JSON Escape & Unescape Tool Online
Escape or unescape special characters in JSON strings instantly. Our free JSON Escape Unescape Tool ensures your strings are safe for storage, APIs, and code embedding.
About JSON Escape & Unescape Tool
Special characters in strings can break JSON syntax if not properly escaped. This tool escapes newlines, quotes, tabs, and other special characters for safe JSON embedding, or unescapes them back to readable text.
How it works
Select Escape or Unescape mode using the tabs. Enter your text and click the process button. Escaping converts special characters to their backslash sequences, while unescaping reverses the process.
The info card at the bottom shows which characters will be processed. Use the Swap button to quickly toggle between modes and test round-trip conversion.
When you'd use this
You need to include user-generated text with special characters inside a JSON string value. Escape it here first to ensure the JSON remains valid and parseable.
This handles common escape sequences but doesn't validate full JSON syntax. For complete JSON validation, use a dedicated JSON validator tool alongside this one.
Questions
Which characters are escaped?
Backslash, double quotes, newlines, tabs, carriage returns, form feeds, and backspaces are all escaped with backslash sequences.
When should I escape JSON strings?
Escape strings before embedding them in JSON, JavaScript code, or configuration files where special characters could cause syntax errors.
Can I unescape any escaped string?
Yes, strings escaped by this tool can be unescaped back to the original. Invalid escape sequences may cause errors during unescaping.
What about Unicode characters?
This tool handles basic escape sequences. Unicode characters are preserved as-is unless they require escaping for JSON compatibility.
