鏈接到基於另一個細胞

Question

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：

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！

Answer 1

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。

Answer 2

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一個髒鏈接。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

'fixed the previous fix - replaced all instances of 'expr' with 'xref' 
'also now checking for initial single quote in xref, and if found

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)
