方案一：資料少時省事private sub customtransform1()
dim wb as workbook, sht as worksheet
dim newsht as worksheet, dic as object
dim endrow as long, irow
set dic = createobject("scripting.dictionary")
set sht = wb.worksheets("原始資料")
'新建一張工作表，若之前已經存在同名工作表，直接刪除
set newsht = wb.worksheets.add(after:=wb.worksheets(wb.worksheets.count))
on error resume next
wb.worksheets("轉置結果").delete
on error goto 0
newsht.name = "轉置結果"
newsht.cells.clearcontents
with sht
endrow = .cells(.cells.rows.count, 1).end(xlup).row
for i = 1 to endrow
key = .cells(i, 1).value
'當a列的某個資訊第一次出現時，為它編排乙個序號，同時作為轉置後的行號
if dic.exists(key) = false then
dic(key) = dic.count + 1
end if
irow = dic(key) '輸出的行號
newsht.cells(irow, "a").value = key
newsht.cells(irow, "iv").end(xltoleft).offset(0, 1).value = .cells(i, 2).value
next i
end with
'釋放物件
set dic = nothing: set wb = nothing
set sht = nothing: set newsht = nothing
end sub
方案二：資料多時效率相對高點
private sub customtransform2()
dim wb as workbook, sht as worksheet
dim newsht as worksheet, dic as object
dim arr(), ar as variant
dim endrow as long, endcol as long
set dic = createobject("scripting.dictionary")
set sht = wb.worksheets("原始資料")
'新建一張工作表，若之前已經存在同名工作表，直接刪除
set newsht = wb.worksheets.add(after:=wb.worksheets(wb.worksheets.count))
on error resume next
wb.worksheets("轉置結果").delete
on error goto 0
newsht.name = "轉置結果"
newsht.cells.clearcontents
with sht
endrow = .cells(.cells.rows.count, 1).end(xlup).row
set rng = .range("a1:b" & endrow)
ar = rng.value
r = 0
redim arr(1 to endrow, 1 to 20) '構造二維陣列
for i = lbound(ar) to ubound(ar)
key = cstr(ar(i, 1))
if dic.exists(key) = false then
dic(key) = 1
else
dic(key) = dic(key) + 1
end if
r = dic.count: c = dic(key)
arr(r, 1) = r: arr(r, c + 1) = ar(i, 2)
next i
end with
'快速輸出結果
newsht.range("a1").resize(ubound(arr), ubound(arr, 2)).value = arr
'釋放物件
set dic = nothing: set wb = nothing
set sht = nothing: set newsht = nothing
end sub

Json資料格式
在web 系統開發中，經常會碰到客戶端和伺服器端互動的問題，比如說客戶端傳送乙個 ajax 請求，然後在伺服器端進行計算，計算後返回結果，客戶端接收到這個響應結果並對它進行處理。那麼這個結果以一種什麼資料結構返回，客戶端才能比較容易和較好的處理呢？通過幾個專案的實踐，我發現 json 格式的資料是一...
JSON資料格式
下面這段文字，摘錄自留作備忘 21世紀初，douglas crockford尋找一種簡便的資料交換格式，能夠在伺服器之間交換資料。當時通用的資料交換語言是xml，但是douglas crockford覺得xml的生成和解析都太麻煩，所以他提出了一種簡化格式，也就是json。json的規格非常簡單，只...
