Claude in Excel & PowerPoint. Is it worth it? What works and what doesn't. Plus a Python perspective
Published: February 8, 2026
I came to evaluate its Python-in-Excel capabilities. But what I started to use more is its Excel & PowerPoint (PP) heavy lifting. That is where the biggest value is. The Python sandbox is a bonus. The heavy lift for the attached deck was done by Claudes sitting in Excel and PowerPoint saving me many hours of manual labor and much pain.
Fast points
It pretty much does all your Excel work - analysis, pivots, formulas, stats, cuts, distros, scenarios etc etc ... does it fast. With nicely formatted outputs by default. Same with PowerPoint
Reads images + Web search - formatted tables and charts.
Bonus: you get Python power of analysis, charts, stats & ML.
Python available in PowerPoint also. Useful for direct Python - PP
Biggest value is in its 'human like' and intelligent Excel working, allowing you to focus on results (and validations).
Is it worth it? Yes. Starts at $20. Plus you get Claude Code bundled. Your Excel and PowerPoint productivity impact is in multiples not percentages.
Top Tip : Use voice dictation. 3x faster than typing - from Boris Cherny, creator of Claude Code (link below for his top tips). Win+H on windows & Fn Twice on Mac.
For more details see attached document and my previous posts. Some key highlights below.

Python side useful stuff
Upload CSVs into Pandas, run statistical tests, forecasts, regressions, ML models (work well for smaller/ cleaner datasets), advanced charts. Upload and process Excel files, PPTs, PDFs, JSONs.
Python side Limitations
Sandbox is isolated - no API calls, no external databases, can't write to local drive. Files created inside the sandbox cannot come out (except images - see doc). 30MB upload limit. Many libraries installed but not all fully usable. Non-deterministic - same prompt may give different results. No automation possible. Data goes to Anthropic servers (there are nuances - see previous posts below)
How does this compare with xlwings Lite?
I covered that in detail in my previous posts (links below). They are different tools for different jobs.
xlwings Lite: full Python environment sitting inside Excel.
Claude in Excel: Intelligent AI assistant with very useful Python powers.
xlwings Lite: Do automations, tools and full stack Excel apps.
Claude: Do all your Excel work
xlwings Lite: Python power.
Claude: AI power
