How this service works
Remove duplicate rows from CSV text by all columns or a subset of key columns; returns cleaned CSV plus a report of how many rows were removed.
Output
Returns a cleaned CSV with duplicate rows removed, along with a report indicating how many rows were deduplicated (total input rows, output rows, and removed count).
Example use cases
Email list deduplication before campaign
“I have a CSV of email subscribers and there are definitely duplicates — can you deduplicate it using the 'email' column as the key and tell me how many rows got removed?”
Full-row deduplication of exported report
“Here's a CSV export from our database — please remove any completely identical rows across all columns and give me the cleaned version back.”
CRM contact deduplication by ID
“I've got a CRM export in CSV format with duplicate contact records — deduplicate it by the 'contact_id' column and show me a summary of what was removed.”
Technical details
Endpoint
POSThttps://api.24klabs.ai/api/v1/csv-dedupeWhen to prefer
Use this endpoint when you need a quick, programmatic way to deduplicate CSV data without spinning up a full data pipeline or loading data into a database. Ideal for lightweight ETL tasks, data cleaning before imports, and when you want both a cleaned output and a count of removed rows in one call.
Side effects
- Malformed CSV input returns a parse error
- Invalid or non-existent column name specified as key returns an error
- Empty CSV input may return an empty result or error
- Very large CSV payloads may time out or hit size limits
- Non-UTF-8 encoded CSV may cause parsing failures
