Cómo usar Formateador JSON

Paste or type your raw JSON into the input panel on the left. Click **Format** to instantly beautify it with proper indentation, or click **Minify** to compress it into a single line. You can choose between 2-space and 4-space indentation using the dropdown. The tool also validates your JSON in real time - if there's a syntax error, you'll see a clear error message pinpointing the issue. Click **Sample** to load example JSON and see the formatter in action. Everything runs locally in your browser - your data never leaves your device.

1

Paste your JSON

Click inside the left editor panel and paste your raw, unformatted JSON data.

2

If the data is invalid, the bottom banner will turn red and identify the syntax error. Fix it before proceeding.

3

Format or Minify

Click the 'Format JSON' button to beautify the code with proper indentation, or click 'Minify JSON' to compress it.

4

Copy or Download

Click the Copy button to copy the formatted result, or use Download to save it as a .json file.

Preguntas frecuentes

Is this JSON formatter free to use?+
Yes, completely free with no sign-up required. Use it as many times as you need.
Does my JSON data get sent to a server?+
No. All formatting and validation happens 100% in your browser. Your data never leaves your device.
What is the difference between formatting and minifying JSON?+
Formatting (beautifying) adds indentation and line breaks to make JSON human-readable. Minifying removes all unnecessary whitespace to reduce file size - useful for production APIs and config files.
Can this tool fix broken JSON?+
The tool will identify and highlight syntax errors like missing commas, unclosed brackets, or invalid characters, but it won't auto-fix them. You'll need to correct the errors manually based on the error messages.
