Get Validation Applied on a Cell

You can use Aspose.Cells for Node.js to get the validation applied to a cell. Aspose.Cells provides the Cell.getValidation() method for this purpose. If there is no validation applied on the cell, it returns null.

Similarly, you can use Worksheet.validations.getValidationInCell(number, number) method to acquire the validation applied to a cell by providing its row and column indices.

Node.js code to get the validation applied on a Cell

Below code sample shows you how to get validation applied on a cell.

const AsposeCells = require("aspose.cells.node");
const path = require("path");

// The path to the documents directory.
const dataDir = path.join(__dirname, "data");

// Instantiate the workbook from sample Excel file
const workbook = new AsposeCells.Workbook(dataDir + "sample.xlsx");

// Access its first worksheet
const worksheet = workbook.getWorksheets().get(0);

// Cell C1 has the Decimal Validation applied on it. It can take only the values Between 10 and 20
const cell = worksheet.getCells().get("C1");

// Access the validation applied on this cell
const validation = cell.getValidation();

// Read various properties of the validation
console.log("Reading Properties of Validation");
console.log("--------------------------------");
console.log("Type: " + validation.getType());
console.log("Operator: " + validation.getOperator());
console.log("Formula1: " + validation.getFormula1());
console.log("Formula2: " + validation.getFormula2());
console.log("Ignore blank: " + validation.getIgnoreBlank());
