About this conversion
This tool converts Parquet files to XML format directly in your browser — no account required, no file upload, no waiting for a server. It processes your data entirely within your browser using WebAssembly, so nothing ever leaves your device.
The tool preserves all columns and data types from your source file and writes a valid XML file ready to download. Large files are handled efficiently using a vectorised columnar engine.
