    const sheetName = "Sheet1";
    const rangeAddress = "A1:F8"; 
    const worksheet = context.workbook.worksheets.getItem(sheetName);

    range.load('cellCount');
    await context.sync();
    
    console.log(range.cellCount);
});

Queues up a command to load the specified properties of the object. You must call context.sync() before reading the properties.

        }): Excel.Range;

Parameters

Returns

Merge the range cells into one region in the worksheet.

Parameters

Returns

Remarks

[ API set: ExcelApi 1.2 ]

Examples

await Excel.run(async (context) => { 
    const sheetName = "Sheet1";
    const rangeAddress = "A1:C3";
    const range = context.workbook.worksheets.getItem(sheetName).getRange(rangeAddress);
    range.merge(true);
    await context.sync(); 
});

// Link to full sample: https://raw.githubusercontent.com/OfficeDev/office-js-snippets/prod/samples/excel/42-range/range-merged-ranges.yaml

await Excel.run(async (context) => {
  // Retrieve the worksheet and the table in that worksheet.
  const sheet = context.workbook.worksheets.getActiveWorksheet();
  const tableRange = sheet.getRange("B2:E6");

  // Create a merged range in the first row of the table.
  const chartTitle = tableRange.getRow(0);
  chartTitle.merge(true);

  // Format the merged range.
  chartTitle.format.horizontalAlignment = "Center";

  await context.sync();
});

Selects the specified range in the Excel UI.

select(): void;

Returns

Remarks

[ API set: ExcelApi 1.1 ]

Examples

await Excel.run(async (context) => {
    const sheetName = "Sheet1";
    const rangeAddress = "F5:F10"; 
    const range = context.workbook.worksheets.getItem(sheetName).getRange(rangeAddress);

Sets multiple properties of an object at the same time. You can pass either a plain object with the appropriate properties, or another API object of the same type.

set(properties: Interfaces.RangeUpdateData, options?: OfficeExtension.UpdateOptions): void;

Parameters

Returns

Sets multiple properties on the object at the same time, based on an existing loaded object.

set(properties: Excel.Range): void;

Parameters

Returns

Examples

// Link to full sample: https://raw.githubusercontent.com/OfficeDev/office-js-snippets/prod/samples/excel/90-scenarios/multiple-property-set.yaml

await Excel.run(async (context) => {
    const sheet = context.workbook.worksheets.getItem("Sample");

    const sourceRange = sheet.getRange("B2:E2");
    sourceRange.load("format/fill/color, format/font/name, format/font/color");
    await context.sync();

    // Set properties based on the loaded and synced 
    // source range.
    const targetRange = sheet.getRange("B7:E7");
    targetRange.set(sourceRange); 
    targetRange.format.autofitColumns();
    await context.sync();
});

Displays the card for an active cell if it has rich value content.

showCard(): void;

Returns

Remarks

[ API set: ExcelApi 1.7 ]

Overrides the JavaScript toJSON() method in order to provide more useful output when an API object is passed to JSON.stringify(). (JSON.stringify, in turn, calls the toJSON method of the object that is passed to it.) Whereas the original Excel.Range object is an API object, the toJSON method returns a plain JavaScript object (typed as Excel.Interfaces.RangeData) that contains shallow copies of any loaded child properties from the original object.

toJSON(): Excel.Interfaces.RangeData;

Returns

Track the object for automatic adjustment based on surrounding changes in the document. This call is a shorthand for context.trackedObjects.add(thisObject). If you're using this object across .sync calls and outside the sequential execution of a ".run" batch, and get an "InvalidObjectPath" error when setting a property or invoking a method on the object, you need to add the object to the tracked object collection when the object was first created.

track(): Excel.Range;

Returns

Unmerge the range cells into separate cells.

unmerge(): void;

Returns

Remarks

[ API set: ExcelApi 1.2 ]

Examples

await Excel.run(async (context) => { 
    const sheetName = "Sheet1";
    const rangeAddress = "A1:C3";
    const range = context.workbook.worksheets.getItem(sheetName).getRange(rangeAddress);
    range.unmerge();
    await context.sync(); 
});

Release the memory associated with this object, if it has previously been tracked. This call is shorthand for context.trackedObjects.remove(thisObject). Having many tracked objects slows down the host application, so please remember to free any objects you add, once you're done using them. You will need to call context.sync() before the memory release takes effect.

untrack(): Excel.Range;

Returns

Examples

await Excel.run(async (context) => {
    const largeRange = context.workbook.getSelectedRange();
    largeRange.load(["rowCount", "columnCount"]);
    await context.sync();

    for (let i = 0; i < largeRange.rowCount; i++) {
        for (let j = 0; j < largeRange.columnCount; j++) {
            const cell = largeRange.getCell(i, j);
            cell.values = [[i *j]];

            // Call untrack() to release the range from memory.
            cell.untrack();
        }
    }

    await context.sync();
});
