Unescape JSON strings online with instant formatting.
Unescape stringified JSON from logs, database records, and cache entries. Restore clean, parseable JSON with zero server uploads and 100% private in-browser parsing.
JSONGlow's JSON Unescape utility is a free, 100% private in-browser tool that removes escape backslashes and quotes from stringified JSON payloads, restoring clean, parseable JSON.
Overview
Why unescaping JSON logs and records is crucial for debugging
Developers frequently encounter stringified JSON inside database columns, Kafka event streams, Redis cache entries, AWS CloudWatch logs, and webhook notification payloads where an entire JSON object has been encoded as an escaped string literal with '\"' and '\n'.
Attempting to read or debug double-escaped JSON by eye is frustrating. Manually removing backslashes easily introduces syntax errors such as broken quotes or misplaced delimiters. An automated unescaper parses out string encoding and restores valid, readable JSON structures instantly. Once unescaped, you can beautify the output with our JSON Formatter or validate strict syntax using the JSON Validator.
Unlike cloud conversion websites that upload your application logs and database exports to external servers, JSONGlow runs 100% locally in your web browser sandbox. Your proprietary payloads and credentials remain strictly confidential on your machine.
You can copy unescaped JSON with one click, download it as a .json file, format with customizable indentation, or switch back to escape mode anytime using our integrated toolbar. If you need to encode clean JSON for code variables, switch to our JSON Escape Tool or auto-fix trailing commas and syntax defects with JSON Repair.
Workflow Guide
How to unescape JSON strings in 3 steps
Input your escaped string
Paste stringified JSON containing '\"' or '\n' into the editor panel.
Instant client-side unescaping
The tool immediately strips backslashes and parses the string back into standard JSON format.
Export clean JSON
Click 'Copy' to paste into your editor or open in JSON Formatter for deep tree inspection.

}Troubleshooting & Edge Cases
Common JSON unescaping pitfalls & solutions
Outer enclosing quotes left unhandled
Why it happens: Some logs format stringified JSON with outer wrapping quotes ("{\"a\": 1}").
Multiple levels of escaping (triple backslashes)
Why it happens: When JSON is serialized multiple times through nested queues or proxies, backslashes multiply (\\\"key\\\").
Broken unicode escape sequences (\uXXXX)
Why it happens: Truncated or corrupted unicode sequences can prevent valid string unescaping.

Frequently Asked Questions
Common questions answered.
Need more help? Our tools execute entirely in your browser without transmitting any payload to remote servers.
What causes JSON to become escaped like this?+
When a backend service serializes an object that already contains a stringified JSON property, or when a logging library converts a structured payload into a string before storing it in ElasticSearch or CloudWatch, quotes are escaped with backslashes (\"key\").
Does JSONGlow upload my unescaped data to any server?+
Never. All unescaping and parsing execute entirely in your local browser sandbox. No payload content is transmitted over the network.
Can this tool unescape multiline strings?+
Yes. Escaped newline characters (\n) and tabs (\t) are accurately converted into real line breaks and indentation.
How can I format the unescaped JSON after cleaning it?+
Copy the unescaped result and open our dedicated JSON Formatter, or use JSON Repair if the payload contains syntax defects.
What if my string is double-escaped with multiple backslashes?+
If your JSON was serialized multiple times, you can unescape the first layer, copy the output back into the input, and unescape again.
Is there any usage limit or file size cap?+
No. The tool is 100% free with no account signup, usage limits, or paywalls.
