# Documents, Spreadsheets & Presentations — NanthAI Edge

Canonical page: `https://nanthai.tech/features/documents`

NanthAI Edge can create and refine Microsoft Office files from an ordinary chat. Document tools are included with Pro.

## Word documents

- Create structured DOCX reports, briefs, letters, proposals, and agreements.
- For focused edits to an existing DOCX, Edge can propose tracked changes for individual accept or reject review.
- A requested whole-document rewrite produces a new document version; it is not presented as tracked changes.

## Excel workbooks

- Create XLSX workbooks with multiple sheets, typed values, formulas, styles, and validation rules.
- Read bounded sheets and ranges from an uploaded workbook.
- Make targeted workbook edits while preserving unrelated workbook content; full-sheet replacement remains an explicit rebuild.

## PowerPoint presentations

- Create presentations containing 1–20 slides from a topic, source files, images, or a reference deck.
- Continue in the same chat to revise a slide or selected element.
- Export the current result as editable PPTX or PDF/print output on web, iOS, and Android.
- An imported PPTX is interpreted and rebuilt. Edge does not claim lossless editing of arbitrary existing PowerPoint packages.

## File workflow

Generated Office files appear as file cards in the conversation. Users can open or download them and attach them to later chats for continued work. Uploaded files, knowledge-base material, and cited research can be used as source context when requested.
