JSONL Formatter

Format JSON Lines, convert JSONL to JSON arrays, or turn arrays into JSONL.

🔒

Text stays in the browser

Formatters and encoders work on pasted text locally, which is safer for logs, snippets, and sample data.

⚡

Quick workflow

  1. Paste text or load an example.
  2. Run format, validate, encode, decode, or minify.
  3. Copy the cleaned result into your editor or workflow.
💡

Useful tip

For structured data, format first, validate next, then convert or generate schema/types if needed.
