How to Convert Text to Unicode Escapes

A practical workflow for escaping text safely for JSON, source code, and API payload debugging.

Step 1

Add Your Input Text

Paste or type text into the editor. You can upload text files, try sample input, and clear instantly. This is useful before sending payloads through JSON pipelines and browser-side TextEncoder workflows, and before placing strings into JSON escape workflows or encoded payloads.

Input Tips

  • Paste raw text directly from logs, APIs, or editors.
  • Use upload for .txt/.json/.yaml files when handling longer content.
  • Use sample input first if you want to verify behavior quickly.
  • Keep line breaks if you need exact escaped output for test fixtures.

Example Input

Hello, World! name: Cafe Munchen currency: EUR status: active
Step 2

Get Unicode Escaped Output

The output updates in real time as \\uXXXX sequences. Characters beyond BMP are represented as surrogate pairs so they remain compatible with ECMAScript and Unicode standard parser behavior.

What Gets Escaped

Letter A
A -> \u0041
Space
[space] -> \u0020
Newline
\n -> \u000A
Supplementary Character
U+1D11E -> 𝄞

Example Output

\u0048\u0065\u006C\u006C\u006F\u002C\u0020\u0057\u006F\u0072\u006C\u0064\u0021\u000A \u006E\u0061\u006D\u0065\u003A\u0020\u0043\u0061\u0066\u0065\u0020\u004D\u0075\u006E\u0063\u0068\u0065\u006E
Step 3

Copy or Download

Copy escaped output for source code and API requests, or download as a text file. To reverse the conversion, use the Unicode Unescape tool.

Output Workflow

  • Copy escaped text into JavaScript, TypeScript, Java, or JSON values.
  • Download output when sharing payload fixtures with a team.
  • Keep one escaped version and one raw version for easier debugging.
  • Use consistent escaping across test environments to avoid mismatch bugs.
Step 4

Validate with Round-Trip Testing

For reliability, verify your escaped text by converting it back and comparing it with the original. This catches hidden whitespace, newline, and character encoding issues early.

Recommended Validation Sequence

1. Escape original input on this page.
2. Paste output into Unicode Unescape and decode.
3. Compare decoded value with your source text.
4. If needed, use Compare Text to detect exact differences.

Frequently Asked Questions

What is Unicode escaping?

Unicode escaping converts characters into code point notation like \\u0041. This makes text safe for many code and serialization contexts defined by Unicode rules.

Why do I need this for JSON and APIs?

Escaped strings reduce issues with special characters and encoding mismatches across systems. It is especially useful for logs, payload transport, and source-controlled test fixtures in JSON APIs.

Is Unicode escaping the same as URL encoding?

No. Unicode escaping uses \\uXXXX notation for code and data serialization contexts. URL encoding uses percent encoding like %20 for URL-safe transport defined in RFC 3986.

Does this support supplementary and non-Latin characters?

Yes. Non-BMP characters are emitted as surrogate pairs (for example, U+1D11E becomes \�\�) for broad compatibility with the latest Unicode versions.

Is this tool client-side?

Yes. Conversion runs in your browser only. Your input is not sent to a backend service.
