Gamma Migration Deep Dive

Current State

!npm list 2>/dev/null | head -10

Overview

Migrate presentation workflows from PowerPoint, Google Slides, Canva, or other platforms to Gamma's AI-powered generation. Gamma takes a fundamentally different approach -- instead of manually placing slides, you provide content and Gamma generates the presentation. Migration is about converting your content pipeline, not your slide files.

Prerequisites

• Gamma API access (Pro+ plan)
• Source presentations accessible for content extraction
• Node.js 18+ for migration scripts
• Completed gamma-install-auth setup

Migration Approaches

Approach	When to Use	Effort
Content extraction + regeneration	Lots of text-heavy presentations	Medium
Import via Gamma UI	One-off migration of key decks	Low
Template recreation	Repeatable presentation formats	Medium
Parallel operation	Gradual transition over time	Low

Key insight: You don't "import" slides into Gamma. You extract content from old presentations and regenerate them using Gamma's AI. This often produces better results than the originals.

Instructions

Step 1: Inventory Source Presentations

// scripts/inventory-presentations.ts
import { readdir, stat } from "node:fs/promises";
import { join, extname } from "node:path";

interface PresentationInfo {
  path: string;
  format: string;
  sizeMB: number;
  lastModified: Date;
}

async function (): <[]> {
   entries =  (dir, { :  });
   : [] = [];

   ( entry  entries) {
     ext = (entry).();
     ([, , , , ].(ext)) {
       fullPath = (dir, entry);
       info =  (fullPath);
      presentations.({
        : fullPath,
        : ext,
        : info. / ( * ),
        : info.,
      });
    }
  }

  .();
   byFormat = presentations.( {
    acc[p.] = (acc[p.] || ) + ;
     acc;
  }, {}  <, >);
  .(, byFormat);

   presentations;
}
