How to convert a long form table to wide form table in Excel?

Question

A picture is worth a thousand words. Let\'s say in one sheet I have the following table:

Answer 1

Using VBA:

Range("G1:K99").Clear
For Each xx In Range("A:A")
    If xx.Value = "" Then Exit Sub
    Range("G1").Offset(xx.Value, 0) = xx.Value
    For e = 1 To 99
        If Range("G1").Offset(xx.Value, e) = "" Then
            Range("G1").Offset(xx.Value, e) = xx.Offset(0, 1).Value
            Exit For
        End If
    Next
Next

The table it's created from column "G". If you want another sheet:

Sheets(2).Range("G1: ...

add the Sheets before ...

Without VBA, following the scheme:

Adding the formulas:

M2 -> =IFERROR(MATCH(L2;$A$1:$A$8;);"")
N2 -> =IFERROR(MATCH(L2;INDIRECT("$A" & (M2+1) & ":$A$8");)+M2;"")
O2 -> =IFERROR(MATCH(L2;INDIRECT("$A" & (N2+1) & ":$A$8");)+N2;"")
P2 -> =IFERROR(INDEX($B$1:$B$8;M2);"")          Autocomplete also columns to R

and Autocomplete ...

Answer 2

I can see another approach as well. Add two columns Count and Key.

Add the formulas and expand:

C2 -> =COUNTIF($B$2:B2;B2)
D2 -> =B2&"|"&C2
G2 -> =IFERROR(INDEX($A:$A;MATCH($F2&"|"&COLUMN(A1);$D:$D;0));"")
