Filtering the kind of data while loading the workbook from template file

Sometimes, you want to specify which kind of data should be loaded when building the workbook from the template file. Filtering loaded data can improve the performance for your special purpose, especially when using LightCells APIs. Please use the LoadOptions.LoadFilter property for this purpose.

The following sample code loads only shape objects while loading the workbook from the template file which you can download from the given link. The following screenshot shows the template file contents and also explains that the data in Red color and Yellow background will not be loaded because LoadOptions.LoadFilter property has been set to LoadDataFilterOptions.Shape

The following screenshot shows the output PDF which you can download from the given link. Here you can see, the data in Red color and Yellow background is not present but all shapes are there.

// For complete examples and data files, please go to https://github.com/aspose-cells/Aspose.Cells-for-.NET
//Source directory
string sourceDir = RunExamples.Get_SourceDirectory();

//Output directory
string outputDir = RunExamples.Get_OutputDirectory();

// Set the load options, we only want to load shapes and do not want to load data
LoadOptions loadOptions = new LoadOptions(LoadFormat.Xlsx);
loadOptions.LoadFilter = new LoadFilter(LoadDataFilterOptions.All & ~LoadDataFilterOptions.Chart);

// Create workbook object from sample excel file using load options
Workbook workbook = new Workbook(sourceDir + "sampleFilterChars.xlsx", loadOptions);

// Save the output in pdf format
workbook.Save(outputDir + "sampleFilterChars_out.pdf", SaveFormat.Pdf);
