Question 1

What are .jsonl or .ndjson files?

Accepted Answer

JSON Lines (`.jsonl`) or Newline Delimited JSON (`.ndjson`) is a text format for storing structured data where each line is a separate, valid JSON object. This format is useful for streaming data or processing large datasets one record at a time.

Question 2

How do I use this viewer?

Accepted Answer

Click the "Open Local File" button to select a `.jsonl` or `.ndjson` file from your device. Its content, a sequence of JSON objects each on a new line, will be displayed as plain text.

Question 3

Does this tool validate each JSON line?

Accepted Answer

No, this viewer displays the raw text content. It does not parse or validate each individual JSON object within the file. For detailed validation, you might use a JSON linter or a script.
