Escape JSON
This free JSON Escape Tool helps you clean up your JSON strings by escaping them so they're safe, readable, and won't break anything when used in code.
Escaping or unescaping a JSON string basically means converting special characters into a format that won't cause errors. For example, a line break or a quote inside your string might confuse the parser—this tool fixes that instantly.
What Does It Actually Do?
In simple terms, it transforms your input JSON string by replacing characters that could mess things up during parsing. These are known as "reserved characters" in JSON and must be escaped properly if you want your JSON to be valid and work across different systems.
Here's how it transforms special characters:
- Backspace →
\\b - Form feed →
\\f - Newline →
\\n - Carriage return →
\\r - Tab →
\\t - Double quote →
\\" - Backslash →
\\\\
Copy and paste your raw JSON into the tool, and choose to either escape or unescape it. That's it—your data gets instantly cleaned up for safe use.
Need to Handle Emojis or Non-English Characters?
When you enable the Unicode escape option, the tool will also convert emojis 😊 and special characters like ©, ñ, and ✓ into their Unicode format like \\uXXXX. This is useful when working in environments that don't handle UTF-8 very well.
Input:
{"message": "Hello 😊"}Output (escaped):
{"message": "Hello \\uD83D\\uDE0A"} How to Use It
- Paste your JSON into the input box.
- Choose escape or unescape mode depending on what you need.
- Click the button—your cleaned-up JSON appears instantly, ready to copy.
Why Should You Care About Escaping?
If you try to paste unescaped JSON into JavaScript, HTML, or a log file, it might throw errors or behave weirdly. Things like quotes, newlines, or emojis can break your syntax if not escaped properly. Escaping solves that. Unescaping, on the other hand, makes your JSON easier to read when you're reviewing raw or encoded data.
Best Practices for Clean JSON
- Always escape before embedding JSON into code or markup.
- Use unescape mode for readability during debugging or manual edits.
- Turn on Unicode escaping when working with non-ASCII characters.
- Validate your final JSON with a linter or parser.
Whether you're a developer, analyst, or just trying to make sense of a messy JSON string—this tool is your quick fix for clean, error-free data.
