我有这个手机：
="='C:\Daily Reports\" & A1 & "\" & B1 &"\[Report " & C1 & ".xls]Report'!K4
它将创建一个如下字符串：
='C:\Daily Reports\2015\11\[Report 03Nov15.xls]Report'!K4
K4如果我获取该字符串并手动将其复制到另一个单元格，它将按照我的要求查找该工作表的值。
但是，我不知道如何使用 Excel 自动将我创建的字符串转换为公式。
我尝试过使用=INDIRECT，但它不起作用，因为它需要我引用的工作簿处于打开状态。我也试过
Function Eval(Ref As String)
Application.Volatile
Eval = Evaluate(Ref)
End Function
但同样，它要求工作簿处于打开状态。
有人知道我该怎么做吗？我觉得我已经接近目标了，但我搞不清楚最后一步。我宁愿完全使用 Excel 公式来完成，但如果需要，使用 VBA 函数也可以。
提前致谢。

我的解决方案是使用这个版本的IndirectEx
'------------------------------------
'Extended INDIRECT Function v1.0

'Copyright (c) 2009 Wilson So.

'------------------------------------
'Credits:
'- Designed and written by Wilson So.
'- The 'CreateObject("Excel.Application")' trick was inspired by Harlan Grove's PULL function source code.

'This is an open source. You can freely redistribute and modify it, but please kindly give credit to the contributers.
'Please also kindly report any bugs/suggestions through e-mail or in the forums where I posted it.
'------------------------------------
'How to use:
'- Basically same as INDIRECT() in Excel - the same concept for the ref_text parameter.
'- To update the static memory for a particular reference,
' type TRUE in the second parameter (just one of the IndirectEx() containing that reference)
' and calculate it once.
'------------------------------------
'Features:
'- You can refer to the closed workbook data.
'- The retrieved closed workbook data will be stored in the static memory,
' so in the next time, the closed workbook will not be opened again for fast retrieve.
'- A range instead of an array will be returned if the path is omitted in the ref_text,
' so it still works fine if the user refers to an enormous array, e.g. "Sheet1!1:65536".
'- You can use it inside INDEX(), VLOOKUP(), MATCH() etc.
'- You can use it with OFFSET(), but only for opened workbook data.
'- The procedure will not blindly retrieve all the data as requested;
' it will not retrieve data beyond the "Ctrl + End" cell, in order to keep the memory as small as possible.
'- #NUM! will be returned in case of lack of memory.
'- #REF! will be returned in case of a wrong path.
'- #VALUE! will be returned in case of other errors.
'------------------------------------
'Known issues:
'- Due to the use of SpecialCells(), #VALUE! will be returned if the worksheet for a closed workbook is protected.

Excel 中没有内置现成的解决方案。免费的 Morefunc.xll 有一个名为 Indirect.Ext 的自定义函数，可与关闭的工作簿配合使用。您可以在此处下载：
