Merge Multiple Google Docs™ into One Document
Combine selected content from up to five Google Docs into one new document, with explicit ordering, style-master, and processing choices.
Merge Documents Wizard combines content from several Google Docs into one continuous output document. Choose up to five sources, control their order, and select the tabs to include from each file.
The wizard never edits the source documents. It creates a new Google Doc and uses the first source as the style master for page layout, headers, footers, and base styles.
Google Docs™ only
Open Merge Documents Wizard from Document Tools in the Google Docs add-on. The output combines all selected content into one continuous document.

Choose and order the sources
- 1Open Merge Documents Wizard and choose whether to include the Google Doc you currently have open.

- 5Expand each source and select the tabs to include. Use Select All when you need the complete document.
How the processing route is chosen
Swipe sideways to see all columns
| Selection | Route | What to expect |
|---|---|---|
| Every tab from one source document | Recommended merge | Combines the complete source without reconstructing it tab by tab. You can still switch to Detailed merge. |
| Multiple source documents or selected tabs | Detailed merge | Reconstructs the selected content in source order and can take longer for large or complex files. |
Most multi-document jobs use Detailed merge
The recommended route applies only when the selection is one complete source document. Adding another source or excluding tabs uses detailed processing automatically.
Create the merged document
- 1Review the selected tabs and the document order, then continue to Configure Merge Options.
- 2Check whether the summary says Recommended merge or Detailed merge.
- 3Enter a title for the new document.
- 4For Detailed merge, optionally add a Heading Styles Legend for manual heading-theme cleanup.
- 5Click Merge, wait for processing to finish, then open and review the new document from the success screen.
Output and detailed-merge limitations
- All selected content is combined into one continuous output document; source tab structures are not recreated.
- The original documents remain unchanged.
- Comments, suggestions, revision history, bookmarks, protected ranges, smart chips, AI summaries, and e-signature fields are not copied by detailed processing.
- Table of contents elements can be skipped, and checkboxes can become standard list items.
- If a detailed merge stops after creating the output file, the error screen can link to the partial document. Review it before retrying with fewer sources or tabs.
Start with a small merge
Test two short source documents first when layout fidelity matters. Check headings, tables, lists, and spacing before running a larger job.
