How to Use JSON String Escaper — Quote & Unicode Tool

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.

  1. Select the Escape tab
  2. Paste or type your raw string into the input
  3. The escaped output appears instantly on the right — ready to paste between JSON double quotes

What gets escaped

CharacterBecomes
" (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.

  1. Select the Unescape tab
  2. Paste the escaped JSON string content (without the surrounding " quotes)
  3. 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 \uXXXX automatically
  • Unescape: \u00e9 becomes é, \u0048\u0065\u006C\u006C\u006F becomes Hello

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
