JSON Escape

Key takeaways

• Escape raw text to a quoted JSON string
• Unescape literals back to plain text
• Client-side only
• Not a full-document formatter

What is JSON string escaping?

Escaping turns characters like quotes and newlines into JSON string escape sequences so the value is safe inside a JSON document.

Use Escape for string values you will embed in JSON. Use JSON Formatter when you need to pretty-print an entire object or array.

Features

• Escape to JSON string

  Produce a quoted JSON string ready to embed in code or payloads.

• Unescape literals

  Decode escaped sequences back into plain text.

• Flexible input

  Unescape accepts values with or without surrounding quotes.

• Copy & download

  Move results into editors, configs, or tickets in one click.

How it works

1. 1

   Paste raw text or an escaped string

   Use raw text for Escape, or a JSON string literal for Unescape.

2. 2

   Choose Escape or Unescape

   Escape produces a quoted JSON string. Unescape returns the decoded text.

3. 3

   Copy the result

   Copy or download the output for use in code or configs.

Example walkthroughs

• Multiline text

  Newlines, tabs, and quotes become escaped sequences inside a JSON string literal.

  Hello
  World	"quoted"

• Escaped literal

  Unescape restores the original multiline plain text.

  "Hello\nWorld\t\"quoted\""

Use cases

• Embed strings in JSON configs

  Safely encode messages, paths, or templates for JSON documents.

• Decode log fragments

  Turn escaped log lines back into readable text.

• Prepare test fixtures

  Generate correctly escaped string values for unit tests.

Code snippets

• Escape with JSON.stringify

  js

  Escape mode matches wrapping text as a JSON string literal.

  const literal = JSON.stringify("Hello\nWorld");
  // → ""Hello\nWorld""

Common errors

• Unescape fails on raw text

  Cause: Unescape expects an escaped JSON string (often with quotes).

  Fix: Use Escape for raw text, or paste a quoted literal for Unescape.

• Whole document became a string

  Cause: You escaped an entire JSON object as if it were plain text.

  Fix: Use JSON Formatter for documents; use Escape only for string values.

About JSON Escape

JSON Escape converts raw text into a valid JSON string literal — escaping quotes, newlines, tabs, and other characters so the value is safe inside a JSON document. Use it when you are building payloads by hand, embedding messages in configs, or cleaning strings copied from logs.

Unescape reverses the process so you can recover readable text from an escaped literal (often including surrounding quotes). This is not a full-document formatter: escaping an entire object as if it were plain text will turn the document into one big string, which is rarely what you want.

Escaping and unescaping run in your browser. Draft copy, error messages, and SQL fragments with quotes never need to leave the device. Pair with URL Encode when the next hop is a query parameter, or with Base64 Encode Text when the channel wants opaque ASCII instead of JSON escapes.

Best practice: format or validate complete JSON documents with the dedicated JSON tools; reserve Escape for string values. After unescaping, skim for leftover backslashes that indicate a double-escaped source. Prefer explicit newlines in the editor before escaping rather than pasting broken multi-line literals.
