Introduction

Working with strings in Excel can sometimes be a bit tricky, especially when you need to modify or manipulate them. A common scenario involves needing to remove unwanted parts of a string, such as dates that are surrounded by brackets. This task can be efficiently executed using VBA (Visual Basic for Applications), a powerful tool embedded in Excel for advanced automation.

One such example is when you have a string formatted like this: 23.08.2020 (21.08.2020) and you want to remove everything from the opening bracket to the closing bracket, including the brackets themselves. In this guide, we will walk through how to achieve this in a few simple steps using VBA.

Understanding the Problem

Given a string, the goal is to remove the portion from the first opening parenthesis ( to the closing parenthesis ) along with the parentheses. Here’s the step-by-step approach to tackle this problem:

Identify the position of the first opening parenthesis using the InStr() function.

If the opening parenthesis is found, extract the portion of the string before it.

If the parenthesis is not found, return the entire string.

Step-by-Step Solution

1. Set Up Your Environment

Make sure that you have enabled the Developer tab in Excel to access the VBA editor. Here's how:

Open Excel and navigate to File - Options.

In the Excel Options dialog, select Customize Ribbon.

On the right pane, check the Developer option and click OK.

Now you can access the VBA editor by clicking on the Developer tab and selecting Visual Basic.

2. Write the VBA Code

Below is a simple VBA macro that accomplishes the task of removing part of a string. Let’s break down the code:

3. Explanation of the Code

InStr Function: This function is used to find the position of the first occurrence of a substring (the opening parenthesis ( in this case) within the main string.

Left Function: This function returns the specified number of characters from the left side of a string. It’s used to extract everything before the detected position of the parenthesis.

Debug.Print: This is used to display the output in the Immediate Window, allowing you to verify the result easily.

4. Execution

To run the macro:

Return to the Excel worksheet.

Place your date string in cell A1 (e.g., 23.08.2020 (21.08.2020)).

Go back to the VBA editor and click Run (or press F5) to execute the RemoveStringPart() macro.

5. Result

After running the macro, if the appropriate cell contained 23.08.2020 (21.08.2020), the output should display 23.08.2020, which is the desired result.

Conclusion

Using VBA to manipulate strings in Excel opens up a world of possibilities for data management and cleaning. In this post, we explored a straightforward way to remove parts of a string, focusing on how to eliminate unwanted portions including brackets.

With the provided example and explanation, you now have the tools to perform similar string manipulations in your own Excel projects.
