Open an .xlsx, .xls, .xlsb or .ods file, pick the sheet, and download it as CSV, with the values formatted as Excel shows them. Choose comma, semicolon or tab, and add a byte-order mark so Excel reopens accents correctly. The file never leaves your browser.

Each cell is written the way Excel displays it: a date formatted as 3/14/26 stays 3/14/26, 12% stays 12%, and formulas are written as their last calculated result. Hidden rows and columns are included, and a merged range keeps its value in the first cell only. CSV holds one sheet, so pick it from the list; to get every sheet, download them one at a time.
Excel in Germany, France and much of Europe expects semicolons, since the comma is the decimal mark there. Pick the separator the receiving program expects. "Add BOM" puts a UTF-8 byte-order mark at the start of the file: without it, Excel on Windows opens UTF-8 CSV as ANSI and shows é instead of é.
Once the rows are in shape, CSV to PDF and Excel to PDF print them as a table that fits the page. From code, the Shotmint API renders any HTML table: POST https://shotmint.creasework.com/v1/pdf with {"html": "<table>…</table>"} returns a PDF with the header repeated on every page, and /v1/screenshot with "selector": "table" returns a PNG of just the table (1 credit each; 25 free renders a month, then €5 for 2,000 that never expire). Scripts, AI agents and Make or Zapier can get a key with a bare POST https://shotmint.creasework.com/v1/keys/free.

Is my file uploaded? No. Parsing and conversion run in your browser (spreadsheets are read and written with SheetJS, loaded only when needed); this page sends nothing to a server, so it works for private data.
Can it convert the other way? Yes: every page reads CSV, JSON and spreadsheets, and the "Convert to" menu picks the output. Related: CSV to JSON, JSON to CSV, CSV to Excel, JSON to Excel, Excel to JSON, CSV to Markdown, Excel to Markdown, Markdown table to CSV.
