Excel is the most common spreadsheet format, but Parquet is the standard for modern data pipelines. This converter bridges the gap. Data engineers use it to convert Excel exports into Parquet before loading into Snowflake, BigQuery, or Databricks — skipping the CSV step entirely. Analysts use it to compress large spreadsheets for archival or efficient querying. Since everything runs locally, it's safe for sensitive financial data, HR spreadsheets, or any file that shouldn't be uploaded to third-party services.
Yes, completely free with no limits. No sign-up or credit card required.
Both .xlsx (modern Excel) and .xls (legacy Excel) formats are supported.
Your data never leaves your browser. All conversion happens locally using WebAssembly. We never see, store, or transmit your files.
If your workbook has multiple sheets, a sheet selector dropdown appears in the toolbar. You can switch between sheets instantly — the data preview and download update automatically. The first non-empty sheet is selected automatically.
The output uses Snappy compression by default, which provides a good balance of file size and read speed. Snappy is supported by all major data tools.
The converter exports the calculated values, not the formulas themselves. What you see in Excel is what you get in Parquet.
