Parquet Editor од Shipit Software

Open a local Parquet file in a full browser tab. Inspect rows and schema, search and sort table values, edit supported cells, undo changes and download an edited Parquet copy. Run SQL against the complete original file using bundled local DuckDB. Files stay on this device; no account or uploads are required. SQL reads the original opened file: save and reopen to query edits. Edited copies preserve supported schema and values but may rewrite row groups, encodings and compression. Optional usage analytics is off by default and controlled in extension Options.
