How to Save a CSV with the Same Name in Excel VBA: Overcoming the Run-time error '1004'

When working with CSV files in Excel using VBA, you might encounter the frustrating Run-time error '1004'. This error occurs when you try to save a workbook that has the same name as an already opened workbook. In this post, we'll walk through how to effectively manage saving a CSV file with the same name by altering your existing VBA code.

Understanding the Issue

While running a macro that interacts with a CSV file, you likely initiate a read-only session of that file. When trying to save changes, Excel generates the above error because it identifies that the same file is currently active. This is particularly critical if there are external tools or scripts that depend on the CSV file name.

The Error Explained

Error Code: 1004

Message: You cannot save this workbook with the same name as another open workbook or add-in.

This hamper with automation can be overcome by modifying how your macros interact with the workbook and worksheet objects.

Step-by-Step Solution

In this section, we’ll break down the solution to ensure your code works effectively without throwing the runtime error. The approach here involves passing the worksheet as an argument to the macro instead of relying on the active sheet, as this avoids name clash errors when saving.

Updating the Main Macro

Avoid Read-Only Mode: Ensure your CSV file is not opened in read-only mode, which prevents saving changes directly.

Pass Worksheet Object: Instead of relying on ActiveSheet, pass the worksheet object directly to the loop processing macro.

Here’s the revised code for your main macro:

Updating the Processing Macro

In the second macro (LoopColumnC), allow it to accept a worksheet object to streamline the operations on that specific sheet:

Receive the Worksheet Object: This allows the macro to know exactly which sheet to manipulate.

Save with the Same Name: Use the Parent property of the worksheet to save the containing workbook with the same name.

Here’s how you will modify the macro:

Key Takeaways

Avoid Naming Conflicts: Always ensure you handle the workbook and sheet objects accurately within your macros to prevent common Excel errors.

Use Worksheet References: Always pass worksheet objects to perform operations, which leads to more robust and error-free macros.

By following these steps, you should be able to save your CSV file without encountering the Run-time error '1004' and maintain the functionality required by any external tools that rely on that specific file name.

Implement these adjustments, and streamline your Excel VBA workflows today!
