How to Convert VBA Code to Python Fast in 3 Minutes (Excel)

Written by Kasper Langmann

Converting VBA (Visual Basic for Applications) code to Python can seem like a daunting task, especially if you’re new to Python or have a significant amount of VBA code to convert. However, with the right approach and tools, this process can be fast and efficient. This guide will walk you through the steps to convert VBA code to Python in just three minutes.

Understanding the Basics of VBA and Python

Before diving into the conversion process, it’s important to understand the basics of both VBA and Python. VBA, or Visual Basic for Applications, is an event-driven programming language developed by Microsoft. It is primarily used for automating tasks in Microsoft Office applications, including Excel.

Python, on the other hand, is a high-level, interpreted programming language known for its simplicity and readability. It is widely used in various fields, including web development, data analysis, machine learning, and more. Python’s syntax is quite different from VBA’s, which can make the conversion process challenging.

Key Differences Between VBA and Python

While both VBA and Python are powerful programming languages, they have several key differences. For instance, VBA is a statically-typed language, meaning you have to declare the type of a variable when you create it. Python, however, is dynamically-typed, so you can change the type of a variable at any time.

Another significant difference is how the two languages handle arrays. In VBA, arrays are zero-based or one-based, while in Python, all arrays are zero-based. This difference can lead to errors if not properly accounted for during the conversion process.

Tools for Converting VBA to Python

There are several tools available that can help you convert VBA code to Python. These tools can automate much of the conversion process, saving you time and effort. However, it’s important to note that these tools are not perfect and may not be able to convert all VBA code accurately. Therefore, manual review and adjustment of the converted code is often necessary.

One popular tool for converting VBA to Python is vb2py. This open-source software can convert VBA projects into Python code. It also includes a GUI for easy use. Another tool is the online converter at, which can convert VBA code to Python online for free.

Using vb2py for Conversion

To use vb2py, you first need to download and install the software. Once installed, you can open the vb2py GUI and select the VBA project you want to convert. The software will then convert the VBA code into Python code, which you can review and adjust as necessary.

While vb2py can handle most VBA code, it may struggle with more complex code. In such cases, you may need to manually convert the code or seek assistance from a Python expert.

Using Online Converters

Online converters, like the one at, are another option for converting VBA to Python. To use these converters, you simply paste your VBA code into the converter and click the ‘Convert’ button. The converter will then generate Python code, which you can copy and paste into your Python environment.

Like vb2py, online converters may not be able to accurately convert more complex VBA code. Therefore, manual review and adjustment of the converted code is often necessary.

Manual Conversion of VBA to Python

While automated tools can be helpful, they are not always able to convert all VBA code accurately. Therefore, it’s important to understand how to manually convert VBA code to Python. This process involves understanding the syntax and structure of both languages and being able to translate VBA code into Python code.

Manual conversion can be a time-consuming process, especially for larger VBA projects. However, it can also be a valuable learning experience, helping you to better understand both VBA and Python.

Translating VBA Syntax to Python Syntax

The first step in manual conversion is to translate VBA syntax to Python syntax. This involves replacing VBA keywords with their Python equivalents, changing the syntax of loops and conditional statements, and adjusting the way arrays are handled.

For instance, a VBA ‘For’ loop would be translated to a Python ‘for’ loop, with the syntax adjusted accordingly. Similarly, a VBA ‘If’ statement would be translated to a Python ‘if’ statement, with the syntax adjusted to match Python’s syntax.

Adjusting for Python’s Dynamic Typing

Another important aspect of manual conversion is adjusting for Python’s dynamic typing. This involves removing type declarations from your VBA code and ensuring that variables are used consistently throughout your Python code.

For instance, if a variable is used as an integer in one part of your VBA code and as a string in another part, you would need to ensure that the variable is used consistently as either an integer or a string in your Python code.

Testing and Debugging Your Converted Code

Once you’ve converted your VBA code to Python, it’s important to thoroughly test and debug your code. This involves running your code in a Python environment and checking for any errors or unexpected behavior.

Python’s built-in debugging tools can be helpful for this process. These tools allow you to step through your code line by line, inspect variables, and identify where errors are occurring.

Using Python’s Built-In Debugging Tools

Python’s built-in debugging tools, such as pdb, allow you to step through your code line by line, inspect variables, and identify where errors are occurring. To use pdb, you simply import the pdb module and call pdb.set_trace() at the point in your code where you want to start debugging.

Once in debug mode, you can use various commands to step through your code, inspect variables, and more. This can be a valuable tool for identifying and fixing errors in your converted code.

Seeking Help from the Python Community

If you’re struggling with the conversion process or encountering errors you can’t resolve, don’t hesitate to seek help from the Python community. There are numerous online forums and communities where you can ask questions and get help with Python programming.

For instance, Stack Overflow is a popular online community where you can ask programming questions and get answers from experts. There are also numerous Python-focused forums and communities where you can get help with specific Python issues.


Converting VBA code to Python can be a challenging process, but with the right approach and tools, it can be done efficiently and effectively. Whether you choose to use automated tools or manually convert your code, it’s important to thoroughly test and debug your converted code to ensure it functions as expected.

Remember, learning a new programming language is a journey, and it’s okay to ask for help along the way. The Python community is a valuable resource for getting help with Python programming and learning more about this powerful language.
