Format and Modify Named Ranges with Node.js via C++
Format Ranges
Setting Background Color and Font Attributes to a Named Range
To apply formatting, define a Style object to specify the style settings and apply it to the Range object.
The following example shows how to set the solid fill color (shading color) with font settings to a range.
const path = require("path");
const AsposeCells = require("aspose.cells.node");
// The path to the documents directory.
const dataDir = path.join(__dirname, "data");
// Instantiate a new Workbook.
const workbook = new AsposeCells.Workbook();
// Get the first worksheet in the book.
const WS = workbook.getWorksheets().get(0);
// Create a range of cells.
const range = WS.getCells().createRange(1, 1, 1, 18);
// Name the range.
range.setName("MyRange");
// Declare a style object.
let stl;
// Create/add the style object.
stl = workbook.createStyle();
// Specify some Font settings.
stl.getFont().setName("Arial");
stl.getFont().setIsBold(true);
// Set the font text color
stl.getFont().setColor(AsposeCells.Color.Red);
// To Set the fill color of the range, you may use ForegroundColor with
// Solid Pattern setting.
stl.setForegroundColor(AsposeCells.Color.Yellow);
stl.setPattern(AsposeCells.BackgroundType.Solid);
// Create a StyleFlag object.
let flg = new AsposeCells.StyleFlag();
// Make the corresponding attributes ON.
flg.setFont(true);
flg.setCellShading(true);
// Apply the style to the range.
range.applyStyle(stl, flg);
// Save the excel file.
workbook.save(path.join(dataDir, "rangestyles.out.xls"));
Adding Borders to a Named Range
It is possible to add borders to a range of cells instead of just a single cell. The Range object provides a setOutlineBorder(BorderType, CellBorderType, CellsColor) method that takes the following parameters to add a border to the range of cells:
- Border type, the type of border, selected from the BorderType enumeration.
- Line style, the line style, selected from the CellBorderType enumeration.
- Color, the line color, selected from the Color enumeration.
The following example shows how to set an outline border to a range.
const path = require("path");
const AsposeCells = require("aspose.cells.node");
// The path to the documents directory.
const dataDir = path.join(__dirname, "data");
// Instantiating a Workbook object
const workbook = new AsposeCells.Workbook();
// Clears the worksheets
workbook.getWorksheets().clear();
// Adding a new worksheet to the Workbook object
workbook.getWorksheets().add();
// Obtaining the reference of the newly added worksheet by passing its sheet index
const worksheet = workbook.getWorksheets().get(0);
// Accessing the "A1" cell from the worksheet
const cell = worksheet.getCells().get("A1");
// Adding some value to the "A1" cell
cell.putValue("Hello World From Aspose");
// Creating a range of cells starting from "A1" cell to 3rd column in a row
const range = worksheet.getCells().createRange(0, 0, 1, 3);
// Adding a thick top border with blue line
range.setOutlineBorder(AsposeCells.BorderType.TopBorder, AsposeCells.CellBorderType.Thick, AsposeCells.Color.Blue);
// Adding a thick bottom border with blue line
range.setOutlineBorder(AsposeCells.BorderType.BottomBorder, AsposeCells.CellBorderType.Thick, AsposeCells.Color.Blue);
// Adding a thick left border with blue line
range.setOutlineBorder(AsposeCells.BorderType.LeftBorder, AsposeCells.CellBorderType.Thick, AsposeCells.Color.Blue);
// Adding a thick right border with blue line
range.setOutlineBorder(AsposeCells.BorderType.RightBorder, AsposeCells.CellBorderType.Thick, AsposeCells.Color.Blue);
// Saving the Excel file
workbook.save(path.join(dataDir, "book1.out.xls"));
The following example shows how to set borders around each cell in the range.
const path = require("path");
const AsposeCells = require("aspose.cells.node");
// The path to the documents directory.
const dataDir = path.join(__dirname, "data");
const filePath = path.join(dataDir, "sample.xlsx");
// Loads the workbook which contains hidden external links
const workbook = new AsposeCells.Workbook(filePath);
// Access the cells in the first worksheet.
const cells = workbook.getWorksheets().get(0).getCells();
// Create a range of cells.
const range = cells.createRange("A6", "P216");
// Declare style.
let stl;
// Create the style adding to the style collection.
stl = workbook.createStyle();
// Specify the font settings.
stl.getFont().setName("Arial");
stl.getFont().setIsBold(true);
stl.getFont().setColor(AsposeCells.Color.Blue);
// Set the borders
stl.getBorders().get(AsposeCells.BorderType.TopBorder).setLineStyle(AsposeCells.CellBorderType.Thin);
stl.getBorders().get(AsposeCells.BorderType.TopBorder).setColor(AsposeCells.Color.Blue);
stl.getBorders().get(AsposeCells.BorderType.LeftBorder).setLineStyle(AsposeCells.CellBorderType.Thin);
stl.getBorders().get(AsposeCells.BorderType.LeftBorder).setColor(AsposeCells.Color.Blue);
stl.getBorders().get(AsposeCells.BorderType.BottomBorder).setLineStyle(AsposeCells.CellBorderType.Thin);
stl.getBorders().get(AsposeCells.BorderType.BottomBorder).setColor(AsposeCells.Color.Blue);
stl.getBorders().get(AsposeCells.BorderType.RightBorder).setLineStyle(AsposeCells.CellBorderType.Thin);
stl.getBorders().get(AsposeCells.BorderType.RightBorder).setColor(AsposeCells.Color.Blue);
// Create StyleFlag object.
const flg = new AsposeCells.StyleFlag();
// Make the corresponding formatting attributes ON.
flg.setFont(true);
flg.setBorders(true);
// Apply the style with format settings to the range.
range.applyStyle(stl, flg);
// Save the excel file.
workbook.save(path.join(dataDir, "output.xls"));
Rename a Named Range
Aspose.Cells allows you to rename a named range for your needs. You may get the named range and rename it by using Name.getText() attribute. The following example shows how to rename a named range.
const path = require("path");
const AsposeCells = require("aspose.cells.node");
// The path to the documents directory.
const dataDir = path.join(__dirname, "data");
// Open an existing Excel file that has a (global) named range "TestRange" in it
const workbook = new AsposeCells.Workbook(path.join(dataDir, "book1_testrange.xls"));
// Get the first worksheet
const sheet = workbook.getWorksheets().get(0);
// Get the Cells of the sheet
const cells = sheet.getCells();
// Get the named range "MyRange"
const name = workbook.getWorksheets().getNames().get("TestRange");
// Rename it
name.setText("NewRange");
// Save the Excel file
workbook.save(path.join(dataDir, "RenamingRange.out.xlsx"));
Union of Ranges
Aspose.Cells provides Range.unionRang(Range) method to take the union for ranges; the method returns an [Array] object. The following example shows how to take union for ranges.
const path = require("path");
const AsposeCells = require("aspose.cells.node");
// The path to the documents directory.
const dataDir = path.join(__dirname, "data");
const filePath = path.join(dataDir, "book1.xls");
// Instantiate a workbook object.
// Open an existing excel file.
const workbook = new AsposeCells.Workbook(filePath);
// Get the named ranges.
const ranges = workbook.getWorksheets().getNamedRanges();
// Create a style object.
const style = workbook.createStyle();
// Set the shading color with solid pattern type.
style.setForegroundColor(AsposeCells.Color.Yellow);
style.setPattern(AsposeCells.BackgroundType.Solid);
// Create a styleflag object.
const flag = new AsposeCells.StyleFlag();
// Apply the cellshading.
flag.setCellShading(true);
// Creates an array list.
let al = [];
// Get the array list collection apply the union operation.
al = ranges[0].unionRanges([ranges[1]]);
// Define a range object.
let rng;
let frow, fcol, erow, ecol;
for (let i = 0; i < al.length; i++)
{
// Get a range.
rng = al[i];
frow = rng.getFirstRow();
fcol = rng.getFirstColumn();
erow = rng.getRowCount();
ecol = rng.getColumnCount();
// Apply the style to the range.
rng.applyStyle(style, flag);
}
// Save the excel file.
workbook.save(path.join(dataDir, "rngUnion.out.xls"));
Intersection of Ranges
Aspose.Cells provides the Range.intersect(Range) method to intersect two ranges. The method returns a Range object. To check whether a range intersects another range, use the Range.intersect(Range) method that returns a Boolean value. The following example shows how to intersect the ranges.
const path = require("path");
const AsposeCells = require("aspose.cells.node");
// The path to the documents directory.
const dataDir = path.join(__dirname, "data");
const filePath = path.join(dataDir, "book1.xls");
// Instantiate a workbook object.
// Open an existing excel file.
const workbook = new AsposeCells.Workbook(filePath);
// Get the named ranges.
const ranges = workbook.getWorksheets().getNamedRanges();
// Check whether the first range intersect the second range.
const isIntersect = ranges[0].isIntersect(ranges[1]);
// Create a style object.
const style = workbook.createStyle();
// Set the shading color with solid pattern type.
style.setForegroundColor(AsposeCells.Color.Yellow);
style.setPattern(AsposeCells.BackgroundType.Solid);
// Create a styleflag object.
const flag = new AsposeCells.StyleFlag();
// Apply the cell shading.
flag.setCellShading(true);
// If first range intersects second range.
if (isIntersect) {
// Create a range by getting the intersection.
const intersection = ranges[0].intersect(ranges[1]);
// Name the range.
intersection.setName("Intersection");
// Apply the style to the range.
intersection.applyStyle(style, flag);
}
// Save the excel file.
workbook.save(path.join(dataDir, "rngIntersection.out.xls"));
Merge Cells in the Named Range
Aspose.Cells provides the Range.merge() method to merge the cells in the range. The following example shows how to merge the individual cells of a named range.
const path = require("path");
const AsposeCells = require("aspose.cells.node");
// The path to the documents directory.
const dataDir = path.join(__dirname, "data");
// Instantiate a new Workbook.
const wb1 = new AsposeCells.Workbook();
// Get the first worksheet in the workbook.
const worksheet1 = wb1.getWorksheets().get(0);
// Create a range.
const mrange = worksheet1.getCells().createRange("A18", "J18");
// Name the range.
mrange.setName("Details");
// Merge the cells of the range.
mrange.merge();
// Get the range.
const range1 = wb1.getWorksheets().getRangeByName("Details");
// Define a style object.
const style = wb1.createStyle();
// Set the alignment.
style.setHorizontalAlignment(AsposeCells.TextAlignmentType.Center);
// Create a StyleFlag object.
const flag = new AsposeCells.StyleFlag();
// Make the relative style attribute ON.
flag.setHorizontalAlignment(true);
// Apply the style to the range.
range1.applyStyle(style, flag);
// Input data into range.
range1.get(0, 0).putValue("Aspose");
// Save the excel file.
wb1.save(path.join(dataDir, "mergingrange.out.xls"));
Remove a Named Range
Aspose.Cells provides the NameCollection.removeAt(number) method to erase the name of the range. To clear the contents of the range, use Cells.clearRange(CellArea) method. The following example shows how to remove a named range with its contents.
const AsposeCells = require("aspose.cells.node");
const path = require("path");
// The path to the documents directory.
const dataDir = path.join(__dirname, "data");
// Instantiate a new Workbook.
const workbook = new AsposeCells.Workbook();
// Get all the worksheets in the book.
const worksheets = workbook.getWorksheets();
// Get the first worksheet in the worksheets collection.
const worksheet = worksheets.get(0);
// Create a range of cells.
const range1 = worksheet.getCells().createRange("E12", "I12");
// Name the range.
range1.setName("MyRange");
// Set the outline border to the range.
range1.setOutlineBorder(AsposeCells.BorderType.TopBorder, AsposeCells.CellBorderType.Medium, new AsposeCells.Color(0, 0, 128));
range1.setOutlineBorder(AsposeCells.BorderType.BottomBorder, AsposeCells.CellBorderType.Medium, new AsposeCells.Color(0, 0, 128));
range1.setOutlineBorder(AsposeCells.BorderType.LeftBorder, AsposeCells.CellBorderType.Medium, new AsposeCells.Color(0, 0, 128));
range1.setOutlineBorder(AsposeCells.BorderType.RightBorder, AsposeCells.CellBorderType.Medium, new AsposeCells.Color(0, 0, 128));
// Input some data with some formattings into
// A few cells in the range.
range1.get(0, 0).putValue("Test");
range1.get(0, 4).putValue("123");
// Create another range of cells.
const range2 = worksheet.getCells().createRange("B3", "F3");
// Name the range.
range2.setName("testrange");
// Copy the first range into second range.
range2.copy(range1);
// Remove the previous named range (range1) with its contents.
worksheet.getCells().clearRange(11, 4, 11, 8);
worksheets.getNames().removeAt(0);
// Save the excel file.
workbook.save(path.join(dataDir, "copyranges.out.xls"));
