AvalCal – Automatic Evaluation & Presentation Generator
--- ##
Overview
AvalCal is a Python-based automation tool designed to process student evaluation spreadsheets and automatically generate formatted PowerPoint presentations with performance summaries and student imagery. The system was developed to simplify the preparation of evaluation reports and visual presentations by automating: - Excel data processing - Evaluation classification - Student ranking - PowerPoint slide editing - Automatic image insertion - Presentation generation The application combines spreadsheet manipulation with automated PowerPoint editing to accelerate academic and institutional reporting workflows. :contentReference[oaicite:0]{index=0} --- #
