24 Jan 2026

Anthropic has expanded access to its advanced AI tool, Claude, by integrating it into Microsoft Excel for Pro plan users.

The feature was previously limited to Max, Team, and Enterprise users during its beta phase.

Now, you can summon Claude into your spreadsheets and let it handle complex formulas or multi-tab setups.

Feature highlights

Claude makes Excel more user-friendly by allowing drag-and-drop of files without the risk of overwriting.

It also provides instant cell-level explanations and can fix common errors like #REF! or #VALUE!.

The tool preserves formulas when updating assumptions, supports longer sessions with auto-compaction, and works with both .xlsx and .xlsm files (size limits depend on your plan).

From January 24, 2026, Pro users can leverage Claude to expedite their financial tasks.

This includes editing across multiple sheets simultaneously, testing scenarios, building financial models from templates, creating pivot tables and charts quickly while maintaining a clean change log.

Advanced features and future plans
Tool capabilities

Launched as a research preview in October 2025, the Claude in Excel tool integrates Anthropic's Claude models directly into Microsoft Excel.

It is powered by Sonnet 4.5 and lets users query complex multi-tab workbooks, get cell-level citations for explanations, update assumptions without breaking formulas, debug errors, and build models from templates or uploaded files like 10-K reports.

Users can also generate pivot tables/charts, variance analysis data cleaning/ trend identification while keeping a log of changes.
