Signature class supports saving of Spreadsheet signed documents with different output file types. Each document type has list of compatible saving type. These values are listed in enum SpreadsheetSaveFileFormat.

Here are the steps to save signed Spreadsheet document to different output type with GroupDocs.Signature:

• Create new instance of Signature class and pass source document path or stream as a constructor parameter.

• Instantiate required signature options.

• Instantiate the SpreadsheetSaveOptions object according to your requirements and specify FileFormat as one of predefined values from SpreadsheetSaveFileFormat.

• Call Sign method of Signature class instance and pass signatureoptions and SpreadsheetSaveOptions object to it.

Following example demonstrates how to save signed Spreadsheet document with different output type

using (Signature signature = new Signature("sample.xlsx"))
{
    // create QRCode option with predefined QRCode text
    QrCodeSignOptions signOptions = new QrCodeSignOptions("JohnSmith")
    {
        // setup QRCode encoding type
        EncodeType = QRCodeTypes.QR,
        // set signature position
        Left = 100,
        Top = 100
    };
    SpreadsheetSaveOptions saveOptions = new SpreadsheetSaveOptions()
    {
        FileFormat = SpreadsheetSaveFileFormat.Pdf,
        OverwriteExistingFiles = true
    };
    // sign document to file
    signature.Sign("SignedXlsx.pdf", signOptions, saveOptions);
}
