Parquet editor

Open a Parquet file and edit it in your browser — change cells, add or delete rows, rename or drop columns — then download a new Parquet. Files never upload.

What you can edit

• Edit individual cell values in a paginated table.
• Add new rows or delete existing ones.
• Rename columns or drop them entirely.

Saving your changes

Download a new Parquet file when you are done. Types are re-inferred on write, and you can choose a SNAPPY, UNCOMPRESSED, or GZIP codec.

Private by design

Every edit happens in browser memory; the file is never uploaded.
