How is this different from Excel's data cleaning?
Diwadi handles unlimited rows (Excel maxes at 1M), processes 10-100x faster, works offline with no upload, keeps data 100% private, and supports advanced operations that Excel can't handle on large files.

Is this a replacement for Alteryx?
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.
