Question details

The VBA script creates and attempts to save an XLSX file silently, but the file cannot be located or fails to save properly.

How to Fix Excel VBA Save Problems When ScreenUpdating is Set to False

Product: Microsoft Excel
Device & OS: Windows
Scenario: Running an automated VBA procedure to generate and save a new workbook while Application.ScreenUpdating is disabled, especially after a recent Windows update.
Observed behavior: The macro completes execution without displaying any on-screen activity, but the newly generated XLSX file does not appear in the expected destination folder.

Before you start

Verify that your destination folder permissions have not changed after the recent Windows update, and ensure your VBA Editor is open by pressing Alt + F11.

Solution 1Recommended

Explicitly Declare Variables and Verify Save Paths

Fix incorrect inline variable declarations that default to Variants instead of Strings, which often results in invalid or empty save paths.

In VBA, declaring multiple variables on a single line like 'Dim path1, path2, filename As String' only declares the last variable as a String. The others default to Variants. This can cause path concatenation to fail silently when ScreenUpdating and DisplayAlerts are turned off, resulting in the file being saved to a default system directory instead of your intended folder.

Open the VBA Code Editor

Press Alt + F11 to open the Visual Basic for Applications (VBA) editor and locate the module containing your save procedure.

Update Variable Declarations

Find your path and filename variable declarations. Change them to explicitly declare each type. For example, change 'Dim nombreArchivo, rutaarchivo, archivo As String' to 'Dim nombreArchivo As String, rutaarchivo As String, archivo As String'.

Confirm the Destination Path

Add 'Debug.Print ThisWorkbook.Path' before your save command to verify the exact folder path in the Immediate Window (Ctrl + G) before the file saves.

Explicitly Declare Variables and Verify Save Paths

Best Practice: Using Option Explicit at the top of your VBA modules forces you to properly declare all variables, preventing subtle bugs related to undefined paths.

Solution 2

Implement a Cleanup Section for Error Handling

Ensure Application properties are reset properly even if the save procedure fails silently.

Frequently Asked Questions

Why does setting ScreenUpdating to False cause files to disappear?

Setting Application.ScreenUpdating to False doesn't delete the file, but it hides the background processes and error prompts. If your path variables are incorrect, the macro might fail silently or save the file to an unexpected default system folder without alerting you.

How do I correctly declare multiple string variables in VBA?

You must specify the data type for each variable individually. Instead of typing 'Dim path, filename As String' (which makes 'path' a Variant type), you must write 'Dim path As String, filename As String'.

Where does Excel VBA save a file if the path variable is empty?

If a path variable evaluates to empty, Excel typically saves the file to your system's default working directory, which is usually your 'Documents' folder or the directory where Excel was last opened.

Can a Windows update affect Excel VBA file saving?

Yes, Windows updates can sometimes reset default directory permissions or change how network paths resolve. Relying on explicitly defined paths using ThisWorkbook.Path ensures the macro finds the correct folder regardless of system changes.
