Excel to Parquet

Convert an Excel workbook to Apache Parquet in your browser. The first sheet is used; types are inferred. Files never leave the page.

How it works

Drop an Excel workbook (.xlsx); the first sheet is read, column types are inferred, and the rows are written to Apache Parquet for download. No upload.

Compression options

Choose SNAPPY (the default — fast, balanced), UNCOMPRESSED, or GZIP (smaller files, slower) before converting.

Private by design

Conversion runs locally in your browser — there is no server and no upload.
