Chat with your data
Ask ChatGPT or Claude about the CSV, Excel and JSON files on your Mac or Windows PC. Find patterns and build reports without learning Python or pasting data into the chat.
Works in ChatGPT and Claude, on the web and on your phone. See how it works in ChatGPT or Claude.
Data analysis shouldn't take so much time and effort.
You have spreadsheets full of answers, but getting them out is painful. Excel struggles with large files. Pasting rows into a chat cuts the data short and gets you estimates instead of real numbers. Learning Python and Pandas takes weeks. So you either do it by hand, hire someone, or make decisions without the full picture.
Desktop Commander turns plain English into accurate data analysis.
Describe what you want to know. ChatGPT or Claude writes a Python script, runs it on your actual file, and reports back the results.
Work with large files
ChatGPT or Claude writes a Python script and runs it in your terminal, so the whole file gets processed, not just the part that fits in the chat.
Real calculations, not guesses
The numbers come from code that ran on the actual file, every row of it. No estimating, no summarizing, no truncated data.
Skip the Python learning curve
Describe what you want to know in plain words. ChatGPT or Claude writes and runs the code for you.
Here is what stands out in q4_sales.csv.
- •Read all 48,210 rows with a Python script, not a sample.
- •Revenue was up 12% on Q3. Three products drove most of the growth.
- •Saved a summary table and a chart as q4-growth.png next to the file.
Explore your data instantly
Understand what you're working with before diving deep.
Try this in ChatGPT or Claude:
"Analyze the sales data in Downloads/q4_sales.csv. Show me the columns, data types, and any obvious patterns"
Answer specific business questions
Get the numbers you need without writing formulas.
Try this in ChatGPT or Claude:
"From customers.xlsx in my Documents, show me which regions have the highest churn rate and break it down by plan type"
Automate recurring reports
Build analysis you can run again and again.
Try this in ChatGPT or Claude:
"Create a Python script that generates a weekly summary from my transaction logs with totals by category, the top 10 vendors, and a month-over-month comparison"
Why This Approach Is Different
Excel / Google Sheets
Slow and manual. Requires learning formulas, pivot tables, and navigating endless sheets.
Paste data into a chat
Context limits force you to cut the data down. The AI "summarizes" instead of calculating, and numbers can be made up.
Learn Python yourself
Weeks of tutorials before you're productive. Easy to make mistakes.
ChatGPT or Claude with Desktop Commander
Describe what you want. It writes Python, runs it on your actual file, and returns real results.
Works with the files where they are
Point ChatGPT or Claude at a file or a whole folder on your Mac or Windows PC. It opens the files directly, so there is nothing to attach and nothing to copy into the chat.
Real code, real calculations
Nothing is guessed. ChatGPT or Claude writes Python scripts that run actual computations. You can see the code, check the logic, and reuse it.
