December 2025 monthly summary for Anselmoo/spectrafit. Focused on restoring and enhancing PPTX-based reporting capabilities to support stakeholder-friendly presentations and faster reporting cycles. Key activity was reinstating the PPTX export pipeline by restoring the PPTX plugin and associated models, enabling conversion of SpectraFit outputs into PowerPoint presentations. This included exporting fitting plots and metrics into a structured PPTX format for improved reporting. The work involved a revert of a prior removal (commit dfb4434640bc62d2e8e5c1fb3748a2efee63f4fa) to restore PPTX export functionality with minimal risk. Overall, this enhancement improves reporting consistency, reduces manual effort, and strengthens the business value of SpectraFit deliverables.
