Convert Excel spreadsheets to CSV or JSON
Open .xlsx, .xls, .xlsb and .ods files right in your browser, preview each sheet, and export it as CSV (with the delimiter of your choice), TSV or JSON — or download every sheet at once as a ZIP of CSV files. Powered by SheetJS, so formulas show their calculated values and dates are formatted as in Excel. Nothing is uploaded.
Which delimiter should I choose?
Use a comma for most tools and databases. Many European versions of Excel expect a semicolon because the comma is the decimal separator there. Tab-separated output pastes cleanly into spreadsheets.
