Word and Google Docs

Install OfficeIMO.Word.GoogleDocs. Build the plan before acquiring credentials when you need a review or strict fidelity gate.

using OfficeIMO.GoogleWorkspace;
using OfficeIMO.Word;
using OfficeIMO.Word.GoogleDocs;

using WordDocument document = WordDocument.Create();
document.AddParagraph("Quarterly review").SetStyle(WordParagraphStyles.Heading1);
document.AddParagraph("Results and next steps.");

var options = new GoogleDocsSaveOptions {
    Title = "Quarterly review",
    Tabs = new GoogleDocsTabOptions { Strategy = GoogleDocsTabStrategy.FirstTab },
    Comments = GoogleDocsCommentMode.UnanchoredDriveComments
};
GoogleDocsTranslationPlan plan = document.BuildGoogleDocsPlan(options);
GoogleDocumentReference created = await document.ExportToGoogleDocsAsync(session, options);

For a safe replacement, native-import the target and pass the observed revision:

GoogleDocsImportResult current = await session.ImportGoogleDocAsync(
    "document-id",
    new GoogleDocsImportOptions { Mode = GoogleDocsImportMode.Native });

using (current.Document) {
    var replace = new GoogleDocsSaveOptions {
        Location = new GoogleDriveFileLocation { ExistingFileId = current.Source.FileId },
        Replace = new GoogleDocsReplaceOptions { ExpectedRevisionId = current.Source.RevisionId },
        Tabs = new GoogleDocsTabOptions { Strategy = GoogleDocsTabStrategy.ReplaceEveryTab }
    };
    await document.ExportToGoogleDocsAsync(session, replace);
}

FirstTab, SelectedTab, and ReplaceEveryTab are explicit. Existing replacement cleans the selected scope, including stale header/footer and named-range structures. OverwriteLatest and target-revision merge are deliberate alternatives; neither is silently selected.

Native import projects supported tabs, body content, styles, lists, tables, links, and images. DriveExport converts to DOCX and loads through OfficeIMO.Word when broader Word fidelity matters. Word comments can become unanchored Drive comments because Google editors do not expose an equivalent custom anchor contract.
