Why Use ExploreMyData for Parquet to Excel

Native DuckDB Parquet Support

DuckDB reads Parquet natively with zero conversion overhead. Column metadata, row groups, and compression are handled automatically for fast loads.

No Upload Required

Your Parquet file stays on your device. No data is sent to any server. Everything runs locally in your browser using DuckDB WASM.

Preserves Column Types

Parquet types map directly to Excel types. Integers, floats, strings, timestamps, and booleans all carry over so formulas and sorting work correctly.

Transform Before Export

Filter rows, rename columns, add calculations, or aggregate data before converting. Shape the data exactly how you want it in Excel.

Free Forever

No sign-up, no trial, no watermarks. Convert as many Parquet files to Excel as you need, completely free.

DuckDB processes Parquet files efficiently using columnar reads. Files with millions of rows load quickly because only the needed columns and row groups are read.
