You will get to clean and organise your messy Excel or Google Sheets data
Project details
Messy data slows your business down and leads to decisions based on wrong numbers. I help small businesses and individuals clean, structure, and organise their spreadsheet data so it's accurate, consistent, and ready to use. I work in Excel, Google Sheets, and Power Query to remove duplicates, fix formatting errors, standardise inconsistent values, handle missing data, and deliver a clean, structured file with a brief summary of what was fixed. Every job is delivered on time with clear documentation — so you know exactly what changed and why.

Dass, Nigeria - 1:33 am local time
I'm a data analyst who works with small businesses, startups, and e-commerce brands to clean messy data, build dashboards that get used, and surface insights that drive real decisions — not just reports that sit in a folder.
My toolkit is practical and accessible: SQL for querying and transforming data, Excel for fast analysis and reporting, Power BI for interactive dashboards, and Google Sheets for collaborative, real-time reporting your whole team can use without needing a BI tool.
What I can help you with:
→ Data cleaning & prep — Messy spreadsheets, duplicate records, inconsistent formats — fixed and ready for analysis.
→ Dashboard & reporting — Power BI and Google Sheets dashboards built around your actual decisions, not just the data you have.
→ E-commerce analytics — Sales trends, product performance, customer behaviour — turned into clear, actionable findings.
→ Business analysis & insights — I translate raw numbers into plain-English findings your team can act on immediately.
I pay close attention to detail, communicate clearly throughout every project, and deliver work that's documented so you're never dependent on me to understand it.
I'm early in my freelance career, which means I'm selective about the projects I take on and fully committed to every one. You'll get my best work, clear updates, and on-time delivery — guaranteed.
Ready to turn your data into decisions? Send me a message with a brief description of your project and I'll respond within 24 hours with how I'd approach it.
