About the JSON ↔ NDJSON Converter

The JSON ↔ NDJSON Converter is a specialized utility for developers and data engineers. It allows for quick conversion between a standard JSON array and NDJSON (Newline Delimited JSON). While standard JSON is excellent for self-contained documents, NDJSON is superior for streaming data, as each line is a valid JSON object that can be processed independently. This tool bridges the gap between the two formats, all within the security of your browser.

How to Use the Tool

  1. Select Conversion Type: Choose whether you want to convert from a standard JSON array to NDJSON, or from NDJSON to a JSON array.
  2. Input Data: Paste your data into the input text area. Use the "Load Example" button to see the expected format for each mode.
  3. Convert: Click the "Convert" button. The tool will process your data instantly.
  4. Copy the Result: The converted data will appear in the output box, ready to be copied.

Common Use Cases

  • Log Processing: Convert structured log files (often in NDJSON) into a standard JSON array for easier analysis in certain tools.
  • API Interaction: Prepare data for a bulk API that requires NDJSON by converting it from a standard JSON array.
  • Data Streaming: Convert a JSON array to NDJSON to simulate a data stream or prepare it for a streaming pipeline like Kafka or Spark.
  • Data Inspection: Quickly format an NDJSON file into a beautified standard JSON array to better inspect its overall structure.
