Replicate Complex Excel Spreadsheet

I have an existing Excel model that I need rebuilt from scratch so it behaves exactly the same as the original. Every data format, formula, calculation chain, and embedded chart must mirror the source workbook one-to-one because it will feed directly into my financial analysis work.

Key elements to reproduce:
• All cell formats and data validation rules
• Every formula, including nested logic and named ranges
• Dynamic charts and graphs that update with new inputs
• Pivot tables for summarising large data blocks
• Clear conditional formatting that highlights variances and trends

The finished file should open cleanly in the latest desktop version of Excel, with no broken links or missing references. I will provide the source workbook and sample data; you return a fully functioning replica plus a brief change log so I can see what you touched.

I will test by running my usual financial scenarios—if totals, charts, and pivot outputs match the original, the job is done.
