Impostazione della formula per il intervallo nominato
Come l’applicazione Excel, le API di Aspose.Cells consentono di specificare una formula per un intervallo nominato utilizzando la proprietà Range.refersTo. Ci sono numerosi scenari di usabilità per questa funzione, alcuni dei quali sono descritti di seguito.
Impostazione di una Simple Formula per Intervallo con Nome
Una formula semplice potrebbe essere un riferimento ad un’altra cella nella stessa (o diversa) cartella di lavoro. Nell’esempio seguente viene creato un intervallo con nome in un nuovo foglio di lavoro e si imposta il suo riferimento ad un’altra cella.

// 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>';
});

Impostazione di una Formula Complessa per Intervallo con Nome
Una formula complessa potrebbe essere qualsiasi cosa, come un intervallo dinamico o una formula che si estende su più celle in fogli di lavoro diversi. Nell’esempio seguente viene creato un intervallo dinamico utilizzando la funzione INDICE per ottenere il valore da un elenco in base alla sua posizione.

// 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

Ecco un altro esempio che utilizza un intervallo con nome per sommare i valori di 2 celle in fogli di lavoro diversi.
