Copy Ranges of Excel with JavaScript via C++

Introduction

In Excel, you can select a range, copy the range, then paste it with specific options to the same worksheet, other worksheets or other files.

Copy Ranges Using Aspose.Cells for JavaScript via C++

Aspose.Cells for JavaScript via C++ provides some overload Range.copy(Range, PasteOptions) methods to copy the range. And Range.copyStyle(Range) only the copy style of the range; Range.copyData(Range) only the copy value of the range.

Copy Range

Creating two ranges: the source range, the target range, then copying the source range to the target range with the Range.copy method.

See the following code:

<!DOCTYPE html>
<html>
    <head>
        <title>Aspose.Cells Example</title>
    </head>
    <body>
        <h1>Example Title</h1>
        <input type="file" id="fileInput" accept=".xls,.xlsx,.csv" />
        <button id="runExample">Run Example</button>
        <a id="downloadLink" style="display: none;">Download Result</a>
        <div id="result"></div>
    </body>

    <script src="aspose.cells.js.min.js"></script>
    <script type="text/javascript">
        const { Workbook, SaveFormat, Worksheet, Cell } = AsposeCells;
        
        AsposeCells.onReady({
            license: "/lic/aspose.cells.enc",
            fontPath: "/fonts/",
            fontList: [
                "arial.ttf",
                "NotoSansSC-Regular.ttf"
            ]
        }).then(() => {
            console.log("Aspose.Cells initialized");
        });

        document.getElementById('runExample').addEventListener('click', async () => {
            const fileInput = document.getElementById('fileInput');
            let workbook;
            if (fileInput.files.length) {
                const file = fileInput.files[0];
                const arrayBuffer = await file.arrayBuffer();
                workbook = new Workbook(new Uint8Array(arrayBuffer));
            } else {
                workbook = new Workbook();
            }

            // Get all the worksheets in the book.
            let worksheets = workbook.worksheets;

            // Get the first worksheet in the worksheets collection.
            let worksheet = workbook.worksheets.get(0);

            // Create a range of cells.
            let sourceRange = worksheet.cells.createRange("A1", "A2");

            // Input some data with some formattings into A few cells in the range.
            sourceRange.get(0, 0).value = "Test";
            sourceRange.get(1, 0).value = 123;

            // Create target range of cells.
            let targetRange = worksheet.cells.createRange("B1", "B2");

            // Copy source range to target range in the same worksheet 
            targetRange.copy(sourceRange);

            // Create target range of cells.
            workbook.worksheets.add();
            worksheet = workbook.worksheets.get(1);

            targetRange = worksheet.cells.createRange("A1", "A2");
            // Copy source range to target range in another worksheet 
            targetRange.copy(sourceRange);

            // Copy to another workbook
            const anotherWorkbook = new Workbook();

            worksheet = workbook.worksheets.get(0);

            targetRange = worksheet.cells.createRange("A1", "A2");
            // Copy source range to target range in another workbook 
            targetRange.copy(sourceRange);

            const outputData = workbook.save(SaveFormat.Xlsx);
            const blob = new Blob([outputData]);
            const downloadLink = document.getElementById('downloadLink');
            downloadLink.href = URL.createObjectURL(blob);
            downloadLink.download = 'output.xlsx';
            downloadLink.style.display = 'block';
            downloadLink.textContent = 'Download Modified Excel File';

            document.getElementById('result').innerHTML = '<p style="color: green;">Operation completed successfully!</p>';
        });
    </script>
</html>

Paste Range With Options

Aspose.Cells for JavaScript via C++ supports pasting the range with specific types.

<!DOCTYPE html>
<html>
    <head>
        <title>Aspose.Cells Paste Range Example</title>
    </head>
    <body>
        <h1>Paste Range Example</h1>
        <input type="file" id="fileInput" accept=".xls,.xlsx,.csv" />
        <button id="runExample">Run Example</button>
        <a id="downloadLink" style="display: none;">Download Result</a>
        <div id="result"></div>
    </body>

    <script src="aspose.cells.js.min.js"></script>
    <script type="text/javascript">
        const { Workbook, SaveFormat, PasteOptions, PasteType } = AsposeCells;
        
        AsposeCells.onReady({
            license: "/lic/aspose.cells.enc",
            fontPath: "/fonts/",
            fontList: [
                "arial.ttf",
                "NotoSansSC-Regular.ttf"
            ]
        }).then(() => {
            console.log("Aspose.Cells initialized");
        });

        document.getElementById('runExample').addEventListener('click', async () => {
            const fileInput = document.getElementById('fileInput');
            if (!fileInput.files.length) {
                document.getElementById('result').innerHTML = '<p style="color: red;">Please select an Excel file.</p>';
                return;
            }

            const file = fileInput.files[0];
            const arrayBuffer = await file.arrayBuffer();

            // Loads the workbook which contains hidden external links
            const workbook = new Workbook(new Uint8Array(arrayBuffer));

            // Get all the worksheets in the book.
            const worksheets = workbook.worksheets;

            // Get the first worksheet in the worksheets collection.
            const worksheet = workbook.worksheets.get(0);

            // Create a range of cells.
            const sourceRange = worksheet.cells.createRange("A1", "A2");

            // Input some data with some formattings into a few cells in the range.
            sourceRange.get(0, 0).value = "Test";
            sourceRange.get(1, 0).value = 123;

            // Create target range of cells.
            const targetRange = worksheet.cells.createRange("B1", "B2");

            // Init paste options.
            const options = new PasteOptions();
            // Set paste type.
            options.pasteType = PasteType.ValuesAndFormats;
            options.skipBlanks = true;

            // Copy source range to target range
            targetRange.copy(sourceRange, options);

            // Saving the modified Excel file
            const outputData = workbook.save(SaveFormat.Xlsx);
            const blob = new Blob([outputData]);
            const downloadLink = document.getElementById('downloadLink');
            downloadLink.href = URL.createObjectURL(blob);
            downloadLink.download = 'output.xlsx';
            downloadLink.style.display = 'block';
            downloadLink.textContent = 'Download Modified Excel File';

            document.getElementById('result').innerHTML = '<p style="color: green;">Range copied successfully! Click the download link to get the modified file.</p>';
        });
    </script>
</html>

Only Copy Data Of The Range

Also, you can copy the data with the Range.copyData method as shown in the following code:

<!DOCTYPE html>
<html>
    <head>
        <title>Aspose.Cells Example</title>
    </head>
    <body>
        <h1>Copy Range Example</h1>
        <input type="file" id="fileInput" accept=".xls,.xlsx,.csv" />
        <button id="runExample">Run Example</button>
        <a id="downloadLink" style="display: none;">Download Result</a>
        <div id="result"></div>
    </body>

    <script src="aspose.cells.js.min.js"></script>
    <script type="text/javascript">
        const { Workbook, SaveFormat } = AsposeCells;
        
        AsposeCells.onReady({
            license: "/lic/aspose.cells.enc",
            fontPath: "/fonts/",
            fontList: [
                "arial.ttf",
                "NotoSansSC-Regular.ttf"
            ]
        }).then(() => {
            console.log("Aspose.Cells initialized");
        });

        document.getElementById('runExample').addEventListener('click', async () => {
            const fileInput = document.getElementById('fileInput');
            if (!fileInput.files.length) {
                document.getElementById('result').innerHTML = '<p style="color: red;">Please select an Excel file.</p>';
                return;
            }

            const file = fileInput.files[0];
            const arrayBuffer = await file.arrayBuffer();

            // Instantiating a Workbook object from the uploaded file
            const workbook = new Workbook(new Uint8Array(arrayBuffer));

            // Get all the worksheets in the book.
            const worksheets = workbook.worksheets;

            // Get the first worksheet in the worksheets collection.
            const worksheet = worksheets.get(0);

            // Create a range of cells.
            const sourceRange = worksheet.cells.createRange("A1", "A2");

            // Input some data with some formattings into a few cells in the range.
            sourceRange.get(0, 0).value = "Test";
            sourceRange.get(1, 0).value = 123;

            // Create target range of cells.
            const targetRange = worksheet.cells.createRange("B1", "B2");

            // Copy the data of source range to target range
            targetRange.copyData(sourceRange);

            // Saving the modified Excel file
            const outputData = workbook.save(SaveFormat.Xlsx);
            const blob = new Blob([outputData]);
            const downloadLink = document.getElementById('downloadLink');
            downloadLink.href = URL.createObjectURL(blob);
            downloadLink.download = 'output.xlsx';
            downloadLink.style.display = 'block';
            downloadLink.textContent = 'Download Excel File';

            document.getElementById('result').innerHTML = '<p style="color: green;">Range copied successfully! Click the download link to get the modified file.</p>';
        });
    </script>
