What's inside this Excel file? See inside, free.
Upload a spreadsheet and get a plain-language overview — how many sheets it has, what each column holds, and how full the data is. Nothing is changed; we only read what's inside and describe it back to you.
What you get
A quick map of the workbook so you know what you're dealing with before you open it. First, the sheets — how many there are, their names, and how big each one is. Then, for the main sheet, a column profile: the name of every column, the kind of data it holds (number, date, text), how many values are filled in, how many are blank, and a sample value.
Read-only by design
This tool never changes your file. It reads the workbook in memory, describes what it found, and discards it — nothing is saved and nothing is written back. It's the same overview your AI agent would get from our API, just rendered for you to read.
Want this inside your AI agent, on your own machine, with no upload at all? Install xlsx-for-ai and ask Claude or Cursor to “tell me what's inside this workbook.”
