timelines

An open-source framework for transforming Google Sheets into interactive, media-rich chronological narratives.

TimelineJS streamlines complex storytelling by mapping data points from a standardized spreadsheet onto a responsive visual interface. It supports 20+ external media types (including YouTube, Google Maps, and Wikipedia) to provide context for historical or project-based sequences. Used by major outlets like CNN and Time, the tool handles the heavy lifting of scale and navigation so creators can focus on the narrative arc.
