Advanced Excel
Excel is the foundation of my reporting work — P&L builds, reconciliation tools, and financial models. The discipline that matters is structure and control: inputs separated from calculations, formulas instead of copy-paste, and every report tied out line by line.
The Workflow — How I Approach It
Build with structure
Separate inputs, calculations, and outputs — so the model is readable and auditable.
Use formulas for control
Let formulas do the work — hard-coded numbers are errors waiting to happen.
Tie out every line
Check the report against the ledger line by line before it’s shared.
Automate recurring builds
Turn monthly models and schedules into repeatable templates.
My Operating View — The 2 Cents
Most spreadsheet errors aren’t formula bugs — they’re structural. My 2 cents: a model should be auditable by someone other than its author. Clean structure and live formulas mean the person reviewing it can trust it — and so can the decision it supports.
What Worked & What Didn’t
What Worked
- Structured models that survived review and reuse across periods.
- Line-by-line tie-outs that caught errors before publication.
What Didn’t
- Hard-coded numbers and copy-paste — silent, compounding errors.
- One-off files rebuilt from scratch every month — wasted time, more risk.
