.docx as a first-class format. It reads and writes Word files with its own document engine, built for this purpose and not borrowed from a generic converter. It is strict about one rule: whenever something cannot be carried across exactly, you are told. Nothing is dropped silently.
Three ways to work with a Word file
Keep it as a Word file
The file stays a
.docx in the vault. The agent edits it in place. Its changes are written into the file as native Word tracked changes, in a new version, and everything else in the file is preserved.Open it in the editor
Import Word (.docx) converts it into an editor document for collaborative work, and Download as Word converts it back.
Work in Word itself
Open in Word and use the add-in. Saving sends new versions back to the vault.
What import preserves
What changes in translation
Every item below produces a plain-language notice when it applies to your file.The second trip is always clean
A simplification can only happen once. When a document has been imported and exported, taking it round again produces no further changes and no notices. Casa Conect’s tests enforce this. Documents do not degrade a little more with every exchange.What is refused outright
For security, some files are rejected with a clear message rather than opened:- Macro-enabled documents (
.docm), and any file containing a VBA project - Files that are not valid Word documents, or that contain malformed or dangerous XML
- Archive bombs: files that expand to an unreasonable size, or that contain an unreasonable number of parts
