This project showcases my ability to transform messy, unstructured data into clean, organized, and actionable insights using Excel.

I worked with raw datasets containing inconsistencies such as duplicate entries, inconsistent formatting, and missing structure. I cleaned and standardized the data, ensuring accuracy and consistency across all fields.

From there, I built organized tables and dashboards to highlight key metrics such as revenue, profit, and performance by category and region. I also used formulas (including SUMIFS and calculated fields) to automate insights and improve usability.

This type of work is ideal for clients who need:

Clean and structured data

Reliable reporting

Easy-to-read dashboards

Improved data accuracy

The end result is a clear, professional spreadsheet that turns raw data into meaningful insights.

The before and after view of the data cleaning really shows the value clearly — clients often don't realise how much time messy data costs them until they see it laid out like this. The monthly sales dashboard with KPIs on top is a clean layout too. Did you build this for a real client or as a portfolio piece?
