JSON Escape & Unescape Features
Professional tools for escaping and unescaping JSON strings, perfect for developers working with APIs, databases, and code generation.
JSON String Escaping
Escape special characters like quotes, newlines, and backslashes to embed JSON in code strings. Supports multiple escape levels for nested string embedding.
URL Encoding/Decoding
Convert JSON to URL-safe format with percent encoding for query parameters and API requests. Decode URL-encoded strings back to readable text.
HTML Entity Encoding
Escape HTML special characters to safely display JSON in HTML without breaking markup. Convert <, >, &, and quotes to entity codes.
Unicode Escape Sequences
Convert non-ASCII characters to \uXXXX Unicode escape sequences for maximum compatibility across systems and character encodings.
How to Escape & Unescape JSON
Transform JSON strings in three simple steps for embedding in code or restoring readability.
Choose Operation Mode
Select whether you want to escape (add backslashes) or unescape (remove backslashes) your text. Choose the escape type: JSON string, URL encoding, HTML entities, or Unicode.
Paste or Upload Text
Enter your JSON or text directly in the editor, or upload a file. The tool auto-detects escaped text and suggests the appropriate operation mode.
Process & Copy Result
Click Escape or Unescape to transform your text instantly. Copy the result to clipboard, download as a file, or use it as input for another operation.
Frequently Asked Questions
What is JSON escaping?
JSON escaping adds backslashes before special characters (like quotes, newlines, tabs) so JSON can be safely embedded inside strings. For example, a newline becomes \n and a quote becomes \". This is essential when embedding JSON in code or storing it as a string value.
When should I escape JSON?
Escape JSON when embedding it in JavaScript/TypeScript strings, storing JSON in database string fields, sending JSON in API requests as string payloads, or generating code that includes JSON literals. Escaping prevents syntax errors and security issues.
What are escape levels (1x, 2x, 3x)?
Escape levels control how many times characters are escaped. Single (1x) escapes once (\"), double (2x) escapes twice (\\"), and triple (3x) escapes three times (\\\"). Use higher levels when embedding strings within strings, like JSON inside a JSON string.
What's the difference between JSON and URL escaping?
JSON escaping uses backslashes (\n, \") for embedding in code strings. URL escaping uses percent encoding (%20, %22) for safely including text in URLs and query parameters. Each serves different purposes—use JSON escaping for code, URL escaping for web requests.
Is my data safe when using this tool?
Yes, 100% safe. All escaping and unescaping happens entirely in your browser—your data never leaves your device or gets sent to any server. The tool works offline after loading, ensuring complete privacy and security for sensitive data.
Can I unescape already escaped JSON?
Absolutely! The unescape mode converts escaped strings back to readable format. The tool automatically detects escaped text when you upload files and suggests switching to unescape mode. You can toggle between escape and unescape modes anytime.
