Converting from XLSX to PDF the PDF is empty

[Tigerhawk007]

I have a C# app that generates an Excel file, but I also need it is PDF format. When using MiniPdf.ConvertToPdf it creates the PDF but it is only one page and is blank. I also tried converting the same Excel file using the web page demo and it did the same thing.

Regards,
Aaron

Just noticed that you have a 0.30 version, so I'm updating that to see if that resolves my issue.

Updating didn't seem to make a difference. From my code it is still creating a 1 kb single blank page PDF. Below is how I have it implemented.

    internal static void ExcelToPDF(AppSettings appSettings, string xlFname, ref Logging log)
    {

        string pdfName = xlFname.Replace("xlsx", "pdf");
        MiniPdf.ConvertToPdf(xlFname, pdfName);

I verified this again with the file you uploaded.

using MiniSoftware;

var xlFname = Path.GetFullPath(args.Length > 0 ? args[0] : @"..\..\tests\Issue_Files\xlsx\XlsxIssue75.xlsx");
var pdfName = xlFname.Replace("xlsx", "pdf");

MiniPdf.ConvertToPdf(xlFname, pdfName);

var pdfInfo = new FileInfo(pdfName);
Console.WriteLine(pdfInfo.FullName);
Console.WriteLine(pdfInfo.Length);

Could you please confirm that the XLSX file is fully saved and closed before calling MiniPdf.ConvertToPdf? If the Excel file is generated in the same process, please make sure the workbook/package/stream is disposed or closed before conversion.

Or you can provide project zip
