Embedded Excel Component

Embedded excel can be accessed using GetWorkBookStream return OpenXMLOffice.Spreadsheet Worksheet. Refer Worksheet section for more details

C#

Chart chart = powerPoint.AddSlide(PresentationConstants.SlideLayoutType.BLANK)
        .AddChart(CreateDataCellPayload(), new G.LineChartSetting());
using Stream stream = chart.GetWorkBookStream();
// Creating a new excel instance object from chart base source
// Note: Updating data directly in Excel will now reflect in PPT Chart graphic cache on open.
// Use Chart object data for embedding chart data and this handle for extending addition of data,logo,etc...
X.Excel excel = new(stream);
Worksheet worksheet = excel.GetWorkSheet("Sheet1");
worksheet.SetRow(12, 1, new DataCell[] {
new() {
  cellValue = "Added Additional Data To Chart",
  dataType = CellDataType.STRING
  }
}, new());
// Save Content after completion to the source stream
// Important OpenXML-Office components work with memory the source file/stream will not get replaced automatically
// You can save to same source to overwrite it or make a duplicate copy without disturbing the source
excel.SaveAs(chart.GetWorkBookStream());
