deck-refresh

To update financial numbers in an existing PowerPoint without breaking formatting, this Skill replaces outdated values with new ones while preserving original styles, fonts, and chart structures across text, tables, and charts.

Refreshing chart data and table values involves collecting an explicit old-to-new mapping, scanning all locations including chart-source numbers and footnotes, presenting an approval-gated change plan, and then executing minimal verified edits.

Updating PowerPoint charts requires modifying the underlying data source rather than just changing labels, ensuring chart displays and text narratives remain consistent while applying minimal necessary edits.

The best way to handle quarterly roll-forward updates for financial presentations is to enumerate every instance of old values including embedded numbers, generate a complete change list for approval, and then execute edits with visual verification.

Yes, you can review changes before the Skill edits your presentation deck because the workflow uses an approval-gated change plan, presenting the full list of updates and suspected derived fields like YoY for your review before any edits occur.

Presentation deck numbers show inconsistencies after a manual financial data refresh because manually editing labels without updating chart data sources leaves embedded numbers, footnotes, and derived fields like YoY out of sync with the main text.
