Remove Duplicate Records from JSON Lines Data
Remove duplicate records from your JSON Lines / NDJSON data quickly
Remove Duplicates
Duplicate rows can cause confusion, errors, and even system failures. This tool scans your JSON Lines / NDJSON file for duplicate entries based on the fields you choose and removes the rows automatically. Whether you're cleaning up customer data, survey responses, or any other dataset, it helps ensure your file is accurate and reliable. You can choose to check for exact duplicates or compare specific columns, giving you full flexibility in how duplicates are identified.
JSON Lines / NDJSON
JSON Lines (also known as NDJSON — Newline Delimited JSON) is a text format where each line is a self-contained,
valid JSON value, typically a JSON object. It is widely used for streaming data, log files, and large data exports
because files can be read and written one record at a time without loading the entire document into memory.
Common file extensions are .jsonl and .ndjson.
