Convert your Excel file to CSV — free.
Upload a spreadsheet and get a clean .csv back — every value from your sheet,
as a plain text file any system can read. Nothing is added, nothing is reformatted, and your original
workbook is never changed.
What you get
CSV — comma-separated values — is the most portable spreadsheet format there is. Almost every tool, database, and programming language can read it: accounting software, CRMs, data-import wizards, and any AI agent. This converter takes your Excel sheet and writes each row and cell out exactly as it is.
One sheet per CSV
A CSV file holds a single table, so we convert the first sheet in your workbook. If your file has more than one sheet, we’ll tell you which ones we left out — convert them one at a time by moving the sheet you need to the front, or reach for the full toolset below.
How it works
The page runs the same conversion your AI agent would call through our tools. It reads your file in
memory and never stores it — your original .xlsx is untouched; you just get a new CSV to
download.
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 “convert this workbook to CSV.”
