Question details

The user needs to pull data from an external Excel file where the file path, workbook name, sheet name, and cell address are dynamically generated by concatenating text.

How to Retrieve a Value from a Dynamic External Excel Reference

Product: Excel
Device & OS: not provided
Scenario: Attempting to use a concatenated text string representing an external file path to pull data from a closed workbook into the current spreadsheet.
Observed behavior: Excel treats the concatenated file path as standard text rather than an executable reference. Standard functions like INDIRECT return errors if the external workbook is closed, preventing the formula from resolving dynamically.

Before you start

Verify the exact file path, workbook name, and sheet name of your target external file. Since the most reliable solution involves VBA macros, ensure your Macro Security settings allow execution and that the Developer tab is enabled in your ribbon.

Solution 1Recommended

Retrieve Dynamic External Values Using a Custom VBA Function

Because standard formulas cannot evaluate a dynamic text path to a closed workbook, a custom VBA function utilizing ExecuteExcel4Macro is the most effective approach.

The ExecuteExcel4Macro method allows VBA to execute Excel 4.0 macro functions, which can retrieve a value from a closed external workbook without needing to physically open the file in the background.

By writing a custom user-defined function (UDF) in VBA, you can pass the path, file, sheet, and cell reference dynamically, which VBA will construct and evaluate.

Open the VBA Editor

Enable the Developer tab in Excel, then click on 'Visual Basic' or press ALT + F11 on your keyboard to open the VBA Editor.

Insert a New Module

In the VBA Editor menu, click 'Insert' and select 'Module' to create a new standard code module.

Paste the Custom Function Script

Create a function (for example, GetValue) that accepts arguments for path, file, sheet, and range. Inside the function, construct the reference string and apply ExecuteExcel4Macro to return the target value.

Save as a Macro-Enabled Workbook

Click 'File' > 'Save As' and ensure you select 'Excel Macro-Enabled Workbook (*.xlsm)' from the file format dropdown.

Use the Function in Your Worksheet

Return to your active worksheet and use the newly created function like a regular formula, e.g., =GetValue("C:\Users\PC\Documents\", "B.xlsx", "Sheet1", "A1").

Retrieve Dynamic External Values Using a Custom VBA Function

Security Consideration: Only run macros and establish dynamic connections to external files from trusted sources to mitigate potential security risks.

Solution 2

Import Data Dynamically Using Power Query

If you are not familiar with VBA and want a low-code alternative, Power Query can be parameterized to dynamically import data from external workbooks.

Frequently Asked Questions

Why doesn't the INDIRECT function work for closed external workbooks?

The INDIRECT function in Excel is designed to evaluate dynamic text strings into cell references, but it strictly requires the referenced external workbook to be open in the background. If the target workbook is closed, INDIRECT will return a #REF! error.

What is ExecuteExcel4Macro and how does it help?

ExecuteExcel4Macro is a legacy VBA method that executes Microsoft Excel 4.0 macro functions. It is highly valuable for this specific scenario because it possesses the unique capability to extract values from a closed external workbook without explicitly opening the file.

Can I achieve dynamic external references without using VBA or Power Query?

Generally, no. Without VBA scripts or Power Query parameters, native Excel formulas cannot evaluate a dynamically constructed text string into an actionable reference for a closed workbook.

How do I resolve macro security warnings when using custom VBA functions?

To manage macro security, go to File > Options > Trust Center > Trust Center Settings > Macro Settings. Select 'Disable all macros with notification' so you can manually approve the execution of your custom dynamic reference script each time you open the workbook.
