  1. In Oracle Visual Builder Cloud Service (VBCS), you can read Excel files directly in the browser using JavaScript and libraries like SheetJS (xlsx.js). This allows you to parse .xlsx files into JSON for further processing in your app.

    Steps to Implement

    1. Add the XLSX Library Include the SheetJS library in your index.html header:

    <script src="https://cdnjs.cloudflare.com/ajax/libs/xlsx/0.16.0/xlsx.full.min.js"></script>
    Cóipeáilte!

    This avoids adding it as a project dependency and works directly in VBCS runtime.

    2. Add a File Picker to Your Page Drag and drop a File Picker component onto your page in VBCS.

    3. Handle File Selection Event Bind the FilePickerSelect event to a JavaScript function in your page module:

    PageModule.prototype.processFile = function (fileSet) {
    var file = fileSet[0];
    var reader = new FileReader();

    reader.onload = function (e) {
    var data = e.target.result;
    var workbook = XLSX.read(data, { type: 'binary' });

    workbook.SheetNames.forEach(function (sheetName) {
    var rowObjects = XLSX.utils.sheet_to_row_object_array(workbook.Sheets[sheetName]);
    console.log(rowObjects); // JSON array of rows
    });
    };

    reader.readAsBinaryString(file);
    };
