Convert INI to JSON

Convert JSONL to JSON transforms newline-delimited data into a valid JSON array. The Convert JSONL to JSON tool runs in your browser, with live output and file support.

Paste your input above or import a file below.
No file chosen
Supported file types: .jsonl, .txt, .log
Total characters: 0

How to Use:

Start by pasting your JSONL data into the Input JSONL box. Each line should be its own complete JSON object. For example:

{ "name": "Alice", "age": 30 }
{ "name": "Bob", "age": 25 }

If your data is in a file, use the Choose File button to import .jsonl, .txt, or .log formats. As you paste or upload, Convert JSONL to JSON will instantly parse each line into a JSON object and assemble them into an array. The output shows up right away in the JSON Output box.

Click Copy Output to copy it to your clipboard or Export to File to save it as a .json file. When you’re ready to start fresh, just hit Clear All to reset everything.

What Convert JSONL to JSON can do:

This tool turns messy newline-separated JSON into structured, readable arrays. Each object on a new line becomes a proper part of the array. It gives you quick feedback, flags broken lines, and updates the output in real time. The flashing border shows when the result changes, and a live character counter helps you keep track of size. It’s fast, accurate, and always runs in your browser.

Example:

Input:

{ "name": "Alice", "age": 30 }
{ "name": "Bob", "age": 25 }

Output:

[
  {
    "name": "Alice",
    "age": 30
  },
  {
    "name": "Bob",
    "age": 25
  }
]

Common Use Cases:

Convert JSONL to JSON is perfect when you’re working with log streams, data exports, or anything that produces JSON line by line. If you use tools like Elasticsearch, BigQuery, or serverless functions that write JSONL, this tool helps you reformat the output into something usable without needing code or extra tooling.

Useful Tools & Suggestions:

Before converting, it’s worth using Fix Quotes in JSON right after the switch to clean up any key formatting issues. Then, if you’re moving between formats often, Convert JSON to YAML gives you another flexible option for structuring the same data.
