How to Use the JSON Unescape Tool

Paste your escaped JSON string into the input field (e.g., a string containing \", \\, or \n).

The tool processes all JSON escape sequences and returns the original, human-readable string.

Copy the unescaped output for inspection, editing, or further processing.

What Is JSON Unescaping?

When a string is stored or transmitted inside a JSON payload, special characters are represented as escape sequences — \" for a double quote, \\ for a backslash, \n for a newline. JSON unescaping reverses this process, converting those sequences back into their literal characters. This is useful when you've received or extracted an escaped string and need to read or work with its original content. It's the direct inverse of JSON escaping.

When to Use This Tool

Inspecting escaped API responses — When a JSON response contains a string-encoded payload (e.g., a nested JSON object stored as a string value).

Debugging double-escaped data — When data has been escaped multiple times and you need to peel back one layer.

Extracting readable content from logs — Log entries often contain JSON-escaped strings that are difficult to read as-is.

Reversing programmatic escaping — When a library or serializer has escaped a string and you need the original value back.

FAQ

Answers about this tool and how your data is handled.

What escape sequences does this tool handle?

All standard JSON escape sequences: \", \\, \/, \n, \r, \t, \b, \f, and Unicode escapes in the form \uXXXX.

Is this the same as JSON parsing?

Not exactly. JSON parsing processes an entire JSON document into a data structure. This tool unescapes a single string value — useful when you've already extracted the string and just need to decode it.

What if the input contains invalid escape sequences?

The tool will flag the error. JSON escape sequences must follow the RFC 8259 spec — sequences like \q are not valid.

Does this tool send my data to a server?

No. It runs entirely in your browser. No data is uploaded.

Can I use this to decode a full JSON object?

If the entire JSON object has been serialized as an escaped string (a common pattern in some APIs), yes — unescaping it will give you back the raw JSON text, which you can then format using the JSON formatter & validator.
