Escape or decode a JSON string without sending API payloads, logs, or configuration data to a server.
Maintained by Roshan.
Escape produces string content without surrounding quotes. Unescape accepts that fragment or a complete quoted JSON string.
Automated release checks round-trip quotes, backslashes, line breaks, tabs and Unicode text through escape and unescape. Invalid sequences such as backslash-q are rejected instead of silently changed.

JSON Escape performs the reverse operation when ordinary text or a complete object must travel inside another JSON string. Both operations follow the JSON grammar rather than deleting every backslash blindly: quotation marks, line breaks, tabs, Unicode escapes, and literal backslashes retain their intended meaning, while malformed input is rejected instead of guessed at. The result reports how many escape sequences were processed, the input and output lengths, and whether an unescaped value is itself valid JSON. All parsing and serialization happen in the current browser tab, so private payloads do not need to reach a remote utility service.
Paste {"name":"Mira"} into Escape: the output is {\"name\":\"Mira\"}. Paste that escaped output into Unescape: the result is {"name":"Mira"}, labelled Valid JSON. Compare the name and punctuation before copying it into your application.
Unescape the complete JSON string literal "C:\\Temp" and the result is C:\Temp. The remaining backslash belongs to the path. Deleting it would change the value to C:Temp. A Plain text label is expected for a path; it does not mean decoding failed.
Unescape the complete literal "\"hello\"": the first result is "hello", including its quotes. A second pass produces hello without quotes. Stop after the first pass if your application expects a JSON string literal; continue only if it expects the underlying text.
A service expects a property whose value is a string containing another JSON document. Escape converts the inner object's quotation marks and backslashes while preserving its braces and data, so the result can be inserted into the outer property's quoted value.
A log viewer shows a payload with backslash-quote around every property and backslash-n between lines. Unescape removes that one string layer and marks the decoded result as Valid JSON, ready to paste into JSON Formatter or JSON Diff.
An escaped fragment representing a name and an active flag becomes an ordinary JSON object after one Unescape pass. Quotes become readable again, while intentional backslashes inside paths remain correctly represented instead of being stripped indiscriminately.
An export contains an incomplete sequence such as backslash-u12. The tool reports that it cannot decode the string rather than deleting the slash or manufacturing a replacement character, preserving evidence that the source data is damaged.
Check that you copied the whole value, including any closing quote, and that the source is a JSON string rather than JavaScript source, HTML, or a URL. A complete object such as {"name":"Mira"} is already decoded; use JSON Formatter for it. Return to the original export when a sequence is truncated instead of deleting backslashes until the error disappears.
It escapes double quotes, backslashes, and JSON control characters such as newline, carriage return, tab, backspace, and form feed. Printable Unicode text normally remains readable because JSON supports Unicode directly.
JSON recognizes only a small set of escapes: quotation mark, backslash, slash, b, f, n, r, t, and a four-digit hexadecimal Unicode sequence after u. Other sequences may belong to a programming language or regular-expression syntax, but they are not valid JSON string escapes.
It checks whether the decoded text is valid JSON and reports the result, but it returns the original decoded text rather than reformatting or changing the object. Use JSON Formatter when you want structured indentation or minification afterward.
No. Some backslashes encode quotes or line breaks, while others may be part of a path or another literal value. Unescape parses one valid JSON string layer so meaningful characters are decoded under JSON rules rather than removed blindly.
No. The native JSON string parser and serializer run in browser memory, the page declares no API endpoint, and the result is copied or downloaded directly from the tab.
