JSON String Escaper / Unescaper
Escape and unescape special characters in JSON string values. Handles double quotes, backslashes, newlines, tabs, carriage returns, and Unicode \u sequences. Real-time bidirectional conversion with a built-in escape sequence reference.
How to Use JSON String Escaper / Unescaper
How to Use the JSON String Escaper / Unescaper
Escape Mode — Raw string → JSON-safe string
Use Escape mode when you have raw text that you want to embed inside a JSON string value.
- Select the Escape tab
- Paste or type your raw string into the input
- The escaped output appears instantly on the right — ready to paste between JSON double quotes
What gets escaped
| Character | Becomes |
|---|---|
" (double quote) | \" |
\ (backslash) | \\ |
| newline (LF) | \n |
| carriage return (CR) | \r |
| tab | \t |
| backspace | \b |
| form feed | \f |
| control characters (U+0000–U+001F) | \uXXXX |
Example
Raw input:
She said "Hello"
Path: C:\Users\John
Escaped output (safe inside JSON quotes):
She said \"Hello\"\nPath: C:\\Users\\John
Unescape Mode — JSON-escaped string → raw string
Use Unescape mode when you have a JSON string value (the content between the quotes) and want to see the actual raw text.
- Select the Unescape tab
- Paste the escaped JSON string content (without the surrounding
"quotes) - The raw output appears instantly
If the input contains an invalid escape sequence, an error is displayed with a specific hint about what went wrong.
Swap
Click Swap to move the current output into the input and switch modes — useful for round-trip testing.
Unicode Sequences
Both modes handle \uXXXX Unicode escape sequences:
- Escape: control characters (U+0000–U+001F) are converted to
\uXXXXautomatically - Unescape:
\u00e9becomesé,\u0048\u0065\u006C\u006C\u006FbecomesHello
Common Use Cases
- Embedding multiline error messages or log output in JSON
- Fixing JSON parse errors caused by unescaped quotes or backslashes
- Preparing Windows file paths for JSON configuration files
- Converting database query results that contain raw strings into valid JSON values
- Debugging JSON payloads from APIs that have double-escaped strings
