JSON to JSON Lines Converter: Convert Arrays Online
Convert a JSON array to JSON Lines (NDJSON), with each compact JSON object on its own line. Use the reverse toggle to join JSON Lines back into a JSON array. JSON Lines is commonly used for streaming and log processing, so this converter helps you prepare data for tools and workflows that use that format.
The JSON to JSON Lines converter turns a JSON array into JSON Lines, also known as NDJSON. It gives developers a straightforward way to prepare JSON data for workflows that expect one compact JSON object per line, then copy the converted result where it is needed.
For JSON to JSON Lines conversion, paste a JSON array and the tool outputs each object on its own line. To go the other way, use the reverse toggle to join JSON Lines back into a JSON array. The input identifies the available direction control as a reverse toggle; no other conversion options are specified here.
JSON represents structured data, including arrays that can contain multiple objects. JSON Lines places separate JSON records on individual lines, a format used for streaming and log processing. Converting between them can help when data needs to move between a JSON-based workflow and a tool or process that uses JSON Lines. The converter's JSON Lines output uses compact JSON objects, one per line.
The conversion runs entirely in your browser: your input is processed on your device and is not sent to a server. The tool is free, and after the page has loaded, it works offline without a server connection. It can help developers and DevOps engineers prepare, review, and move JSON data between formats without uploading it.
Step 1: Paste your JSON input into the tool. For JSON to JSON Lines conversion, provide a JSON array.
Step 2: Choose the conversion direction with the reverse toggle. Convert an array to JSON Lines, or join JSON Lines back into an array.
Step 3: Review the generated result. JSON Lines output places one compact JSON object on each line.
Step 4: Copy the result and use it in your code, documentation, or the next tool in your workflow.
Use case: Move JSON array data into a system that accepts JSON Lines. The converter puts each object on a separate line.
Use case: Convert data for streaming or log-processing workflows that use JSON Lines.
Use case: Check whether JSON Lines you received corresponds to the JSON array you expected by converting it back into an array.
Use case: Prepare JSON snippets for documentation, a ticket, or a commit message in the format your team needs.
Use case: Sanity-check a conversion before pasting the result into code.
Use case: Switch between JSON arrays and JSON Lines when moving data between tools that use different formats.
Use case: Create a line-by-line JSON representation of an array of objects for a workflow that expects one object per line.
