Practical Excel help from someone who understands the problem

Hi, I’m Mark.
I help people fix spreadsheets, improve reports and make better use of Microsoft Excel and Microsoft 365.
If you have a spreadsheet that has become slow, confusing, unreliable or too important to risk getting wrong, I can help you understand what is happening and find a practical way forward.
Why I can help
I have years of hands-on experience building and improving spreadsheets, dashboards, trackers and reporting tools.
My work includes:
- fixing broken formulas
- simplifying complicated workbooks
- building reports and dashboards
- using Power Query to clean and combine data
- creating Power BI reports
- improving Microsoft 365 processes with SharePoint, Forms and Power Automate
I work best where Excel is being used to solve real business problems, tracking performance, managing information, reporting progress or replacing time-consuming manual processes.
My approach
I keep things clear, practical and easy to use.
That means:
- no unnecessary jargon
- no over-complicated solutions
- clear explanations
- reliable spreadsheets
- tools designed around how you actually work
The aim is simple: to save you time, reduce errors and give you confidence in your data.
