Formatting JSON Made Easy
Published: May 2025
JSON (JavaScript Object Notation) is a lightweight data-interchange format that's easy for humans to read and write, and easy for machines to parse and generate. But when JSON is minified or improperly formatted, it can be nearly impossible to understand at a glance.
Why Format JSON?
- To make API responses readable
- To identify and fix syntax errors
- To compare data structures easily
- To validate before use in development
How to Use a JSON Formatter
You can easily format JSON using the JSON Formatter Tool on 72zq.com. Simply paste your raw JSON into the input area and click “Format.” The beautified output will appear below, properly indented and structured.
Common JSON Issues
- Missing commas between key-value pairs
- Unquoted keys or values
- Extra or missing braces/brackets
- Incorrect nesting or data types
Tips for Working with JSON
- Always validate your JSON before using it in production
- Use consistent indentation (2 or 4 spaces)
- Wrap keys and string values in double quotes
