Input (Stringified JSON)

Output (JSON)
What It Does
Convert double-stringified or escaped JSON back to proper JSON format. This tool handles JSON that has been stringified multiple times, removing extra escape characters and quotes to produce valid, parseable JSON data.
Common Use Cases
- Fixing JSON that was accidentally stringified twice
- Cleaning up JSON from console.log outputs
- Restoring JSON from string literals in code
- Processing JSON extracted from database string fields
- Debugging API responses with over-escaped JSON
How to Use
- Paste the stringified JSON into the input
- The tool parses and restores proper JSON format
- View the clean JSON output
- Copy the valid JSON for use in your application
Features
- Handles multiple levels of stringification
- Properly unescapes special characters
- Validates output as proper JSON
- Preserves all original data
Examples
Below is a representative input and output so you can see the transformation clearly.
"{\"name\":\"Ada\",\"score\":9}"{
"name": "Ada",
"score": 9
}Edge Cases
- Very large inputs may take a few seconds to process in the browser. If performance slows, split the input into smaller batches.
- Mixed formatting (tabs, line breaks, or inconsistent delimiters) can affect output. Normalize spacing first if needed.
- Unstringify JSON follows the selected options strictly. If the output looks unexpected, re-check option settings and input format.
Troubleshooting
- Output looks unchanged: confirm the input contains the pattern this tool modifies and that the correct options are selected.
- Unexpected characters: check for hidden whitespace or encoding issues in the input and try normalizing first.
- Slow processing: reduce input size or try a modern browser with more available memory.
Tips
If your JSON has backslashes before quotes like \", it's been stringified and needs this tool to restore it.
Frequently Asked Questions

No. This tool is designed to run in your browser, and we do not store or log your content during processing.
Is conversion instant?
Yes for most inputs. Output updates immediately, and large inputs may take a moment depending on your device.
Can this handle large text?
It can handle large text, but performance depends on your browser and device. For very large files, consider splitting the input.
Does it support mobile?
Yes. The interface is responsive and works on phones and tablets, so you can use it on the go.
Can I use it for commercial projects?
Yes. You are free to use the output in personal or commercial projects without attribution.
Does this affect numbers or punctuation?
Only if the selected options target them. Otherwise, numbers and punctuation are preserved as-is.
