About this tool
Recover the original text from an escaped CSV string. Wraps a field in quotes only when it contains a delimiter, quote or newline, doubling any interior quotes.

- Reading an escaped CSV value from a log or config
- Recovering text pasted from source code
- Decoding a value before processing it
Worked example
He said \"hi\"\nC:\\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. - Emoji and other astral-plane characters are handled as surrogate pairs, so they survive the round trip intact.
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?
Wraps a field in quotes only when it contains a delimiter, quote or newline, doubling any interior quotes.
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.
