Spreadsheet tools
Convert tables and data files without opening a spreadsheet program. Every tool processes your files in your browser.
Choosing a spreadsheet tool
- CSV ⇄ JSON Converter turns CSV tables into JSON and JSON records into CSV.
- Excel ⇄ CSV Converter writes each sheet of an XLSX workbook as CSV or JSON, and turns CSV files into Excel workbooks.
About data privacy
Spreadsheets often hold customer lists, prices and other private data. These tools read your files with your browser and write the result on your device, so there is no upload step. Large files are handled in a background worker so the page stays responsive.
