Do you have Excel files that work, but take too much time, are difficult to maintain or read? I step in to transform them into reliable, automated, and directly usable tools — without rebuilding from scratch. With several years of experience in demanding operational environments (planning, HR reporting, contact center workforce tracking), I know what it's like to have a file used daily under pressure. I build tools that last. I intervene in particular on: - Automation of complex calculations (Lambda, XLOOKUP, nested formulas) - Cleaning and restructuring of large or poorly organized files - Creation of readable dashboards and reports, oriented towards decision-making - Advanced conditional formatting to visualize information at a glance - Extraction and consolidation of data from multiple sources My approach: I start with your existing file, I understand your real constraints, and I deliver something you can use and evolve yourself. 100% remote intervention. Deadlines met. Documented files.
