PDF to Excel conversion: unsupported text found in converted document using C#

Dear Support User,

I’m using some sample documents for Pdf to Excel conversions. After conversion, the converted excel output document has unsupported text. I tried multiple times, but the issue remains the same. I have attached both input & output for your reference. Kindly advise.

Hi Support Team,

Upon further investigation, it’s been observed that the issue is with the PDF. This is not a Groupdocs.Conversion for .NET issue. When you try to convert the source PDF with Adobe Acrobat Pro, the converted file has same square/font in the output. Also, when you open the pdf and try to copy/paste text from it, the result is the same (invalid font/square chars). So, definitely there is something wrong with this particular pdf. Maybe font or encoding, or both, but for sure it’s not a Conversion issue.

We are investigating this scenario. Your investigation ticket ID is CONVERSIONNET-4976.
