# Claude in Excel & PowerPoint. Is it worth it? What works and what doesn't. Plus a Python perspective

![Claude in Excel Evaluation](/images/blog/claudeInExcelEval.png)

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

1. 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

2. Reads images + Web search - formatted tables and charts.

3. Bonus: you get Python power of analysis, charts, stats & ML.

4. Python available in PowerPoint also. Useful for direct Python - PP

5. Biggest value is in its 'human like' and intelligent Excel working, allowing you to focus on results (and validations).

6. 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

Know the trade-offs, know the limitations, and pick the right tool.
