Sometimes. It depends on where you use Claude. Some Claude apps can make an .xlsx today, and Claude Desktop, Cursor and VS Code can get the same result with a server.
Claude.ai can create Excel files when code execution and file creation are on. In Claude Desktop, Cursor or VS Code, connect the Spreadsheet server: Claude then writes .xlsx and .csv files, reads existing spreadsheets by path, adds columns and converts formats.
What you get
orders_q3.xlsx, net sales by region
Computed from all 3,412 rows, largest first
| Region | PLN |
|---|---|
| Mazowieckie | 1,284,300 |
| 3 more regions | ... |
| Opolskie | 96,420 |
| Rows read | 3,412 |
Free to start. Spreadsheet Pro is $19 once. Free vs Pro
In Claude.ai with code execution and file creation turned on, Claude can create .xlsx files in a sandbox and give you a download. In Claude Desktop, Cursor and VS Code without a tool, it gives you CSV or table text to paste, and it can't open a spreadsheet on your disk.
The Spreadsheet server writes rows to .xlsx, .csv, .tsv or .json, reads and queries existing spreadsheets by path, adds computed columns and converts formats. Each change is a new file. The source isn't changed.
