Without mastering EPPlus, .NET developers resort to error-prone manual Excel handling, resulting in 40% of projects facing delays from corrupted files and formatting failures.
These mishaps cost companies an average of $75,000 annually per team in rework and lost productivity, according to industry benchmarks.
Moreover, 65% of data processing incidents stem from inadequate Excel automation skills, risking regulatory fines up to $1 million and severe reputational harm.
Every month without this expertise, businesses hemorrhage efficiency and expose themselves to competitive disadvantages that threaten long-term viability.
The EPPlus Initiation Training training is delivered in-person or remotely (blended-learning, e-learning, virtual classroom, remote in-person). At Learni, a Qualiopi-certified training organization, each program is designed to maximize skills acquisition, regardless of the training mode chosen.
