When I try to upgrade some files from doc to docx, I run into an issue that squishes all the text onto one line on top of one another. See attachment for an example.
I'm currently using Spire.Doc verison 5.5.31.4040 with the following code:
Spire.Doc.Document doc = new Spire.Doc.Document();
doc.LoadFromFile(fi.FullName, Spire.Doc.FileFormat.Doc);
newPath = fi.FullName.Replace(".doc", ".docx");
doc.SaveToFile(newPath, Spire.Doc.FileFormat.Docx);
Is there a different way I should be upgrading the file?
