In the world of Excel VBA, one task stands out for its critical impact on data accessibility and efficiency: network drive mapping with Excel. This guide demystifies the process, showing you how to master network drive mapping using Excel VBA, a skill essential for any Excel analyst in today’s interconnected professional environments.

The Universal Network Drive Problem

Excel VBA offers a powerful toolset for professionals, but it comes with its unique challenges, especially in a corporate setting. A prime example is the universal network drive problem.

When Excel analysts develop VBA scripts or Excel files for organizational use, they often face the hurdle of inconsistent network drive mapping. This inconsistency can cause major disruptions, particularly when files are shared across a diverse team.

Imagine a typical scenario in network drive mapping with Excel: an Excel dashboard is created with a button linking to a shared network file. While the file opens perfectly on the creator’s computer, mapped to the ‘Z‘ drive, it becomes inaccessible to colleagues who have their network drives mapped differently, such as to ‘U‘ or ‘X‘ drives.

This issue leads to Excel’s inability to locate the file, resulting in broken links and workflow interruptions. Addressing this challenge calls for strategies that ensure uniform network drive mapping, enhancing file accessibility and maintaining smooth operations across the business.

Example

For instance, consider this VBA code snippet designed to open a reference file:

Sub OpnRef()
    Application.Workbooks.Open ("Z:\Shared Report Area\Reference Docs\Reference1File.xlsx")
End Sub

This code works flawlessly on your machine, with the ‘Z‘ drive mapped. However, if another user has the shared location mapped to their ‘U‘ drive, Excel fails to find the file, as it searches in the user’s ‘Z‘ drive, which may not even exist.

Universal Network Drive Mapping with Excel VBA

The Solution

The solution is to change the way you specify the location of the file using VBA and for this you utilise the UNC, Universal Naming Convention.  More detail can be found on the UNC here but the basic premise is that you are changing the location of the file to use the full server path location, the format it takes is:

  • \Server\Share\filepath

We can use this way of locating a file/folder in our VBA scripts for Excel.  So the previous VBA script that specified the file was on the Z drive would now look like this:

Sub OpnRef()

Application.Workbooks.Open ("\\Server\Share\Shared Report Area\Reference Docs \Reference1File.xlsx")

End Sub

The section for \\Server\Share replaces the drive letter and after that you specify the file path as per normal, remembering to still point to the specific file to open.

Important Note

\Server\Share is the uniform way of describing the location, you will need to change this part to your exact server name and shared area.  If you are struggling to determine this you can usually get assistance from an the in-house IT team.

To do it yourself the quickest way is to open Windows Explorer and locate the path that points to shared area in question, for example if you are mapped to the Z drive it will say something along the lines of:

  • Shared on ‘xxxx\xxxx\xxxx’ (Z:)

Your \Server\Share section is everything in-between the apostrophes, so that’s the bit reading xxxx\xxxx\xxxx in the above example.

Summary

Incorporating Universal Naming Convention (UNC) paths in your VBA scripts is a straightforward yet effective practice, especially when dealing with network drive mapping with Excel. This approach guarantees that the scripts you write are transferable and functional across various segments of your business, eliminating the need for ongoing support or future modifications.

UNC paths can be easily identified through Windows Explorer, allowing you to replace specific drive letters in your scripts with these universal paths. Adopting this method not only streamlines your workflow but also saves significant time in the long run.

Embrace this efficient process today to enhance the usability and reliability of your Excel-based projects within the business environment.
