To convert a diagram of the think-cell®1 software, you have several options. On the one hand, if the think-cell® software is not enabled, you can select a think-cell® diagram and convert it directly like a native PowerPoint® diagram. Or you can also convert all the diagrams of a slide or a whole presentation (via the "More" menu in the ribbon).
It should be noted that the function for converting think-cell® diagrams is still in a beta phase and will be further optimized over the next versions. In version 8.5 of empower® charts, among other things, the transfer of colors, percentages, hatches and broken Excel links were optimized.
