@Rounak_Kumar1

Looks like dependency is not downloaded properly…try to uninstall them…go to %userprofile%/.nuger/packages and then delete the itext and bouncy castle package folders …and redownload them

Cheers

@Rounak_Kumar1

You deleted the only one and tried?

Try unpacking this and place it in the packages folder under .nuget
itext7.bouncy-castle-fips-adapter.zip (1.7 MB)

You can delete the existing folder with same name

cheers

Hi,

How about to use WordApplicationScope to read HTML then use SaveDocumentAsPDF
OR use UseExcelFile to read HTML then use SaveExcelFileAsPDF?
