TD]
[TD]1-Mar[/TD]
[TD]xyz[/TD]
[/TR]
[TR]
[TD]2[/TD]
[TD]Adam[/TD]
[TD]Cards[/TD]
[TD]2-Mar[/TD]
[TD]xcv[/TD]
[/TR]
[TR]
[TD]2[/TD]
[TD]Joe[/TD]
[TD]Cards[/TD]
[TD]5-Mar[/TD]
[TD]xch[/TD]
[/TR]
[TR]
[TD]3[/TD]
[TD]Will[/TD]
[TD]Travel[/TD]
[TD]6-Mar[/TD]
[TD]vvv[/TD]
[/TR]
[TR]
[TD]3[/TD]
[TD]Bill[/TD]
[TD]Travel[/TD]
[TD]1-Mar[/TD]
[TD]crt[/TD]
[/TR]
[TR]
[TD]3[/TD]
[TD]Thrill[/TD]
[TD]Travel[/TD]
[TD]2-Mar[/TD]
[TD]abt[/TD]
[/TR]
[TR]
[TD]4[/TD]
[TD]Napoleon[/TD]
[TD]Grapeshot[/TD]
[TD]3-Mar[/TD]
[TD]xso[/TD]
[/TR]
</tbody>[/TABLE]

And my output data should look like:
[TABLE="width: 601"]
<tbody>[TR]
[TD]ID[/TD]
[TD]Name[/TD]
[TD]Subject[/TD]
[TD]Date[/TD]
[TD]Code[/TD]
[TD]Column1[/TD]
[TD]Column2[/TD]
[TD]Column3[/TD]
[TD]Column4[/TD]
[/TR]
[TR]
[TD]1[/TD]
[TD]Bob[/TD]
[TD]Golf[/TD]
[TD]1-Mar[/TD]
[TD]xyz[/TD]
[TD][/TD]
[TD][/TD]
[TD][/TD]
[TD][/TD]
[/TR]
[TR]
[TD]2[/TD]
[TD]Adam[/TD]
[TD]Cards[/TD]
[TD]2-Mar[/TD]
[TD]xcv[/TD]
[TD]Joe[/TD]
[TD]Cards[/TD]
[TD][/TD]
[TD][/TD]
[/TR]
[TR]
[TD]3[/TD]
[TD]Will[/TD]
[TD]Travel[/TD]
[TD]6-Mar[/TD]
[TD]vvv[/TD]
[TD]Bill[/TD]
[TD]Travel[/TD]
[TD]Thrill[/TD]
[TD]Travel[/TD]
[/TR]
[TR]
[TD]4[/TD]
[TD]Napoleon[/TD]
[TD]Grapeshot[/TD]
[TD]3-Mar[/TD]
[TD]xso[/TD]
[TD][/TD]
[TD][/TD]
[TD][/TD]
[TD][/TD]
[/TR]
</tbody>[/TABLE]

Ideally, I'd like to see the macro two ways- in this case, it's pulling from a range of columns that are together (B:C). However, I'd also like to see it if the columns needed were not consecutive (B and E for example).
Thanks for any help, appreciate it!!

Convert text numbers to real numbers
Select a column containing text numbers. Press Alt+D E F to quickly convert text to numbers. Faster than "Convert to Number"
I'm dashing to go out so I can't write you any VBA at the moment but... can this be done with a pivot table?

Thanks for your reply. A standard pivot table cannot display text values, which my columns typically are. In my research, I saw that Get and Transform (aka PowerQuery) might be able to make a semblance of this. However, for a data set of any size (even 100 rows), I couldn't get this result- not even close really. If you have a method to do it manually as a process, that would certainly be welcome as well. I can get there using IF formulas, but in the very possible scenario that there may be 20+ rows tied to the same ID, and I need to pull 7 columns for each row, it takes a fair bit of time to adjust the formulas in every new column. More importantly is avoiding the potential for manual error as well. Thanks!

In case anyone else runs into this issue, wanted to post the code I ended up using (disclaimer: got some help to get it done)

Code:
[FONT=Calibri]Sub UnstackData()[/FONT][FONT=Calibri]  Dim wSht1 As Worksheet, wSht2 As Worksheet[/FONT]
[FONT=Calibri]  Set wSht1 = Sheets("Sheet1")[/FONT]
[FONT=Calibri]  Set wSht2 = Sheets("Sheet2")[/FONT]

[FONT=Calibri]  Dim r As Integer: r = 2[/FONT]
[FONT=Calibri]  Dim r2 As Integer: r2 = 1[/FONT]
[FONT=Calibri]  Dim r1 As Integer, c2 As Integer[/FONT]

[FONT=Calibri]  With wSht1[/FONT]
[FONT=Calibri]    wSht2.Rows(1).Value = .Rows(1).Value[/FONT]
[FONT=Calibri]    r1 = .Cells(.Rows.Count,"A").End(xlUp).Row[/FONT]

[FONT=Calibri]    Do While r <= r1[/FONT]
[FONT=Calibri]      c2 = 16 [/FONT]

[FONT=Calibri]      Do While .Cells(r, "A") =.Cells(r - 1, "A")[/FONT]
[FONT=Calibri]        wSht2.Cells(r2, c2).Value = .Cells(r,"B").Value[/FONT]
[FONT=Calibri]        wSht2.Cells(r2, c2 + 1).Value =.Cells(r, "C").Value[/FONT]
[FONT=Calibri]        c2 = c2 + 2[/FONT]
[FONT=Calibri]        r = r + 1[/FONT]
[FONT=Calibri]      Loop[/FONT]
[FONT=Calibri]      r2 = r2 + 1[/FONT]

[FONT=Calibri]      Do While .Cells(r, "A")<> .Cells(r - 1, "A")[/FONT]
[FONT=Calibri]        wSht2.Range("A" & r2& ":E" & r2).Value = .Range("A" & r &":E" & r).Value[/FONT]
[FONT=Calibri]        r = r + 1[/FONT]
[FONT=Calibri]        r2 = r2 + 1[/FONT]
[FONT=Calibri]      Loop[/FONT]
[FONT=Calibri]      r2 = r2 - 1[/FONT]

[FONT=Calibri]    Loop[/FONT]

[FONT=Calibri]  End With[/FONT]

[FONT=Calibri]End Sub[/FONT]
