Sébastien Niolet

I am a freelance consultant and trainer specializing in optimizing business productivity through office tools, particularly Excel and Power Query. With several years of experience, I assist professionals, students, and companies in mastering data management and analysis tools to improve their daily efficiency.

My expertise is based on an advanced mastery of Excel functionalities, whether for creating interactive dashboards, automating processes, or managing complex data. I also offer training tailored to each level, from B1 to M2, in person and remotely, to make the use of Excel accessible and efficient, even for beginners.

In parallel, I develop custom solutions for companies, designing files adapted to their specific needs (inventory management, financial reporting, performance tracking, etc.). My teaching method is based on a pragmatic and action-oriented approach, so that each learner can quickly apply what they have learned in their professional environment.

Passionate about knowledge transfer and the optimization of business processes, I am determined to help my clients achieve their goals and increase their productivity.
