What's new in Excel JavaScript API 1.13

  • 아티클

The ExcelApi 1.13 added a method to insert worksheets into a workbook from a Base64-encoded string and an event to detect workbook activation. It also increased support for formulas in ranges by adding APIs to track changes to formulas and locate a formula's direct dependent cells. Additionally, it expanded PivotTable support by adding PivotLayout APIs for alt text, style, and empty cell management.
