About JSON to NDJSON Conversion
JSON and NDJSON they are both data formats but work different. JSON is like a box that holds all data together. NDJSON is like taking each item from that box and putting each on its own line. That's JSONL or Newline Delimited JSON.
How to Use This Tool
- Take your JSON data from anywhere - API, file, database
- Paste it into the big box above
- Click the convert button that says "Convert to NDJSON"
- Get your NDJSON output in the bottom box
- Copy it and use it wherever you need
- That's all. Simple.
Benefits of NDJSON Format
NDJSON is better for some things. Big data processing it's easier with NDJSON. Because each line is separate JSON object. You can read line by line without loading everything in memory. Streaming data is perfect for NDJSON. Log files also good as NDJSON. Machine learning data often in NDJSON format.
JSON is good for configuration files. NDJSON is good for data pipelines. Both have their place but you need to know which one to use when.
Performance Difference
Performance wise NDJSON usually faster for large datasets. Because you can process streamingly. JSON you have to parse whole thing at once. Memory usage NDJSON is better because you handle one line at a time. For small data doesn't matter much. For gigabytes of data NDJSON wins.
Think of it like this: JSON is like a big bucket of water. You have to carry whole bucket. NDJSON is like water pipes. Water flows through pipes continuously. That's the main difference in performance thinking.
Privacy and Security
Important: Your data stays on your computer. We don't send it anywhere. The conversion happens right here in your browser using JavaScript. No server storage. No logging. Nothing saved. When you close the page, your data is gone.
This is crucial for sensitive data. We understand developers work with private information. API keys, user data, business data - all safe. We don't want your data. We just provide the tool.
Common Questions
What if my JSON is invalid?
Our tool tries to fix common errors. Unquoted keys, trailing commas, single quotes instead of double quotes - we try to fix these. But perfect JSON is always best.
What's the difference between NDJSON and JSONL?
Same thing. Different names. NDJSON means Newline Delimited JSON. JSONL means JSON Lines. Both mean each line is separate JSON object.
Does it work with nested JSON?
Yes. Nested objects, arrays, complex structures - all work. Each top-level array element becomes separate line in NDJSON.
Can I convert huge files?
Browser has memory limits. For huge files better use command line tools. But for most normal use cases up to 50MB it works fine.
Why use this instead of other tools?
Many tools break with malformed JSON. Our tool tries to fix errors. Also we don't send your data to server. Many online tools send your data somewhere. We don't. That's important difference.
What about special characters?
Unicode characters, emojis, special symbols - all preserved correctly. UTF-8 fully supported.
