Free, privacy-first XML to Parquet converter. Flatten XML data and compress into Parquet format directly in your browser. No uploads, no servers.
Nested elements and attributes are automatically flattened into columns using dot notation. No manual mapping or XSLT required.
Parquet stores data by column rather than by row, enabling high compression ratios. Expect 5-10x smaller files compared to raw XML.

Filter rows, rename columns, change types, aggregate data, or remove duplicates before writing the Parquet file.
No sign-up, no trial, no watermarks. Convert as many XML files to Parquet as you need, completely free.
