Frequently Asked Questions
What input does this tool expect?
A newline-delimited JSON file where each line is a valid JSON object. Empty lines are ignored.
What is the output?
A single JSON array containing all parsed objects from the JSONL input.
Is my data uploaded to a server?
No. Conversion runs entirely in your browser using JavaScript.
Example input/output
Input: {"name":"Ada"}
{"name":"Bob"}
Output: [{"name":"Ada"},{"name":"Bob"}]
How it works
This tool splits the input by newlines, parses each non-empty line as a JSON object, and wraps all results into a JSON array. Processing runs in your browser.
Common use cases
- Convert JSONL log exports into a JSON array for analysis in browser tools.
- Aggregate streaming JSONL data into a single JSON document.
- Pre-process JSONL files before importing into APIs that expect JSON arrays.
