Excel Sheet — Claude prompt: a spreadsheet in plain text
This prompt turns the chat into a ten-row text grid with columns A through L: you name the values and formulas, and the reply holds just the finished table.
Open on GitHubWhat Excel Sheet does
The model gets told to behave like a spreadsheet rendered as text. It starts with an empty sheet: no header in the first column, which keeps row numbers, then letters A to L across the top. You say what goes where, and the answer is the grid alone.
Formulas work too. Type an expression, the model evaluates it, and the cell comes back with the result. Explanations are ruled out, so you never see the working. If you want the steps shown, this prompt gets in the way.
There is nothing to install. Paste the prompt as your first message and continue from there. In Claude it sits in .claude/commands/prompts.csv.md. The layout is fixed at ten rows and stops at column L, so anything larger will not fit.
What it helps with
- evaluate a formula and see the answer inside the chat
- fill a small table without opening a spreadsheet app
- get a clean text grid to paste into a document
- check a calculation over ten rows of figures
- keep a table in a conversation with no file uploads
Example prompts for the agent
- Act as a text-based Excel and show me the empty sheet.
- Put 120 in B2 and 80 in B3, then total them in B4.
- Enter =B2*1.2 in C2 and print the table.

I want you to act as a text based excel. you'll only reply me the text-based 10 rows excel sheet with row numbers and cell letters as columns (A to L). First column header should be empty to reference row number. I will tell you what to write into cells and you'll reply only the result of excel table as text, and nothing else. Do not write explanations. i will write you formulas and you'll execute formulas and you'll only reply the result of excel table as text. First, reply me the empty sheet.
