Run any tool on your spreadsheet — free.
Let your agent work across all your spreadsheets for you — one file or a whole folder of them.
Upload a workbook, pick any of the file-based tools our API exposes — describe, convert, validate, clean, aggregate, and more — fill in the options it needs, and run it. This is the exact same tool an AI agent calls over our API; the page just fills in the parameters for you. Your original workbook is never changed or stored.
How it works
The plain-language pages on this site each do one job. This page is the technical backstop: it lists every file-based tool the server exposes, reads that tool’s own input definition, and builds the form for you. Upload your file, choose a tool, fill in any options, and run it — you get exactly what an AI agent would get calling the same tool directly.
A web visitor is an API user
Each tool here hits the same API route an MCP client uses. The page turns your choices into the request the tool expects and shows the result verbatim — text output inline, and a download when the tool produces a new file. There is no separate “web” behaviour to diverge from the API.
What’s covered
Any tool that reads a single uploaded workbook is available — reading, describing, converting, validating, cleaning, aggregating, sorting, and the rest. Tools that need two files, a saved session, or a secret token to post to an outside service aren’t here, because those don’t fit a “run this against my one file” form.
Your original file is safe
The tool reads your file in memory to run, then discards it. Your uploaded .xlsx is never
changed and never stored — tools that transform your data hand back a new file to download,
leaving your original untouched.
Want these inside your AI agent, on your own machine, with no upload at all? Install xlsx-for-ai and ask Claude or Cursor to run any of these tools on your spreadsheet.
