What is Reparatio?
Reparatio is a file format conversion service that handles the formats data professionals actually encounter: CSV, Parquet, Arrow, Avro, ORC, Feather, JSONL, Excel, GeoJSON, and more. Upload a file in one format, download it in another — no Python environment required, no command-line fumbling, no install. The first 50 rows of every conversion are free so you can verify the output is correct before paying.
Who it’s for
You have a file in the wrong format and need it in the right one. You have probably already tried opening it in Excel and failed. Reparatio fixes it in seconds, in the browser.
REST API, MCP server, Python SDK, and CLI tool. Integrate format conversion into your pipeline without writing the conversion logic yourself or managing Polars and Pandas dependencies.
Parquet, Arrow, Feather, and ORC are first-class citizens. Stop writing conversion cells in your notebooks. Reparatio understands your formats.
