About this tool

Recover the original text from an escaped Java string. Emits `\uXXXX` for every non-ASCII character, which keeps source files portable across encodings.

When you would use it

  • Reading an escaped Java value from a log or config
  • Recovering text pasted from source code
  • Decoding a value before processing it

Worked example

Escaped Java
He said \"hi\"\nC:\\temp
Text
He said "hi"
C:\temp

Things worth knowing

  • Escaping and unescaping are exact inverses: running one then the other returns your original text byte for byte.
  • Unescaping is done in a single pass, so a literal backslash followed by n is not mistaken for a newline — a bug that affects many escaping tools.
  • Non-ASCII characters become \uXXXX, keeping source files safe regardless of file encoding.
Questions

Frequently asked

Does this round-trip exactly?
Yes. Escaping then unescaping returns your input unchanged, including backslashes, newlines and emoji. That property is covered by the test suite.
Which characters get escaped?
Emits \uXXXX for every non-ASCII character, which keeps source files portable across encodings.
Is my data uploaded anywhere?
No. Every tool on JSONWorks runs entirely in your browser using JavaScript. Your input is never sent to a server, never logged and never stored. The simplest proof is to disconnect from the internet — the tools keep working. The site does load Google Fonts and a Google Analytics page-view tag, so you will see those two requests in your network tab, but neither receives anything you type or paste.
