JSON escaping refers to encoding special characters in a string by adding a backslash () to ensure the proper parsing of JSON data.
JSON unescaping is the process of restoring escaped characters back to their original form, commonly used in scenarios such as data display or cross-system transmission.

" |
\" |
Double quote (string boundary) |
\ |
\\ |
Backslash (escape identifier) |
/ |
\/ |
Slash (used in XSS attack prevention scenarios) |
\b |
\\b |
Backspace |
\f |
\\f |

\n |

}Prevent Data Pollution
Automatically identifies 32 types of syntax issues, such as unclosed quotes and incorrect escape sequences.
Multi-Encoding Compatibility
Supports processing Unicode characters (e.g., \u4e2d\u6587 ↔ "中文").
Intelligent Context Handling
Retains comment content (// Configuration item) without escaping it.
Skips reprocessing already escaped characters.
Enterprise-Level Security
All data processing is completed locally in the browser and supports offline mode.
Q: Will the size of the JSON file increase after escaping?
A: Each escape character adds 1 byte. It is recommended to enable "Compressed Escaping" mode for large data (removing extra spaces).
Q: Do HTML special characters (<>&) need to be escaped?
A: The JSON standard does not require it, but it is recommended to escape them in the \u003c format to prevent XSS attacks.
Q: What should I do if escaping errors cause data corruption?
A: Use the "Version Comparison" feature to restore the last 5 operation records.
