Anthropic today announced that Claude can now create and edit Microsoft Office files and PDFs directly inside Claude.ai and the desktop app. Users describe what they need or upload data, and Claude returns ready-to-use Excel spreadsheets, Word documents, PowerPoint decks, and PDFs — complete with working formulas, multiple sheets, and charts.

The feature works through a private, sandboxed computer environment where Claude writes and runs its own code to build the files, similar to the code interpreter approach used by other assistants. It is rolling out first as a preview to Max, Team, and Enterprise plan users; Pro users will gain access in the coming weeks. To enable the feature, users must turn on “Upgraded file creation and analysis” under Settings > Features > Experimental.

Anthropic warns that because the feature gives Claude internet access to install packages from public sources like npm or PyPI, there are risks: manipulated files or websites could trick Claude into running unsafe code or leaking sensitive data from prompts, projects, or connected services like Google Drive. The company advises monitoring sessions closely. The move positions Claude as a direct producer of finished business deliverables rather than just a conversational advisor — and puts a general-purpose code interpreter inside the consumer product, with the security tradeoffs that entails.
