Data Cleaning & Business Data Analysis

Service
Turn messy spreadsheets and exports into reliable data and clear insights. I clean and structure your data so you can trust the numbers and use them for decisions.
Overview

Messy data leads to wrong conclusions. Duplicates, inconsistent formats, and mixed sources make it hard to trust any report. I clean and organise your data so it's ready for reporting, dashboards, or further analysis—and I can run analysis to answer specific business questions.

This is one of the most practical ways to start: get your data in shape, then build from there. Ideal for smaller projects or when you need a solid foundation before investing in dashboards or automation.

What you get: Clean, documented datasets and analysis-ready outputs. Where needed, I deliver clear findings and recommendations so you can act on the data.

Who it's for: Teams with data in spreadsheets, CSV exports, or multiple sources that need to be consolidated and made reliable.
