QueryTable queryTable = workbook.getWorksheets().get(0).getQueryTables().addQueryTable(query, connectionString);

Data Manipulation

Once your data is loaded, you can manipulate it using Aspose.Cells for Java. Perform operations like sorting, filtering, and data transformation to prepare your data for analysis.

// Sort data by a specific column
worksheet.getCells().sort(0, true);

// Apply a filter to display specific data
AutoFilter autoFilter = worksheet.getAutoFilter();
autoFilter.setRange("A1:D1");

// Perform data transformation
// (e.g., converting currency, calculating percentages)

Creating Excel Charts

Now, let’s dive into the exciting part—creating Excel charts using your processed data. Aspose.Cells for Java provides a wide range of chart types, from simple bar charts to complex radar charts.

// Create a bar chart
int chartIndex = worksheet.getCharts().addChart(ChartType.BAR, 5, 1, 15, 5);
Chart chart = worksheet.getCharts().get(chartIndex);

// Add data series to the chart
chart.getNSeries().add("Sheet1!A1:A5", true);
chart.getNSeries().add("Sheet1!B1:B5", true);

// Customize the chart appearance
chart.getChartArea().getBorder().setVisible(false);
chart.setTitle("Sales Analysis");

Exporting the Excel File

After creating your Excel charts, you can export the workbook to a file format of your choice, such as XLSX or PDF.

workbook.save("data_analysis_report.xlsx", SaveFormat.XLSX);
