Populate PowerPoint templates

Keep design ownership with your creative team while developers automate the content. Open an existing PowerPoint template, locate placeholder text, and replace it with customer, project, or reporting data while retaining the surrounding slide design and formatting.

Target regular slides, notes, master slides, or layout slides with case and whole-word controls.
Update content that spans multiple text parts or lines without rebuilding the slide.

Merge PowerPoint or specific slides

Combine every slide or clone selected slides into a destination presentation, with control over whether imported slides keep their original appearance or adopt the destination theme.

Merge multiple presentations into one file or bring across selected slides only as needed.
Retain the source design or apply the destination presentation’s theme and styles.
Automate batch assembly for proposals, reports, course packs, and presentation libraries.
