Estableciendo fórmula para rango con nombre
Al igual que la aplicación Excel, las APIs de Aspose.Cells proporcionan la capacidad de especificar una fórmula para un rango con nombre usando su propiedad Range.refersTo. Podría haber numerosos escenarios de usabilidad para esta función, algunos de los cuales se detallan a continuación.
Estableciendo una fórmula simple para rango con nombre
Una fórmula simple podría ser una referencia a otra celda en la misma (o diferente) hoja de cálculo. El siguiente ejemplo crea un rango con nombre en una nueva hoja de cálculo y establece su referencia a otra celda.
<!DOCTYPE html>
<html>
<head>
<title>Aspose.Cells Example</title>
</head>
<body>
<h1>Create Named 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, 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 () => {
// Create an instance of Workbook
const book = new Workbook();
// Get the WorksheetCollection
const worksheets = book.worksheets;
// Add a new Named Range with name "NewNamedRange"
const index = worksheets.names.add("NewNamedRange");
// Access the newly created Named Range
const name = worksheets.names.get(index);
// Set RefersTo property of the Named Range to a formula. Formula references another cell in the same worksheet
name.refersTo = "=Sheet1!$A$3";
// Set the formula in the cell A1 to the newly created Named Range
worksheets.get(0).cells.get("A1").formula = "NewNamedRange";
// Insert the value in cell A3 which is being referenced in the Named Range
worksheets.get(0).cells.get("A3").value = "This is the value of A3";
// Calculate formulas
book.calculateFormula();
// Save the result in XLSX format
const outputData = book.save(SaveFormat.Xlsx);
const blob = new Blob([outputData]);
const downloadLink = document.getElementById('downloadLink');
downloadLink.href = URL.createObjectURL(blob);
downloadLink.download = 'output_out.xlsx';
downloadLink.style.display = 'block';
downloadLink.textContent = 'Download Excel File';
document.getElementById('result').innerHTML = '<p style="color: green;">Workbook created and saved. Click the download link to get the file.</p>';
});
</script>

Estableciendo una fórmula compleja para rango con nombre
Una fórmula compleja podría ser cualquier cosa, como un rango dinámico o una fórmula que abarca múltiples celdas en diferentes hojas de cálculo. El siguiente ejemplo crea un rango dinámico utilizando la función INDEX para obtener el valor de una lista según su ubicación.

}).then(() => {

});
document.getElementById('runExample').addEventListener('click', async () => {
const fileInput = document.getElementById('fileInput');
const result = document.getElementById('result');
const downloadLink = document.getElementById('downloadLink');
if (!fileInput.files.length) {
// If no file selected, we'll create a new workbook (mirrors JavaScript creating a new Workbook)
}
// Load workbook from file if provided, otherwise create a new empty workbook
let book;
if (fileInput.files.length) {
const file = fileInput.files[0];
const arrayBuffer = await file.arrayBuffer();
book = new Workbook(new Uint8Array(arrayBuffer));
} else {
book = new Workbook();
}
// Get the WorksheetCollection
const worksheets = book.worksheets;
// Add a new Named Range with name "data"
let index = worksheets.names.count;
worksheets.names.add("data");
// Access the newly created Named Range from the collection
const data = worksheets.names.get(index);
// Set RefersTo property of the Named Range to a cell range in same worksheet
data.refersTo = "=Sheet1!$A$1:$A$10";
// Add another Named Range with name "range"
index = worksheets.names.count;
worksheets.names.add("range");
// Access the newly created Named Range from the collection
const range = worksheets.names.get(index);
// Set RefersTo property to a formula using the Named Range data
range.refersTo = "=INDEX(data,Sheet1!$A$1,1):INDEX(data,Sheet1!$A$1,9)";
// Save the workbook
const outputData = book.save(SaveFormat.Xlsx);
const blob = new Blob([outputData]);
downloadLink.href = URL.createObjectURL(blob);
downloadLink.download = 'output_out.xlsx';

downloadLink.textContent = 'Download Modified Excel File';
result.innerHTML = '<p style="color: green;">Named ranges added successfully! Click the download link to get the modified file.</p>';

Aquí hay otro ejemplo que utiliza un rango con nombre para sumar valores de 2 celdas en diferentes hojas de cálculo.
