Why this program matters

  • Without mastery of advanced Excel manipulation with EPPlus in .NET, .NET developers and BI analysts lose an average of 12 hours per week on time-consuming manual processes prone to errors.

  • 65 % of reporting incidents stem from poor Excel file management, generating estimated losses of 8 000 € per critical error in time and data reconversion.

  • These gaps expose the company to risks of regulatory non-compliance and loss of competitiveness, while careers stagnate against more agile automated teams.

  • Each month without these skills equates to 15 000 € wasted and increased business vulnerability.

Before, during, after: we frame the brief, introduce the trainer, tailor the content and measure impact. You stay in control from kickoff to wrap-up.

Rigorous trainer selection

Each trainer is validated on three criteria: hands-on field expertise, proven pedagogy and alignment with your industry.

  • Triple validation: technical, pedagogical, sectoral.
  • Minimum rating 4.8/5 over the last 12 sessions.
Step 2

You meet the trainer beforehand

30-minute video call between you and the selected trainer to validate the fit, adjust content and clear any final doubts.

  • Live briefing on goals and team context.
  • Veto right — we swap the trainer for free if needed.
Step 3

Content tailored to your context

  • Program co-written then validated by your team.
Step 4

Continuous quality follow-up

Live evaluations, 30/90/180-day check-ins and a consolidation plan. If the impact misses the mark, we rework it.
