About this tool
Make arbitrary text safe to place inside a Java string. Emits `\uXXXX` for every non-ASCII character, which keeps source files portable across encodings.
When you would use it
- Embedding text in Java source safely
- Preparing a fixture or test value
- Neutralising characters that would break the surrounding syntax
Worked example
He said "hi" C:\temp
He said \"hi\"\nC:\\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
nis 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?

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.
