Frustrated by a popular profiling library taking 42 seconds on just 891 rows, three developers built ZEDDA to handle dataset profiling, data quality analysis, cleaning suggestions, validation, ML readiness checks, and AI-powered Q&A — all with a simple Python API backed by C++ for performance. The project supports CSV, Parquet, and Pandas DataFrames and is available via pip. ## Full article daily.dev links to this article rather than hosting it.
