JSON Beautify/Format

Tool Introduction

The JSON Beautify/Format tool is a free online JSON processing tool designed to help users quickly and efficiently format, arrange, compress, and perform basic validation of JSON data. By adjusting indentation levels (such as 2 spaces, 4 spaces, Tab) and whether to sort key names, this tool transforms messy raw JSON data into a clear, easy-to-read, and easy-to-analyze structure, greatly improving development and debugging efficiency. It is an ideal choice for developers and data analysts.

How to Use

1. Paste the JSON text that needs to be beautified or formatted into the input box.
2. Select the output configuration according to your needs, such as indentation level (2 spaces, 4 spaces, Tab), whether to compress JSON, whether to sort JSON key names, etc.
3. Click the "Beautify" or "Format" button, and the tool will immediately process and display the result.
4. The input parameter should be a standard JSON string, supporting single-line, multi-line, and any format of JSON text.
5. The output result is a formatted or compressed JSON string, presenting different layout effects based on the selected configuration.

Usage Example

Provide real and usable examples based on configuration information, including:

• Example Input Data (raw unformatted JSON):

  {"name":"张三","age":30,"isStudent":false,"courses":["语文","数学"],"address":{"city":"北京","zip":"100000"}}

• Expected Output Result (select 2 spaces indentation, do not sort key names):

  {
    "name": "张三",
    "age": 30,
    "isStudent": false,
    "courses": [
      "语文",
      "数学"
    ],
    "address": {
      "city": "北京",
      "zip": "100000"
    }
  }

• Specific Operation Demonstration:

  1. Paste the above raw JSON data into the tool's input text box.

  2. In the configuration options, select "Indent 2 spaces" and ensure the "Sort key names" option is unchecked.

  3. Click the "Beautify" button.

  4. The output box will display the above formatted JSON data with a clear structure.

Frequently Asked Questions

• Q: What are the core functions of the JSON Beautify/Format tool?
• A: This tool mainly provides online beautification, formatting, compression, and basic syntax validation functions for JSON data. Users can customize the indentation level and choose whether to sort JSON key names, greatly improving JSON data readability.
• Q: Does this tool support processing very large JSON files?
• A: To ensure the tool's responsiveness and user experience, online tools usually have limitations on the size of input data. If your JSON file is very large, it is recommended to process it in batches or use professional desktop tools.
• Q: Is my JSON data safe? Will the tool store my data?
• A: This tool uses client-side processing technology. Your JSON data is processed only locally in your browser and will not be uploaded to the server. Therefore, your data is safe and private, and we do not store any user input data.

Notes

• Please ensure that the text you enter is a valid JSON string. If the JSON structure is incorrect, the tool may not be able to format it correctly and will prompt an error message.
• For JSON strings containing special characters (such as newlines, quotes), please ensure they are properly escaped, otherwise, it may lead to parsing errors.
• Although the tool has tried its best to optimize performance, processing very large files may still take a long time, or performance may decrease due to browser memory limitations.
• This tool only performs JSON formatting and basic syntax validation, not data content validation or semantic analysis.
