Size error when converting to Excel pdf

The original document is 4 mb in size. But when the document is uploaded to the system and converted to pdf, the size is 33 mb.
I attached the original file and corrupted file. We are using Aspose.Excell 19.1.5 version. Thanks.
YG7915.zip (4.8 MB)

        // Set minimum size
        pdfSaveOptions.OptimizationType = PdfOptimizationType.MinimumSize;
