cruxdiff

Compare Parquet files

Diff two Parquet files, multi-part datasets or partitioned folders by key — decoded locally, never uploaded.

Open the comparison tool →

• Records matched by a key column, not by row order
• Multi-part datasets and Hive partitions read as one table
• Exact INT64 and DECIMAL values — nothing rounded

Or just open one file in the Parquet viewer →

cruxdiff runs 100% in your browser — your files are never uploaded, and it works offline.
