Docx file is read and saved, The paragraphs of the file change

123.docx (10.7 KB)
Document doc = new Document(fileName);
doc.Save(fileName);

@gzd163 I was unable to reproduce the issue you mentioned with the attached “123.docx”. Input and output docx documents are displayed identically in my case.
Could you please send a screenshot of wrong showing the paragraph change in your case?

8 pt increased between paragraphs

@gzd163 Judging by the screenshot, you are using not MS Word to view documents. Is this true? Please note that Aspose.Words mimics MS Word layout and behavior and cannot guarantee correct display in third-party editors.
