dataformat_jsonl

Export Moodle reports as JSON Lines (.jsonl) file.

How It Works

Extends core\dataformat\base. On export:

1. Sanitizes column names (lowercase, alphanumeric).
2. Each record JSON-encoded as {col: val, col2: val2, ...} + newline.
3. Streamed directly to browser (no temp file).

JSON flags: JSON_UNESCAPED_UNICODE | JSON_THROW_ON_ERROR | JSON_UNESCAPED_SLASHES.

On JSON encode failure, outputs null for that line.

Use

Select “JSON Lines (.jsonl)” in any report export dropdown. File downloads as report.jsonl.
