How to Convert XLSX to CSV
Extract raw table values from an Excel workbook into CSV for databases, scripts, and tools that cannot read XLSX.
Steps
- Open the XLSX to CSV converter on Format Convertly.
- Add the spreadsheet in the browser dropzone.
- Convert and download CSV (remember CSV is typically one sheet of values).
Tips
- Formulas become calculated values (or may need a values-only sheet first).
- Multiple sheets require separate CSVs.
- Check date formats — Excel serials sometimes surprise importers.
Why browser conversion
Device-specific tutorial farms often multiply the same conversion across Windows, Mac, iPhone, and Android. For most people, one private browser workflow is enough — no install, no third-party conversion queue.
