Think-Cell is one of the most used presentation add-in for Office in the world that lots of companies, especially consulting firms, use when going about doing their work. modernCharts is the new kid on the block that has a different service offering. The biggest difference is that modernCharts is an Excel add-in (for now) and Think-Cell is a PowerPoint add-in. The following table details the other difference and why we think both tools can coexist.
