Optimize Slow Excel Workbook

Mere paas ek heavy Excel workbook hai jisme Mixed data (numeric aur text dono) bhara hua hai. File ke andar multiple sheets Haan, aur Dono macros aur formulas hain jo ab performance ko kaafi slow kar rahe hai. Mujhe chahiye: • Workbook ko clean karo—redundant rows, blank cells, stray formats, hidden objects sab remove karo. • Existing formulas aur macros ko audit karke simplify/optimize karo taaki unki calculation time ghat jaaye aur functionality bilkul same rahe. • Calculation settings, pivot caches, named ranges, conditional formatting, links etc. ko review karke jo bhi bottlenecks hain unhe fix karo. • End result: file open, save, scroll, aur calculate karne me noticeable speed gain mile without breaking anything. Final deliverables: 1. Optimized workbook ready for use. 2. Short change-log batata hua kya-kya tweak kiya. 3. Optional tips so future me file dubara heavy na ho. Agar aapko VBA profiling, formula rewriting (INDEX-MATCH, dynamic arrays), Power Query, ya data model optimization ka experience hai to kaam bahut jaldi ho sakta hai. Drop me a brief plan aur turnaround time; main file turant share kar dunga.
