What is String to JSON Converter?
Got JSON that's stuck as a string? We've all been there – escaped strings, stringified JSON, or text that needs to become actual JSON. This tool converts all that string data into proper JSON (JavaScript Object Notation) format.
As MDN Web Docs explains, JSON strings often need parsing to become usable objects. Our converter handles escaped strings, stringified JSON (you know, that JSON.stringify output), and text data, turning them all into valid JSON. We follow the RFC 8259 JSON specification, so everything's standard.
Everything happens in your browser – your strings never leave your computer. Convert them to JSON instantly and use them in your apps.
What Makes This Tool Different
String Parsing
We take your string data and turn it into valid JSON. Handles escaped strings, stringified JSON, and plain text automatically.
Escape Handling
We properly handle all those escaped characters and convert them to valid JSON. Unescapes everything while keeping the structure intact.
Formatting Options
Outputs nicely formatted JSON with proper indentation. Or minify it if you want compact output – your choice.
File Upload Support
Got a big file? Just upload it. Works great for those massive string files or escaped JSON documents.
Copy & Download
One click to copy, or download it as a file. Drop it right into your app – it's ready to go.
Syntax Highlighting
Provides beautiful syntax highlighting for both input strings and output JSON. Makes it easy to verify the conversion.
How It Works
Paste or Upload String
Paste your string data into the left editor, or click "Upload" to load a file. You can also click "Sample" to see an example. The string can be escaped JSON, stringified JSON, or text data.
Automatic Conversion
The tool automatically converts your string into valid JSON format. Escaped characters are unescaped, and the string is parsed into JSON structure.
Copy or Download
Review the converted JSON in the output panel. Click "Copy" to copy it to your clipboard, "Minify" to compress it, or "Download" to save it as a file.
When You'd Actually Use This
API Development
Convert stringified JSON from API responses back into JSON objects. Essential when APIs return JSON as strings instead of objects.
Database Queries
Convert string data from databases into JSON format. Perfect for working with text columns that contain JSON data.
Escaped Strings
Unescape JSON strings that have been escaped. Converts escaped characters back to proper JSON format for use in applications.
Data Processing
Process string data into JSON format for further manipulation. Essential step in data pipelines and ETL processes.
Common Questions
Is my string data stored?
No. String conversion happens entirely in your browser using JavaScript. Your data never leaves your computer.
What types of strings can it convert?
The tool converts escaped JSON strings, stringified JSON (JSON.stringify output), and text data that can be parsed as JSON into valid JSON format.
Does it handle escaped characters?
Yes. The converter properly unescapes characters like \n, \t, \", and others, converting them to valid JSON format.
What if the string isn't valid JSON?
If the string cannot be converted to valid JSON, you'll see an error message. The tool attempts to parse and convert, but some strings may require manual editing first.
Can I minify the output?
Yes. Click the "Minify" button to compress the JSON output. Useful for reducing file size or for use in production environments.
What's the difference from JSON Parser?
JSON Parser works with already-valid JSON. String to JSON Converter handles string data that needs to be converted to JSON format first, like escaped strings or stringified JSON.
Other JSON Tools You Might Need
String conversion is just one JSON task. Here are other tools that work well together:
