Convert Worksheet to Image

This code demonstrates how to convert a worksheet into an image format, which can be useful for various application needs such as embedding it into a document or a web page.

//Create a new Workbook object
//Open a template excel file
Workbook book = new Workbook("Sheet to Image.xls");

//Get the first worksheet.
Worksheet sheet = book.Worksheets[0];

//Define ImageOrPrintOptions
ImageOrPrintOptions imgOptions = new ImageOrPrintOptions();

//Specify the image type
imgOptions.ImageType = ImageType.Jpeg;

//Render the sheet with respect to specified image/print options
SheetRender sr = new SheetRender(sheet, imgOptions);

//Render the image for the sheet
Bitmap bitmap = sr.ToImage(0);

//Save the image file
bitmap.Save("SheetImage.jpg");

Using Smart Markers with Custom Objects

This snippet shows how to use Aspose.Cells' Smart Markers feature with custom objects, which is great for dynamically generating reports in Excel.

//Instantiate the workbookdesigner object.
WorkbookDesigner report = new WorkbookDesigner();

//Get the first worksheet(default sheet) in the workbook.
Aspose.Cells.Worksheet w = report.Workbook.Worksheets[0];

//Input some markers to the cells.
w.Cells["A1"].PutValue("Test");
w.Cells["A2"].PutValue("&=MyProduct.Name");
w.Cells["B2"].PutValue("&=MyProduct.Age");

//Instantiate the list collection based on the custom class.
IList<MyProduct> list = new List<MyProduct>();

//Provide values for the markers using the custom class object.
list.Add(new MyProduct("Simon", 30));
list.Add(new MyProduct("Johnson", 33));

//Set the data source.
report.SetDataSource("MyProduct", list);

//Process the markers.
report.Process(false);

//Save the excel file.
report.Workbook.Save("Smart Marker Customobjects.xls");

Merging Cells in a Range

This example shows how to merge or unmerge a range of cells in a worksheet, which can be useful for formatting purposes or creating visually organized reports.

//Create a workbook
Workbook workbook = new Workbook();
Worksheet worksheet = workbook.Worksheets[0];

//Create a range
Range range = worksheet.Cells.CreateRange("A1", "D4");

//Merge cells
range.Merge();

//Unmerge cells (optional)
range.UnMerge();

//Save the workbook
workbook.Save("MergedCells.xlsx");

Adding Chart Titles and Customizing Gridlines

This snippet illustrates how to add a chart title and customize the appearance of gridlines, which allows developers to create well-designed and professional-looking charts.

//Create a new workbook.
Workbook workbook = new Workbook();
Worksheet worksheet = workbook.Worksheets[0];

//Adding a chart to the worksheet
int chartIndex = worksheet.Charts.Add(ChartType.Column, 5, 0, 15, 5);
Chart chart = worksheet.Charts[chartIndex];

//Setting the chart title.
chart.Title.Text = "Sales Chart";

//Hiding major gridlines.
chart.ValueAxis.MajorGridLines.IsVisible = false;

//Saving the Excel file
workbook.Save("ChartWithTitles.xlsx");

Setting and Refreshing Dynamic Array Formulas

This example shows how to write a modern Excel 365 dynamic array formula (FILTER) into a cell, refresh all dynamic array spill ranges, and recalculate the workbook. The same approach works for any modern dynamic array or Excel 365 function such as SORT, UNIQUE, SEQUENCE, RANDARRAY, DROP, HSTACK, LAMBDA, LET, MAP, and others. See the Dynamic Array Formulas documentation for details.

//Load a workbook containing source data
Workbook wb = new Workbook("dynamicArrayFormula.xlsx");
Worksheet ws = wb.Worksheets[0];

//Target cell for the dynamic array formula
Cell f16 = ws.Cells["F16"];

//Set the dynamic array formula (FILTER spills into neighboring cells)
f16.SetDynamicArrayFormula(
 "=FILTER(A2:C15,(A2:A15=F4)*(C2:C15=25),\"\")",
 new FormulaParseOptions(),
 false);

//Refresh dynamic array spill ranges before calculation
wb.RefreshDynamicArrayFormulas(true);

//Calculate and save
wb.CalculateFormula();
wb.Save("out.xlsx");
