JSON List ↔ Lines Converter Online — Convert JSON Arrays to Text Lines

Need to convert a JSON array into simple text lines, or turn a list of lines into a JSON array? This free tool handles both directions instantly. Supports formatted and inline output, configurable indentation, and empty line skipping.

Comment Utiliser Cet Outil

  1. Choose direction — Select "JSON → Lines" to extract values from a JSON array, or "Lines → JSON" to create a JSON array from text lines.
  2. Paste your input — Paste a JSON array like ["a","b","c"] or paste newline-separated lines into the input panel.
  3. Configure output — For Lines → JSON, toggle formatted output and choose indentation (2 or 4 spaces).
  4. Copy the result — The converted output appears instantly. Click Copy to use it.
  5. Chain with other tools — With Auto-fill enabled, your output automatically carries over when you open another tool from the sidebar. Use the back and forward arrows to undo navigation and restore your previous tool state including all options.

Questions Fréquemment Posées

What is a JSON array?
A JSON array is an ordered list of values enclosed in square brackets, like ["apple", "banana", "cherry"]. Each value can be a string, number, object, or other JSON type.
Can I convert a JSON array of objects?
When converting JSON to lines, objects are serialized to their JSON string representation. Each object becomes one line.
What happens if my JSON is invalid?
The tool shows an error message and the status bar indicates "Valid JSON: No". Fix the syntax error and the output updates automatically.
What indentation options are available?
You can choose between 2-space and 4-space indentation when formatted output is enabled.
Does it handle nested arrays?
Nested arrays are serialized as JSON strings when converting to lines. Only the top-level array elements become individual lines.
Is my data stored anywhere?
No. All processing happens in your browser. Your data is never sent to any server.
