About this Gig
Is your spreadsheet throwing #VALUE!, #N/A or #REF! errors, giving the wrong totals or grinding to a halt? I'll find the cause and fix it properly.
I'm a UK-based Excel specialist with 20 years of hands-on experience, now studying Software Engineering. That engineering mindset shapes how I work: clean, efficient, logical formulas that are easy to read, easy to maintain and built to scale, not quick patches that break next month.
What I can help with:
- Broken formulas and errors (#VALUE!, #N/A, #REF!, #DIV/0!)
- Lookups and logic: XLOOKUP, INDEX/MATCH, SUMIFS, nested IFs
- Dynamic array formulas (FILTER, UNIQUE, SORT)
- Slow, bloated or messy workbooks
- Data cleaning, processing and restructuring
- Formula audits and model logic checks
Why work with me:
- Clear, jargon-free communication from a native English speaker
- I explain what I changed and why, so you stay in control
- Your files are handled in confidence
- Friendly, reliable service and fast turnaround

FAQ
What do you need from me to get started?
Your workbook (or a copy with any sensitive data removed) and a short description of what's wrong or what you'd like it to do. Screenshots of the problem help too.
Which versions of Excel do you support?
Microsoft 365 and recent desktop versions of Excel. If a fix relies on a newer function, I'll tell you up front and offer a compatible alternative where possible.
Will you explain the changes you make?
Yes. Every delivery includes a short summary of what was wrong, what I changed and why, so you can maintain the spreadsheet with confidence.
