VBA Macro for Data Cleaning

In this VBA macro project focused on data cleaning, I built a custom Excel solution to automate the entire data preparation workflow for large and often messy datasets. The macro was specifically designed to take raw, unstructured data and turn it into a clean, analysis-ready format with minimal manual effort.

The process started by importing the raw data into Excel and setting up a structured environment with dedicated sheets and clearly defined dynamic ranges. From there, the macro took over to perform key data cleaning tasks such as:

Removing exact and near-duplicate records

Fixing common data entry issues (like inconsistent casing, extra spaces, or invalid characters)

Standardizing date formats, numerical precision, and categorical values

Reorganizing data into a uniform structure for downstream analysis or reporting

This VBA automation not only saved hours of manual work but also ensured data integrity across multiple files and use cases. It was built with scalability and reusability in mind, so it can be applied to different datasets without tweaking the code every time.

If you're dealing with repetitive Excel tasks or inconsistent data and need to streamline your workflow, this kind of tailored VBA solution is a game changer.
