Convert your Parquet files to XLSX format for Microsoft Excel and Google Sheets. Files are processed locally in your browser.
How the Parquet to Excel conversion works
Drop a .parquet file, preview the parsed rows, and download an .xlsx workbook — decoded and written entirely in your browser. One sheet named Data, header row from the column names, ready for Excel, Google Sheets, LibreOffice, or Numbers. No Python, no add-ins, no upload.
How Parquet types land in Excel cells
BOOLEAN → TRUE / FALSE
INT32 / FLOAT / DOUBLE → number
INT64 → exact-digit text (Excel numbers are floats that corrupt big integers)
TIMESTAMP → ISO 8601 text, not an Excel date serial — no timezone or epoch surprises
NULL → empty cell
Large files and limits
Reads cap at the first 100,000 rows (well inside Excel's 1,048,576-row sheet limit); a notice appears when a file is truncated. For full conversions of larger files: pandas read_parquet().to_excel().
