Hi — I can merge your existing calculation files into a single, clean Excel master workbook and extend it with the required custom calculations. What I’ll deliver: Consolidated workbook with a clear structure (Inputs → Calculations → Outputs → Checks) so your team can maintain it easily. Migration of all existing logic with no broken links and consistent naming (tables/ranges). Implementation of new custom calculations, including complex math with audit-friendly formulas. For the differential equation requirement, I’ll implement the solution numerically in Excel (typical approaches: finite-difference / Euler / Runge–Kutta depending on stability and accuracy needs), using formulas and/or lightweight VBA where necessary. Validation sheet: cross-checks, bounds checks, and reconciliation so results can be trusted. A couple of quick scope questions to lock it precisely: What type of differential equations (ODE/PDE) and what’s the expected output (time-series, steady-state, optimization)? Any reference results (sample outputs) to validate against? How many source files/sheets and approximate size? Deepanshu — Excel models that behave like engineering calculators, not spreadsheets.

I can merge your existing Excel calculation files into a single, well-structured workbook and implement the required custom calculations with full mathematical accuracy. I have a strong background in mathematics and statistics, including practical use of differential equations, combined with extensive experience building complex Excel models. For this project, I will first consolidate all source files into one coherent structure, ensuring formulas, references, and dependencies remain intact and traceable. I will then design and implement the required custom calculations using advanced Excel formulas and, where appropriate, VBA to handle complexity or improve clarity. Differential equations will be handled using suitable numerical methods (such as finite difference or iterative approaches) implemented transparently in Excel so the logic is easy to review and validate. I am Google Data Analytics–certified and IBM Data Analyst–certified, and I work with a strong focus on correctness, documentation, and maintainability. All formulas will be clearly laid out, intermediate steps preserved, and assumptions noted so the final file is not a black box. The finished workbook will be clean, logically organized, and ready for further use or extension. I can start immediately and deliver within your stated budget and timeline.
