Question 1

What is the benefit of CSV to NDJSON conversion?

Accepted Answer

NDJSON is optimized for streaming and line-by-line processing. Converting CSV to NDJSON makes it easier to work with log aggregation systems, data pipelines (like Kafka or Fluentd), and command-line tools. Each CSV row becomes a standalone JSON object on its own line.

Question 2

How does the CSV to NDJSON converter work?

Accepted Answer

Diakrio parses your CSV file row-by-row, automatically detecting the delimiter and headers. Each row is converted into a JSON object with field names from the CSV header. These objects are written as NDJSON, one per line, making it ideal for streaming scenarios.

Question 3

Can I convert large CSV files to NDJSON?

Accepted Answer

Diakrio parses rows incrementally and can persist output chunks directly to disk in supported browsers. Capacity depends on record size, transforms, browser overhead, and disk space. Live telemetry reports MB/s, records/s, and observed resource use.

Question 4

What CSV delimiters are supported?

Accepted Answer

Diakrio auto-detects common delimiters: comma, semicolon, tab, and pipe. You can also manually specify custom delimiters. The parser handles quoted fields, escaped characters, and different line endings automatically.

Question 5

Is NDJSON better than JSON for CSV data?

Accepted Answer

It depends on your use case. NDJSON is better for streaming, log processing, and append-only scenarios because each line is independent. Standard JSON arrays are better for hierarchical data and when you need to load the entire dataset into memory at once. Diakrio supports both.
