Claude for Excel vs Claude for Word (2026)

Claude for Excel

by Anthropic

Claude for Word

by Anthropic

Pros

• ✓Cell-level citations trace every explanation back to a specific cell, formula or tab, and assumptions can be changed while formula relationships stay intact.
• ✓Native Excel operations on request, including sorting, filtering, pivot table edits, conditional formatting and data validation dropdowns, plus connectors that Anthropic names as S&P Global, LSEG and Daloopa.
• ✓With a Claude account, one conversation spans Excel, PowerPoint, Word and Outlook, so a model can become a deck or a memo without re-explaining the data.

Limitations

• –Not included in Enterprise audit logs, and the add-in does not inherit custom data retention settings. Compliance API coverage exists for Enterprise organizations but is still labeled public beta.
• –Data tables and macro or VBA operations are unsupported, and Anthropic warns about prompt injection from untrusted spreadsheets. It does not run on Excel 2016 or 2019 perpetual licenses, iPad or Android.
• –Routing through Bedrock, Vertex AI, Foundry or an LLM gateway drops cross-app work, dictation and file uploads, and connectors and Skills are listed as coming soon there.

Pros

• ✓Reads the whole open document, including comments, tracked changes, footnotes, tables and bookmarks, and accesses only that document. For contract review that scope is the point rather than a limitation.
• ✓Tracked changes mode lands every edit as a revision in Word's own review pane. Claude can work through comment threads, editing the anchored text and replying with what it changed, and it summarizes counterparty redlines.
• ✓With a Claude account, one conversation spans Word, Excel, PowerPoint and Outlook, so a memo can draw on a workbook or an email thread without re-explaining the data. Enabled Skills apply in each app as the work moves.

Limitations

• –Not included in Enterprise audit logs, and the add-in does not inherit custom data retention settings. Compliance API coverage exists for Enterprise organizations but is still labeled public beta.
• –Anthropic does not recommend it for litigation filings, audit-critical documents or counterparty sends without human review, nor for replacing legal or financial judgment. It also warns about prompt injection from untrusted documents.
• –Routing through Bedrock, Vertex AI, Foundry or an LLM gateway drops cross-app work, dictation and file uploads, and connectors and Skills are listed as coming soon there. It does not run on Word 2016 or 2019 perpetual licenses, iPad or Android.
