JSON Unescape Online for Free
A JSON unescape tool reads a backslash-escaped string and writes back the original JSON document.
Backend developers use it when a log line shows the API response as one long stringified blob with every quote turned into a backslash-quote. QA engineers need it when a fixture stored as a column value in a database has been double-serialized on the way in.
How to Unescape a JSON String with Our Tool
- Drop the escaped string in: paste it into the editor on the left, drag a .json, .txt, or .log file onto the input area, or click Upload File.
- Pick the mode that matches the input: JSON Unescape for a single-layer escape, Deep Unescape when the log line has been wrapped two or three times, String Unwrap to see each step in order, or Batch Unescape when a dozen rows from a database need the same pass.
- Read the output as JSON: the right pane prettifies the result the moment the string parses, and the status bar names the layer count so a triple-wrap is no longer a guess.
- Take the result out: Copy puts the clean JSON on your clipboard, Download saves it as a .json file ready to paste into the bug ticket.
Features of Our JSON Unescape Tool
Outer Quote Stripper
The outer quote stripper drops the wrapping quotes on a stringified payload before the unescape pass so a copy from a log file works without an editor cleanup step.
Unicode Escape Resolver
The Unicode escape resolver turns \\u00e9 back into é so a French customer name in a log line reads as the original character instead of a code point.
Deep Unescape Pass
The deep unescape pass keeps unwrapping up to ten layers so a payload that was serialized through a queue, a logger, and a webhook still comes out as the original object.
Layer-Counted Status Bar
The layer-counted status bar prints "3 layers" next to the result so a debugging session sees the exact depth of escaping instead of guessing.
Step-by-Step Unwrap View
The step-by-step unwrap view renders each intermediate string as a numbered card so a review can point at the exact pass where a double-encode crept in.
Batch Line Mode
Batch line mode unescapes one entry per line so a dump of a hundred database rows reads back as a hundred clean JSON objects in one paste.

Who Can Use Our JSON Unescape
- Backend developers: read an API response that got logged as a stringified blob.
- QA engineers: recover a fixture from a database column that holds a double-serialized payload.
- Site reliability engineers: turn a webhook body in a log line back into the object the service emitted.
- Support engineers: read a customer-shared error payload without hand-stripping the backslashes.
Most reliable way to recover a JSON document from an escaped string
Our JSON Unescape keeps applying the unescape pass until the output stops changing instead of stopping after one layer. A payload that was stringified by a queue and then logged again still comes out as the original object on the first paste.
Deep Layer Handling
Our JSON Unescape walks up to ten layers so a triple-wrapped log line reads as the original object on the first try.
Batch Line Pass
A dump of a hundred escaped database rows comes back as a hundred clean JSON objects without re-running the pass per row.
Stays in Your Browser
A log line with a session token or a customer email never leaves the tab so a recovery never lands in a third-party log.
