Aspose.Cells for .NET logo

We are pleased to announce the release of Aspose.Cells for .NET v17.12. There are quite a few useful enhancements included for HTML and PDF renderings. Moreover, you can now auto-populate data against Smart Markers to split to other sheets. Please check the release notes in order to get an idea about what is new and what has been enhanced or fixed with this revision of Aspose.Cells for .NET. You can also install Aspose for .NET APIs directly from NuGet repository.

Auto-Populate Smart Markers Data to Other Worksheets

While using the Smart Markers feature, you might need to auto-populate data to other worksheets when it too large to be handled in a single worksheet. For example, your data source has 1500000 records. Since the data is large, so you can paste your desired data set in the first worksheet while the rest of the records to the next worksheet. The following sample code uses a data source that has 21 records in total. We will show only 15 records in the first worksheet, then the rest of the records will be automatically moved to the second worksheet. Please note, the second worksheet should also have the same smart marker tag (as first) and you must call WorkbookDesigner.Process(sheetIndex, isPreserved) method for both sheets.

//Create employees data tableDataTable dt = new DataTable("Employees");
dt.Columns.Add("EmployeeID", typeof(int)); 
//Add rows inside the data tabledt.Rows.Add(1230);
dt.Rows.Add(1231);
dt.Rows.Add(1232);
dt.Rows.Add(1233);
dt.Rows.Add(1234);
dt.Rows.Add(1235);
dt.Rows.Add(1236);
dt.Rows.Add(1237);
dt.Rows.Add(1238);
dt.Rows.Add(1239);
dt.Rows.Add(1240);
dt.Rows.Add(1241);

dt.Rows.Add(1247);
dt.Rows.Add(1248);
dt.Rows.Add(1249);
dt.Rows.Add(1250); 
//Create data reader from data tableDataTableReader dtReader = dt.CreateDataReader(); 
//Create empty workbookWorkbook wb = new Workbook(); 
//Access first worksheet and add smart marker in cell 
A1Worksheet ws = wb.Worksheets[0];
ws.Cells["A1"].PutValue("&=Employees.EmployeeID"); 
//Add second worksheet and add smart marker in cell 
A1wb.Worksheets.Add();
ws = wb.Worksheets[1];
ws.Cells["A1"].PutValue("&=Employees.EmployeeID"); 
//Create workbook designer
WorkbookDesigner wd = new WorkbookDesigner(wb); 
//Set data source with data readerwd.SetDataSource("Employees", dtReader, 15); 
//Process smart marker tags in first and second worksheetwd.Process(0, false);wd.Process(1, false); 
//Save the workbookwb.Save("outputAutoPopulateSmartMarkerDataToOtherWorksheets.xlsx");

Export Worksheet CSS Separately in Output HTML

Aspose.Cells provides the feature to export worksheet CSS separately when you convert your Excel file to HTML file format.

For more detail on the feature, please see this article/document for your reference.

Implement Cell.FormulaLocal Similar to Excel VBA Range.FormulaLocal

Microsoft Excel formulas may have different names in different locales/regions or languages. For example, SUM function is called SUMME in German. Aspose.Cells cannot work with non-English function names. In Microsoft Excel VBA, there is Range.FormulaLocal property that returns the name of the function as per its language or region. Aspose.Cells also provides Cell.FormulaLocal property for this purpose. However, this property will only work when you will implement GlobalizationSettings.GetLocalFunctionName(string standardName) method. For more detail, please see this article.

Prefix Table Elements Styles with HtmlSaveOptions.TableCssId Property

Aspose.Cells allows you to prefix table elements styles with HtmlSaveOptions.TableCssId property. For more detail, please see this article.

Render Office Add-Ins while Converting Excel to PDF

Aspose.Cells now supports to render MS Office Add-ins (in Excel files) in the output PDF. You do not need to use any special method or property to render Office Add-Ins in the output PDF. For more detail, please see this article.
