Claude adds file and Office tools

Anthropic is pushing Claude out of the chat box and into the files people actually hand to coworkers. In the last few weeks, it added in-app file creation and editing to Claude and published official Microsoft Office add-ins for PowerPoint and Excel. (support.claude.com 1) (support.claude.com 2) (support.claude.com 3) The file change is simple but important: instead of getting a block of text and pasting it somewhere else, users can now ask Claude to produce documents directly inside Claude on web, desktop, and mobile. Anthropic’s help center says Claude can create reports with charts, Excel models with working formulas, and presentations generated from source documents. (support.claude.com) Anthropic’s pricing page now lists “create and edit files with code execution” as a core Claude capability across its product lineup. That shifts Claude closer to a workspace tool, where the output is a finished file instead of just an answer in a chat window. (claude.com) The mobile piece matters because phone assistants usually stop at drafting text, then force you back to a laptop for the real work. Anthropic’s March 2026 release notes say file features are now available in Claude for iPhone and Android on paid plans, so a document can be drafted and edited from the app itself. (support.claude.com) Then there is Microsoft Office, which is where a lot of office work still ends up before it is sent, reviewed, or presented. Anthropic now has official add-ins in Microsoft AppSource for both PowerPoint and Excel, so Claude can sit inside those programs instead of in a separate browser tab. (marketplace.microsoft.com 1) (marketplace.microsoft.com 2) In PowerPoint, Anthropic says Claude reads an existing deck’s layouts, fonts, colors, and slide masters before making changes. That is the difference between “write me a slide” and “edit this deck without breaking the template my company spent six months standardizing.” (marketplace.microsoft.com) Anthropic’s PowerPoint help page says the add-in is in beta research preview and available on Pro, Max, Team, and Enterprise plans. Microsoft’s Office listing says it works in PowerPoint on the web and in PowerPoint 2016 or later on Windows and Mac. (support.claude.com) (pages.store.office.com) In Excel, the pitch is less about pretty formatting and more about doing spreadsheet work where the numbers already live. Anthropic says Claude for Excel can analyze, edit, and create workbooks, and its help page says it now supports connectors to outside data tools including S&P Global, London Stock Exchange Group, Daloopa, PitchBook, Moody’s, and FactSet. (marketplace.microsoft.com) (support.claude.com) Microsoft’s Office listing says the Excel add-in works on Excel for the web and Excel 2016 or later on Windows and Mac. Anthropic says Claude for Excel is available across paid plans, which gives the company a path into finance and operations teams that already spend their day inside spreadsheets. (pages.store.office.com) (support.claude.com) The bigger pattern is that Anthropic is no longer treating Claude as a place you visit just to ask questions. Its current product pages bundle chat, files, connectors, mobile, and Office tools into one stack, which is how software starts trying to replace the whole “copy from AI, paste into work” routine.
