Parquet to Excel Converter

Excel cannot open a .parquet file directly - it is a columnar binary format, not a spreadsheet. Convert it first:

1. Upload your Parquet file with the file picker above.
2. Choose the Excel file format - XLSX for Excel 2007 and later, or XLS for the legacy Excel 97-2003 format.
3. Click "Run Conversion".
4. Download the spreadsheet and open it as you would any other workbook.

The column names from the Parquet file become the header row, and every record becomes a row underneath.

• No setup: reading a Parquet file normally means installing a coding environment or connecting a data platform. Here it takes an upload.
• Familiar tools: sort, filter, pivot and chart the data with the spreadsheet features you already know.
• Sharing with non-technical colleagues: stakeholders who would never open a Parquet file will happily open a spreadsheet.
• Quick sanity checks: eyeball an export before it goes into a report, a dashboard or another system.

Values are written into the cells exactly as they are stored in the Parquet file, with no reinterpretation on the way. That is deliberate: long identifiers do not get mangled into scientific notation, leading zeros survive, and dates are not rewritten into a different regional format behind your back.

If you then want a column treated as numbers or dates for calculations, convert it once inside your spreadsheet software - selecting the column and using its text-to-columns or value-conversion feature takes a couple of clicks and leaves you in control of the result.
