GroupDocs.Signature can authenticate the presence of specific signatures in a XLSX document. Node.js via Java developers can effortlessly enhance their applications by incorporating our verification features.
const signatureLib = require('@groupdocs/groupdocs.signature')
// Instantiate a Signature object with the document
const signature = new signatureLib.Signature('input.xlsx');
// Establish TextVerifyOptions to validate signatures that include specified text
const options = new signatureLib.TextVerifyOptions();
options.setText('signature');
options.setMatchType(signatureLib.TextMatchType.Contains);
// Execute the verification process for document signatures
const result = signature.verify(options);
// Interpret and assess the outcomes of the verification
if (result.isValid()) {
console.log('\nDocument was verified successfully!');
