You will get clean, structured Excel data — duplicates and errors removed, formats fixed
Project details
Got a messy spreadsheet? I'll clean it up fast and hand it back ready to use. Whether your data has duplicates, inconsistent formatting, mixed date styles, blank rows, typos, or values that just don't make sense — I'll find every issue, fix what can be fixed, and flag anything that needs your input before I touch it. You'll receive a fully cleaned Excel file along with a change log documenting every change made. Anything ambiguous gets flagged for your review rather than changed without asking.
I've spent 20+ years working with data across financial services, healthcare, and manufacturing. Excel has been at the center of that work from day one. I know what clean data looks like and how to get there efficiently.
Turnaround is typically 1–2 business days depending on complexity. If I see something that's going to take longer than expected, I'll let you know before I proceed. Let's get your data sorted.

About Peter
Senior Data Analyst & BI Specialist | Excel Expert
Jeffersonville, United States - 1:55 am local time
I'm a Senior Data & Business Intelligence specialist with over 20 years of hands-on experience across enterprise environments in financial services, healthcare, manufacturing, and scientific industries. Excel has been at the center of my work from day one — and so has SQL Server, Power BI, SSRS, SSIS, and Azure.
Here's what I can help you with:
• Clean and organize messy data removing duplicates, standardizing formats, fixing errors (Excel or SQL)
• Build Pivot Tables, Power Query automations, and Excel dashboards your team will actually use
• Advanced Excel formulas — XLOOKUP, INDEX/MATCH, dynamic arrays, conditional logic
• Design and build Power BI dashboards and reports with real, actionable insight
• Architect or optimize your SQL Server database — stored procedures, indexing, performance tuning
• Build ETL pipelines with SSIS or Azure Data Factory to move and transform data reliably
• Set up or improve your SSRS reporting environment, including security and report development
• Migrate legacy data (FoxPro, Access, older SQL Server) to modern SQL Server or Azure SQL
• Design data models and data marts that make reporting fast and accurate
In my career I've built terabyte-scale data marts at Wells Fargo, replaced entire Excel-based reporting systems with SSRS and Tableau at Eurofins Scientific, managed 13 SQL Server instances at Bridgestone/Firestone, and administered Power BI and SSRS environments in healthcare. I've been the go-to person for complex data challenges — the one colleagues and management called when the spreadsheet broke or the reports stopped making sense.
Currently, I'm building a pro bono analytics platform for a 45-bed recovery residence — a full stack engagement from SQL Server star schema design and Python ETL through a 14-page Power BI dashboard, deployed to Azure SQL Database. It's the kind of project that shows what Business Intelligence can do for organizations that need it most.
I hold a Microsoft Power BI Data Analyst Associate certification, Microsoft certifications in SQL Server and Azure Data Fundamentals, and a Google Data Analytics Professional Certificate.
I work cleanly, communicate clearly, and deliver on time. Tell me what you're working with and let's get it sorted.
