Yes! Diwadi handles CSV files with billions of rows. Clean 10M, 50M, or 100M+ row files that Excel can't even open. Perfect for database exports, log files, and enterprise datasets.

For most users, yes! Diwadi provides the same core data cleaning features as Alteryx (remove duplicates, filter, clean, convert) but is free and simpler to use. Alteryx costs $5,195-50,000/year and is complex for simple tasks.

Clean CSV, Excel (XLSX/XLS), Parquet, TSV, and JSON files. You can also convert between formats during the cleaning process. For best performance with large files, use Parquet.

Completely free with unlimited files and rows. No file size limits, no watermarks, no credit card required.
