🧽 Dataset Deduplicator - Clean Any Scraped Dataset

that_red_bird/dataset-deduplicator

🧽 Upload any dataset — scraped rows, a RAG corpus, an export — and get back exact AND near-duplicates removed, plus a per-field data quality report. ✅ MinHash + LSH banding finds near-duplicate text at scale without O(n²) pairwise comparison.

Remove duplicate rows from an Apify Dataset or inline JSON. Deduplicate by selected fields, trim strings, and write the cleaned rows to a new Dataset.

Unique handle keys from a public JSON catalog. Try is ColourPop — distinct from v1 Allbirds. $0.002 / unique row.
