Question 1

What is NDJSON?

Accepted Answer

NDJSON (Newline Delimited JSON) is a format where each line is a valid JSON object. It is commonly used for log files, streaming data, and large datasets because it can be processed line-by-line without loading the entire file into memory.

Question 2

How is NDJSON different from JSON?

Accepted Answer

Standard JSON is a single data structure (object or array), while NDJSON is a sequence of JSON values separated by newlines. NDJSON is ideal for streaming and append-only logs, while JSON is better for structured documents. Diakrio can convert between both formats.

Question 3

Can I convert large NDJSON files?

Accepted Answer

Diakrio parses NDJSON line-by-line. Supported browsers save the JSON array directly to disk; other browsers use a bounded in-memory fallback. Practical limits still depend on line size, transforms, runtime overhead, and disk space.

Question 4

What happens if an NDJSON line is invalid?

Accepted Answer

Diakrio validates each line as it is parsed. Invalid JSON lines are reported with details (line number and error message), and you can choose to skip invalid lines or halt conversion. This helps identify malformed log entries.

Question 5

When should I use NDJSON instead of JSON?

Accepted Answer

Use NDJSON for streaming data, log files, and large datasets that need append-only writes. Use standard JSON for configuration files, API responses, and when you need a single hierarchical structure. Diakrio supports both directions.
