Mac-Cel
A Mac-native Office add-in suite for finance and consulting teams — the application audits formulas, flags spreadsheet risk, maps how your workbooks flow from sheet-to-sheet, and carries firm formatting standards through to your PowerPoint decks, without ever leaving the workbook.
Context
Analysts and consultants on Mac spend hours a week checking their own spreadsheet work by hand — Excel’s auditing and workbook-mapping tools have always favored Windows, and the Mac side lags behind or doesn’t exist at all. I wanted a native tool that takes that gap seriously instead of working around it.
Problem
A single misplaced formula, or a workbook that’s grown past what anyone still remembers, can quietly undermine a model nobody has time to re-check line by line. And once the numbers are right, most teams still lose time reformatting the same figures into a PowerPoint deck by hand.
Approach
I’m building a Mac-native Office add-in suite that audits formulas for risk, maps how a workbook’s sheets actually depend on one another, and carries firm-specific formatting standards straight through into PowerPoint — all without leaving Excel.
Result
Still early, but the goal is concrete: give finance and consulting teams confidence that a workbook is sound and that the decks built from it look the way the firm expects, without the manual double-checking that eats into the work that actually matters.
