Specifying Sort Warning While Sorting Data

Possible Usage Scenarios

Please consider this textual data i.e. {11, 111, 22}. This textual data is sorted because, in terms of text, 111 comes before 22. But, if you want to sort this data not as text but as numbers, then it will become {11, 22, 111} because numerically 111 comes after 22. Aspose.Cells for Node.js via C++ provides {0} property to deal with this issue. Please set this property true and your textual data will be sorted as numerical data. The following screenshot shows the sort warning shown by Microsoft Excel when textual data which looks like numerical data is sorted.

Sample Code

The following sample code illustrates the usage of DataSorter.setSortAsNumber property as explained earlier. Please check its sample Excel file and output Excel file for more help.

//For complete examples and data files, please go to https://github.com/aspose-cells/Aspose.Cells-for-.NET
const AsposeCells = require("aspose.cells.node");

//Create workbook.
var workbook = new AsposeCells.Workbook("sampleSortAsNumber.xlsx");

//Access first worksheet.
var worksheet = workbook.getWorksheets().get(0);
//Create your cell area.
var ca = AsposeCells.CellArea.createCellArea("A1", "A20");

//Create your sorter.
var sorter = workbook.getDataSorter();
//Find the index, since we want to sort by column A, so we should know the index for sorter.
var idx = AsposeCells.CellsHelper.columnNameToIndex("A");
//Add key in sorter, it will sort in Ascending order.
sorter.addKey(idx, AsposeCells.SortOrder.Ascending);

sorter.setSortAsNumber(true);
//Perform sort.
sorter.sort(worksheet.getCells(), ca);
//Save the output workbook.
workbook.save("outputSortAsNumber.xlsx");
