Frequently Asked Questions

✅ Does the DOCX Editor support editing and saving an existing DOCX file?

Yes. Existing DOCX documents can be opened, edited and saved as DOCX files in the DOCX Editor.

✅ Are document styles customizable in the DOCX Editor?

Yes. The DOCX Editor supports built-in and custom styles for document formatting, with programmatic APIs for managing document content and formatting.

✅ Is merging multiple Word documents supported directly in the editor?

The DOCX Editor is primarily an interactive document editing component. For workflows that combine or assemble multiple Word documents, use the server-side Syncfusion Word Library (DocIO) and load the resulting document into the editor.

✅ Which platforms are supported in the DOCX Editor?

The DOCX Editor SDK supports React, Angular, Blazor, JavaScript/TypeScript, Vue, ASP.NET Core, ASP.NET MVC, WPF, and UWP.

✅ Can an application support tables and images with the DOCX Editor?

Yes. An application can provide table creation and editing, cell merging, image insertion, and image resizing. Some advanced Word-specific table, image, and positioning properties have limitations.

✅ Does the DOCX Editor support adding headers and footers?

Yes. Headers and footers can be added and edited within document sections, including different content for first, odd, and even pages.

✅ Does the DOCX Editor require a server?

Not for every scenario. Supported editing operations can run without interactions. Server-side services are required for operations such as opening Word documents, paste with formatting, restricted editing, spell checking, and saving formats other than DOCX.

✅ Which file formats are supported in the DOCX Editor?

The DOCX Editor supports opening and editing DOCX, SFDT, and other Word formats (DOC, DOTX, DOT, RTF, HTML, TXT). Exporting to PDF and other formats requires Syncfusion’s document processing libraries (Word Library and PDF Library) for server-side conversion.
