Most JSON formatters break when you paste JSONL because they expect a single JSON object or array.
JSONL isn’t broken — it’s different.
This tool is built specifically for JSON Lines (ndjson). It treats each line as an independent JSON object while providing professional formatting, editing, and validation tools.
Perfect for ML engineers, data scientists, and developers who need to safely format, modify, and convert back to clean JSONL without breaking structure.

Launching **Quick JSONL Formatter** - a tool for formatting JSONLines files. **The Problem:** Standard JSON formatters break when you paste JSONL because they expect a single JSON object or array. JSONL is different - each line is an independent JSON object, making it ideal for ML training data, logs, and streaming applications.

I wanted to fine-tune GPT to write social posts in my style. JSONL formatting took me hours — endless validation errors. So I built a tool for myself. Then I made it work on my phone and published it to the web. Figured I might share it. Now it’s live. Hope it helps.
