我的工作動態的外部工作簿的數據在Excel中引用的外部工作簿可以有人幫考慮以下幾點:鏈接到基於另一個細胞

在我的A2工作簿我有 = 'C:\'&A1&' Reports\[1.xls]Sheet1'!C1)

A1將包含任一

文件夾A
文件夾B

所以取決於A1的價值,我想以指向

d:\文件夾A報告\ 1.xls
d:\文件夾B報告\ 1.xls

我該如何做到這一點?

謝謝!

你可以使用一個IF語句或VLOOKUP表。這當然假設你只需要返回一個取決於查找值的值。 –

謝謝你的幫助!我只是希望將文件夾A填充到A2的路徑中,就像調用變量一樣。這樣做不可能嗎? – Andrew

這當然是可能的,但我很抱歉,因爲我不完全確定你要完成什麼。您當然可以根據A1的值填充路徑,並且有幾種方法可以實現此目的。正如我所指出的,查找是這樣做的一種方式。我覺得雖然你想要一個公式自己找到路徑,而不需要在表格中提供它。這也是可能的,但這將進入VBA的領域,而不僅僅是Excel的公式。 –

間接是你需要的功能:

=INDIRECT("'C:\" & A1 & " Reports\[1.xls]Sheet1'!C1") 

我看到,雖然問題是如果該表不是打開它不會解決。

謝謝你的回答。如果我硬編碼的路徑,我可以簡單地打開工作簿,並關閉它,數據將更新...所以我寫了一個宏,將打開我需要的所有電子表格,並關閉它們...對於INDIRECT函數,電子表格必須保持打開狀態,還是可以使用相同的宏來打開和關閉我的外部源? – Andrew

打開它,刷新它,關閉它,它將保持答案。我不得不問,爲什麼不直接從工作表中複製代碼中的數據,並將它作爲一個值放入目標工作表中,並且在運行時沒有依賴關係? –

手動操作太多了。很多標籤和來源......迫不及待地回家嘗試一下。再次感謝! – Andrew

由於INDIRECT不能在封閉的書工作,它是有昂貴的開他們,那麼這種情況的正常soutions是

  1. 創建VBA一個鏈接。從Morefunc插件。
  2. 我的首選方法是用XLM其中Harlan Grove在他的下拉功能有所改進。

要使用你的目的:

=pull("'C:\"&A1&"\"&"[1.xls]Sheet1'!C1")

'still more fixes, this time to address apparent differences between 
'XL8/97 and later versions. Specifically, fixed the InStrRev call, 
'which is fubar in later versions and was using my own hacked version 
'under XL8/97 which was using the wrong argument syntax. Also either 
'XL8/97 didn't choke on CStr(pull) called when pull referred to an

到關閉文件的外部引用在Excel公式不能動態的,所以也許如此mething這樣的:

=IF(A1="Folder A", 'C:\Folder A Reports\[1.xls]Sheet1'!C1, 
        'C:\Folder B Reports\[1.xls]Sheet1'!C1)
