JSON Escape

When you embed JSON in another string, a log template, or a code literal, quotes and newlines need to be escaped first.

Escape handles common control characters. Unescape turns \n and \" back into real characters so you can format again.

Good for debugging a wrapped response or pulling nested JSON out of a config. Don't use it to change business meaning.

Everything stays local. Strings that contain tokens can be pasted as-is.

Peel one layer at a time

Some logs escape JSON twice. Unescape once, see if it is still a literal, unescape again if needed, then send it to Format.

How this differs from the Unicode page

Escape handles quotes, backslashes, and newlines. Turning CJK into \uXXXX belongs on the Unicode tool. Don't mix the buttons.

How to use it

  1. Paste JSON or plain text.
  2. Click Escape to embed in a string; click Unescape to restore a literal.
  3. If unescape yields valid JSON, expand it on the Format page.
  4. Copy the result. Use the Unicode page for \u encoding.
  5. On multi-layer escapes, look at each result before the next step.

When to use it

  • Put JSON inside a Java or C# string literal.
  • Restore real JSON from an escaped log field.
  • Prepare single-line text for CSV or a message queue.
  • After Clean removes junk, peel leftover escapes.

Keep in mind

  • Ordinary CJK stays as-is by default.
  • Unescape usually fails because a backslash layer is missing, or the text was never a valid escape.
  • Don't escape JSON that is already an object and expect to parse it directly.

FAQ

Does it change Chinese characters?

Ordinary CJK stays as-is. Use the Unicode tool when you need \uXXXX.

What if unescape fails?

You may be missing a backslash layer, or the text is not a valid escape sequence. Check the original.

How do I use this with Format?

Unescape until you have valid JSON, then format or validate.

Is it uploaded?

No.

Do newlines become \n?

Yes when you escape. Unescape turns them back into real newlines.

Does it handle HTML entities?

It does not decode " and similar entities. Decode those elsewhere first.

How is this different from Minify?

Minify strips whitespace but stays JSON. Escape turns text into something you can embed in a string.

Will it touch backslash paths?

Backslashes in Windows paths are treated as escapes. Confirm whether you want a path or JSON before you run it.
