Mastering the JSON Formatter

JSON (JavaScript Object Notation) is everywhere in modern development. Here's how to work with it efficiently using UtilOS.

Basic Formatting

Paste your JSON and click format. It's that simple! But there's so much more you can do.

Validation

Our formatter doesn't just prettify - it validates. Common errors we catch:

• Missing quotes around keys
• Trailing commas
• Mismatched brackets
• Invalid escape sequences

{
  "name": "John",
  "age": 30,
  "city": "New York"
}

Minification

Need compact JSON for production? Use the minify option to remove all whitespace:

{"name":"John","age":30,"city":"New York"}

Working with Large Files

For files over 1MB:

1. Use the file upload option instead of paste
2. Enable streaming mode for better performance
3. Consider splitting into smaller chunks
