The problem

What was getting in the way.

Monthly reporting required manually copying data from multiple Excel workbooks into PowerPoint, creating a slow and error-prone process.

Why it was hard

Manual copy and paste

Data was copied by hand from multiple Excel workbooks into PowerPoint.

Error-prone

Manual transfer introduced avoidable mistakes.

Repetitive

The same manual process repeated every reporting cycle.

Time-consuming

Significant analyst and finance time went on formatting, not analysis.

The solution

What was built.

Designed a platform that analyses PowerPoint templates, maps KPIs to Excel once and automatically generates future reports while preserving layouts. Built with a roadmap for AI commentary, financial projection workflows and data warehouse integration.

Design decisions

  • Map KPIs to Excel once, then reuse the mapping indefinitely.
  • Preserve the original template layout exactly.
  • Design for extension: AI commentary and projections from day one.
