Convert XLS to XLSX, XLSB & CSV using C++

Try executing the below snippet to see how API works in your environment or check the GitHub Repository for other common usage scenarios.

// load the file to be converted
intrusive_ptr<IWorkbook> book
    = Factory::CreateIWorkbook(dir->StringAppend(new String("template.xls")));
// save in different formats
book->Save(dir->StringAppend(new String("output.xlsx")), SaveFormat_Xlsx);
book->Save(dir->StringAppend(new String("output.xlsb")), SaveFormat_Xlsb);
book->Save(dir->StringAppend(new String("output.csv")), SaveFormat_CSV);

Create a Custom Excel Chart with C++

// create a new workbook
intrusive_ptr<IWorkbook> workbook = Factory::CreateIWorkbook();

// get first worksheet which is created by default
intrusive_ptr<IWorksheet> worksheet = workbook->GetIWorksheets()->GetObjectByIndex(0);

// add sample data
worksheet->GetICells()->GetObjectByIndex(new String("A1"))->PutValue(50);
worksheet->GetICells()->GetObjectByIndex(new String("A2"))->PutValue(100);
worksheet->GetICells()->GetObjectByIndex(new String("A3"))->PutValue(150);
worksheet->GetICells()->GetObjectByIndex(new String("A4"))->PutValue(110);
worksheet->GetICells()->GetObjectByIndex(new String("B1"))->PutValue(260);
worksheet->GetICells()->GetObjectByIndex(new String("B2"))->PutValue(12);
worksheet->GetICells()->GetObjectByIndex(new String("B3"))->PutValue(50);
worksheet->GetICells()->GetObjectByIndex(new String("B4"))->PutValue(100);

// add a chart to the worksheet
int chartIndex
    = worksheet->GetICharts()->Add(Aspose::Cells::Charts::ChartType::ChartType_Column, 5, 0, 20, 8);

// access the instance of the newly added chart
intrusive_ptr<Aspose::Cells::Charts::IChart> chart
    = worksheet->GetICharts()->GetObjectByIndex(chartIndex);

// add SeriesCollection (chart data source) to the chart ranging from A1 to B4
chart->GetNISeries()->Add(new String("A1:B4"), true);

// set the chart type of 2nd NSeries to display as line chart
chart->GetNISeries()->GetObjectByIndex(1)->SetType(
    Aspose::Cells::Charts::ChartType::ChartType_Line);

// save the Excel file
workbook->Save(new String("output.xlsx")));
