JSON Stringify Tool
Convert text to a JSON string by escaping special characters, or parse a JSON string back to readable text.
What is JSON Stringify?
JSON.stringify() is a JavaScript function that converts a value into a JSON string. When applied to text, it escapes special characters so the string is valid inside a JSON document or JavaScript source code. For example, a newline character becomes \n, a tab becomes \t, and double quotes become \".
How to Use
- In Stringify mode: paste text to convert it to a valid JSON string
- In Parse mode: paste a JSON string to unescape it back to plain text
- Toggle options like unicode escaping and surrounding quotes
- Copy the result for use in your code
Frequently Asked Questions
Which characters are escaped?
The JSON spec requires escaping: \ (backslash), " (double quote), and control characters (\n \r \t \b \f and any char below U+0020).
When should I escape non-ASCII characters?
Usually you don't need to — JSON natively supports Unicode. But some systems or protocols require all characters to be ASCII-safe, in which case non-ASCII chars should be \uXXXX escaped.
What is the Parse mode for?
Parse reverses the process: given a JSON string (with escape sequences), it produces the original text. Useful for reading escaped strings in API responses or JSON files.
Can I stringify multi-line text?
Yes. Multi-line text is automatically stringified with \n (or \r\n) escape sequences — it becomes a single-line JSON string.
Is this the same as JSON.stringify in JavaScript?
Yes, for strings. The tool replicates the same escaping rules. Note: JSON.stringify on objects also serializes data structures, which this text-focused tool does not do.
