DATA-CLEANING API
Deduplicate CSV rows and keep evidence of exactly what changed.
Send CSV text plus the columns that define a duplicate. Receive cleaned CSV, input and output row counts, removed-row count, detected delimiter, and SHA-256 hashes for reproducible provenance.
DETERMINISTIC OUTPUT
Small enough for an automated workflow, explicit enough to audit.
Evidence returned
- Clean CSV in the response
- Input, output, and removed row counts
- Detected comma, semicolon, tab, or pipe delimiter
- SHA-256 hashes of input and cleaned output
