Our company relies on one very large, multi-sheet Excel workbook as the master file for day-to-day operations. Over time it has grown bloated: formulas are scattered across dozens of tabs, formatting is inconsistent, and the file now freezes or takes minutes to calculate whenever we open, save, or filter data. The immediate goal is to eliminate every bottleneck. I need the entire workbook audited—specifically the formulas and overall formatting—to locate circular references, volatile functions, hidden conditional formats, broken named ranges, and anything else that drags performance down. Unused styles, excess rows/columns, and outdated links also have to go. Once the problems are identified, clean the workbook so it opens quickly, recalculates without hanging, and keeps a professional, uniform look. If rewriting complex formulas into more efficient alternatives or consolidating sheets with Power Query or VBA is the best route, feel free; the end product just has to be faster, lighter, and error-free. Deliverables • A streamlined, fully functional Excel file that no longer freezes • A short change log summarising key fixes (formula rewrites, removed styles, sheet consolidations, etc.) • Brief guidance on any new macros or Power Query steps added, so we can maintain the file internally Everything must stay in native Excel—no external databases or third-party add-ins.

Hi there, I’ve carefully reviewed your project and understand you need a full audit and optimization of a large, multi-sheet Excel workbook that’s currently slow, unstable, and difficult to maintain. I’m confident I can streamline it into a fast, clean, and reliable operational file. My approach is to systematically audit the workbook at both formula and structural levels identifying circular references, volatile functions, inefficient array formulas, hidden conditional formatting, broken named ranges, and external links. I’ll then optimize or rewrite heavy formulas, remove unused styles and excess ranges, and standardize formatting to improve both performance and usability. Where beneficial, I can consolidate logic using Power Query or lightweight VBA to reduce duplication and recalculation load, while ensuring everything remains fully within native Excel and easy for your team to maintain. My focus will be not just fixing issues, but restructuring the file so it stays efficient long-term. Deliverables include a fully optimized Excel file, a clear change log outlining all fixes and improvements, and simple guidance on any Power Query or VBA elements introduced. Do you want me to prioritize minimal structural changes, or am I free to reorganize sheets for maximum performance improvement? I’m ready to start immediately. Warm regards, Aneesa.

I checked the workbook, the fixed price fees will not be fair for this kind of fixes, there is no magical short cuts, no matter how skilled or clever is the developer, it need through out checks and careful adjustments. I prefer an hourly price model. if that sounds reasonable and fair for you let me know, Will be happy to start. regards.

Hi there, I understand you need a full performance audit and optimisation of a large, multi-sheet Excel workbook that has become slow, unstable, and difficult to maintain due to accumulated formulas, formatting issues, and structural inefficiencies. With strong experience in advanced Excel modelling, performance tuning, and VBA/Power Query optimisation, I can help transform your file into a fast, stable, and maintainable system. My approach will begin with a structured workbook audit to identify the core performance bottlenecks, including volatile functions (OFFSET, INDIRECT, TODAY, NOW), circular references, excessive array formulas, inefficient lookup patterns, broken named ranges, and hidden formatting overhead such as excessive conditional formatting rules and unused styles. I will also review sheet architecture for redundant calculations and oversized ranges that force unnecessary recalculation. Deliverable: A fully optimised Excel workbook that loads faster, recalculates efficiently, and remains stable under daily use, along with a change log detailing all improvements and a brief maintenance guide for any new logic introduced. QUESTION: Are you open to using Power Query as the primary replacement for heavy formula chains, or do you prefer to keep most logic strictly formula-based even if performance gains are smaller? Let’s get started and bring your workbook back to a smooth, production-ready state. Regards, Shehwani.
