# Document input

Document input means uploaded text, word-processing, presentation, or spreadsheet content is available as model input. Supported formats and extraction fidelity are qualifiers.

- HTML: https://canmyagentuse.com/features/office-document-input
- JSON: https://canmyagentuse.com/api/v1/features/office-document-input.json
- Markdown: https://canmyagentuse.com/features/office-document-input.md

Terminology basis: **Common product term** — https://docs.x.ai/grok/faq.

## Current support at a glance

Document input: 7 supported, 1 partial, 0 unsupported, 23 unreviewed across 31 cataloged products.

- Reviewed current products: 8 of 31
- Supported: 7
- Partial: 1
- Unsupported: 0
- Unreviewed: 23
- Not applicable: 0

Unknown or unreviewed means insufficient published evidence; it does not mean unsupported.

This row covers common document attachments such as plain text, rich text, word-processing files, presentations, and spreadsheets. Evidence should list exact formats and distinguish plain-text extraction from retained tables, formulas, notes, comments, charts, images, layout, and workbook or slide structure.

Macros, external links, encrypted files, tracked changes, hidden sheets, and embedded objects are separate risk and fidelity boundaries. When a connector opens a cloud document by reference, record that path separately from a direct upload.
