Is my data private? Does anything get uploaded?

Your data never leaves your device. All cleaning logic runs in your browser using DuckDB WebAssembly — a local SQL engine. No rows, column names, or file contents are transmitted to Refinata's servers or any third party. The AI Smart Suggestions also run locally by analyzing statistical patterns in the data, not by sending data to an AI API. The only network request is downloading the DuckDB WASM binary on first use (approximately 5MB, cached in your browser).

How does the CSV cleaner compare to Excel's built-in tools?

Excel requires manual steps for most of these operations: Remove Duplicates is one click but only removes exact duplicates. Trimming whitespace requires the TRIM() formula applied cell-by-cell. Standardizing null values requires Find & Replace with 6–10 separate runs for each variant (N/A, NULL, none, etc.). Date standardization requires Text-to-Columns or Power Query. Refinata applies all of these simultaneously in a single click, on files of any size, with a detailed change report, and without any server upload.
