Hello,
Thank you for sharing your file with us via email, we promise to keep your documents confidential.
I converted your Word document with our latest
Spire.Office Platinum(Hotfix) Version:6.10.3, but I didn’t reproduce your issue. If you were not using the latest version, I suggest that you first try this one again. If the issue still exists after trying, to further investigate it, please share us with your system information (E.g. Windows 7, 64-bit), your region setting (E.g. China, Chinese) and your application target framework (E.g. Net Framework 4.8 ).
Sincerely,
Lisa
