How to convert Excel (XLSX) to CSV without breaking your data
CSV is the universal format for moving spreadsheet data into other tools. Convert an Excel file to CSV in your browser in seconds, without losing rows or encoding.
CSV is the lingua franca of data: databases, CRMs, analytics tools and nearly every programming language read it. If a spreadsheet needs to move into another system, converting the XLSX to CSV is usually the first step.
What the conversion keeps
Our Excel to CSV converter reads every sheet in your workbook and turns it into comma-separated text. Values keep their type where it matters, quoted fields stay quoted, and accented characters are preserved with UTF-8 encoding. The conversion runs entirely in your browser, so your spreadsheet never leaves your device.
Why CSV beats copying and pasting
- No formatting surprises. Copying from Excel can merge cells, truncate text and mangle numbers.
- Ready for any tool. Import the CSV into a database, a dashboard or a script as-is.
- Reproducible. A CSV is plain text you can inspect, diff and version.
When you want JSON instead
If the data is headed for an API or a JavaScript project, Excel to JSON converts each row into an object. You can also go the other way with CSV to JSON once you already have CSV.
Convert in seconds
- Open Excel to CSV.
- Drop your .xlsx file.
- Download the CSV or copy the table.
