27 Aug 20261 minute to read

If you receive a “The file format you have selected isn’t supported. Please choose a valid format.” message when opening a document in the Angular DOCX Editor (Document Editor) , it typically indicates that the document format is not supported by the current version of the DOCX Editor. Here are some common reasons for this warning:

  1. Unsupported File Format: The document you are trying to open might be in a format that the DOCX Editor does not support. Ensure you are using a supported format, such as SFDT.
  2. Corrupted Document: The document file might be corrupted or improperly formatted. Try opening a different document to see if the issue persists.

To avoid this warning, always use the recommended document formats and features supported by the DOCX Editor.

DOCX Editor supports the following file formats:

  • Word Document (*.docx)
  • Syncfusion Document Text (*.sfdt)
  • Plain Text (*.txt)
  • Word Template (*.dotx)
  • HyperText Markup Language (*.html)
  • Rich Text Format (*.rtf)
  • Word XML Document (*.xml)
  • Word 97-2003 Template (*.dot)
  • Word 97-2003 Document (*.doc)

By using these supported formats, you can ensure compatibility and avoid unsupported warning messages when opening documents in the DOCX Editor.
