Decode Escaped JSON Strings

Working with JSON from logs, APIs, or databases often means dealing with escaped or stringified data. Our decoder handles double-encoded JSON, unescapes special characters like \n and \", and formats the result into readable JSON.

JSON Decoding

Why Use This Tool?

Instant Decoding

Decode and format JSON with a single click. No manual unescape needed.

Smart Parsing

Handles double-encoded JSON, string wrappers, and nested escaped content.

Pretty Output

Results are formatted with proper indentation and syntax highlighting.

100% Private

All decoding happens in your browser. Your data never leaves your device.

How this JSON Decode works

This decoder processes escaped and stringified JSON by removing string wrapping and unescaping special character sequences. The parser handles common scenarios including double-encoded JSON (where JSON strings are themselves JSON-encoded), logs with escaped quotes, and API responses with nested string values that contain serialized JSON.

The decoding algorithm first checks for outer string wrapping (leading and trailing quotes), then systematically processes escape sequences including \n (newline), \t (tab), \\ (backslash), and \" (quote). After unescaping, the tool attempts to parse the result as JSON and formats it with proper indentation and syntax highlighting for improved readability.

The tool handles edge cases like deeply nested escaping where multiple layers of stringification have been applied. Sample buttons demonstrate common input patterns including stringified JSON objects and nested JSON strings. All processing happens entirely in your browser using JavaScript's built-in string and JSON methods, ensuring complete privacy for sensitive data like configuration exports, debug logs, or escaped API responses.

How to Use

{ "key": "value" }

Frequently Asked Questions

What does JSON Decode do?
It unescapes escape sequences (like \n, \", \\) and parses stringified JSON into a readable, formatted structure.
When would I need this?
When you have JSON that's been double-encoded, logged as a string, or contains escaped characters that make it hard to read.
What if my input isn't valid JSON?
The tool will still attempt to unescape common sequences. If the result isn't valid JSON, it will display the unescaped text.
Is my data safe?
Yes, all processing happens locally in your browser. No data is sent to any server.
