Add Custom and Built-in Shapes to your JavaScript apps - Draw shapes, create interactions, and change them with data. Like Excel, SpreadJS 12 implements dozens of built-in shapes to add more detail and visual appeal to your workbooks, as well as the ability to seamlessly import and export Excel workbooks that contain shapes. These 60+ shapes include basic rectangles, arrows, balloons, and action buttons.
Include different formatting in a single cell with rich text formatting - With rich text formatting, users can now add bold, italics, font, and all basic formatting to a single cell.
Spread Web Designer includes a rich text editor - In addition to offering more flexibility in visual styles, the rich text editor allows you to more clearly display mathematic, chemistry, and scientific formulas that require superscripts, subscripts, or symbols.
Animated charts - SpreadJS column, bar, line, and pie chart now include seamless loading and updating animation. When the data for a chart changes or the chart is first loaded, the chart will animate up to the values for the chart.
New Charts: Radar, Sunburst, and Treemap Charts - These new charts (also available in Excel) have full Spread Web Designer support, and you'll be able to seamlessly import and export Excel files that include these charts.
Excel-like Precision Selection - Excel's new feature allows users to select a large range, and then deselect specific cells. SpreadJS has added this as a feature.
Barcode sparklines - Barcode sparklines are implemented as a rendered formula, and can be used in order forms, for tracking purposes, and as website links (QR Codes).
