Frequently Asked Questions
JSONL (JSON Lines), also known as NDJSON (Newline Delimited JSON), is a format where each line is a valid JSON object. It's commonly used for log files, streaming data, and processing large datasets line-by-line.
When enabled, the tool converts JSONL format (multiple lines) into a single JSON array. This is useful when you need to use the data in applications that expect array format instead of line-by-line objects.
The formatter skips invalid JSON lines and displays warnings indicating which line numbers contain errors. Valid lines are processed normally, allowing you to identify and fix problematic entries.
Yes, enable the "Sort Keys" option to alphabetically sort all object keys in each line. This helps standardize data format and makes it easier to compare JSONL files.
