Fix, Correct, and Upgrade Your Spreadsheet or Excel ToolThomas Biziouras
If your spreadsheet is confusing, broken, or outdated — I can turn it into a clean, powerful, and easy-to-use tool.
I help professionals, freelancers, and small teams fix and upgrade their Excel workbooks, whether they were built years ago or yesterday. From small fixes to full overhauls, I work with clarity, logic, and structure — making sure everything runs smoothly and is easy to maintain.
What I do:
🧼 Fix broken formulas, broken links, errors, and validation issues
🧠 Reorganize layout and logic for better clarity and flow
🔁 Update dropdowns, named ranges, tables, and structure
⚙️ Repair or upgrade VBA (buttons, macros, workflows)
🧾 Create or improve dashboards, reports, and summaries
💾 Modernize your file to be scalable, readable, and cloud-ready
Every spreadsheet is restructured using clean Excel logic: proper table architecture, named ranges, and intuitive UI. I never use third-party add-ins — only native, portable, and understandable Excel.
What's included
Repaired and Cleaned Excel File
All broken logic fixed (formulas, references, structure)
Visual Cleanup (optional)
Reorganized layout, table formatting, and better structure
Upgrade Suggestions
Short list of improvements for future scaling or automation
FAQs
No problem — I’ll audit the file and tell you what needs fixing and why.
Only if it helps simplify things. Otherwise, I stick to formulas and named ranges.
Yes — I often reorganize and format the workbook to be easier to read and use.
Absolutely. You get a fully editable Excel workbook with no hidden restrictions.
I handle budgeting tools, dashboards, calculators, trackers, planners, and business models.
No. I build 100% Excel-native solutions (VBA/macros included if needed).
