Convert CSV to NDJSON JSON Lines
Convert every CSV row into newline-delimited JSON for APIs, logs, BigQuery, and data pipelines.
NDJSON, also called JSON Lines or JSONL, stores one valid JSON object per line. That makes it convenient for streaming imports, logs, API fixtures, and tools that process records incrementally.
Use CSV to NDJSON to turn each CSV row into one JSON object. The header becomes the object keys and each record stays on its own line.
Use NDJSON to CSV when you need to bring the records back into a spreadsheet. Nested objects are represented using dotted column names so the output remains tabular.
