我正在使用以下資料集。對于每家公司，我想了解他們訂購了多少種不同的產品。
例如：公司“AAA”訂購了 6 種不同的產品（產品 1、2、3、4、5、7）。
不確定，如果我們需要在每列中拆分單詞，然后在回圈中一一計數，或者有什么更快的方法？這里必須使用VBA，我的資料集超過100k。

假設資料在A1:C?：
Sub Test()
Dim arr As Variant
Dim lr As Long, x As Long, y As Long
Dim dict1 As Object: Set dict1 = CreateObject("Scripting.Dictionary")
Dim dict2 As Object: Set dict2 = CreateObject("Scripting.Dictionary")
'Get initial array (NOTE: implicit reference to the active worksheet)
lr = Cells(Rows.Count, "A").End(xlUp).Row
arr = Range("A2:C" & lr)
'Loop through array and fill dictionary
For x = LBound(arr) To UBound(arr)
dict1(arr(x, 1)) = dict1(arr(x, 1)) & "," & arr(x, 3)
Next
'Loop through dictionary and count unique items
For y = 0 To dict1.Count - 1
For Each el In Split(dict1.Items()(y), ",")
dict2(el) = 1
Next
dict1(dict1.keys()(y)) = dict2.Count - 1
dict2.RemoveAll
'Check the result
Debug.Print dict1.keys()(y) & "-" & dict1.Items()(y)
Next
End sub

這個答案可能看起來很愚蠢，但是當您用逗號分隔不同的產品時，為什么不簡單地計算逗號的數量并加 1，例如：
=SEARCH(",",C2,1) 1
一旦在輔助列中包含此資訊，您就可以使用 Excel 的基本Subtotals功能來查找每位客戶的總和。

請測驗下一個代碼。它將回傳（在下一個作業表中的上述代碼中，但它可以在任何作業表中回傳）唯一客戶，然后是產品總數，在下一列中是訂購的產品：
Sub ProductsPerClient()
Dim sh As Worksheet, sh1 As Worksheet, lastR As Long, arr, arrSpl, arrFin, colMax As Long
Dim i As Long, j As Long, dict As Object
Set sh = ActiveSheet
Set sh1 = sh.Next 'use here the sheet you need
lastR = sh.Range("A" & sh.rows.count).End(xlUp).row
arr = sh.Range("A2:C" & lastR).value
Set dict = CreateObject("Scripting.Dictionary")
For i = 1 To UBound(arr)
arrSpl = Split(Trim(arr(i, 3)), ",")
If Not dict.Exists(arr(i, 1)) Then
dict.Add arr(i, 1), Join(arrSpl, "|")
If UBound(arrSpl) 1 > colMax Then colMax = UBound(arrSpl) 1
Else
dict(arr(i, 1)) = dict(arr(i, 1)) & "|" & Join(arrSpl, "|")
If UBound(Split(dict(arr(i, 1)), "|")) 1 > colMax Then colMax = UBound(Split(dict(arr(i, 1)), "|")) 1
End If
Next i
ReDim arrFin(1 To dict.count, 1 To colMax 2)
For i = 0 To dict.count - 1
arrFin(i 1, 1) = dict.Keys()(i)
arrSpl = Split(dict.items()(i), "|")
arrFin(i 1, 2) = UBound(arrSpl) 1
For j = 0 To UBound(arrSpl)
arrFin(i 1, j 3) = arrSpl(j)
Next j
Next i
'drop the final array content:
sh1.Range("A2").Resize(UBound(arrFin), UBound(arrFin, 2)).value = arrFin
End Sub
