Overview
Introduction
Wrapping text in quotes for use in code or a config file is trivial until the text itself contains a quote character.
This tool handles the escaping for you.
What Is String Quoter?
A quoting tool that wraps input in double quotes and escapes anything inside that would otherwise break the literal, via JSON.stringify().
It runs entirely client-side as part of this site's String Tools collection, so nothing you paste is ever uploaded to a server.
How String Quoter Works
The tool calls JSON.stringify() directly on the input text, which both escapes special characters and adds the surrounding double quotes in one step.
The transformation happens synchronously in JavaScript the moment you type, with no network round trip involved.
When To Use String Quoter
Use it when you need a ready-to-paste quoted string literal for code, JSON, or a config file.
It's also useful for safely quoting arbitrary user-supplied text.
Often used alongside String Unquoter and JSON String Encoder.
Features
Advantages
- Escaping is spec-correct since it reuses JSON.stringify().
- One step instead of manually adding quotes and escaping separately.
Limitations
- Always produces double-quoted output; single-quote conventions need separate handling.
- The result is JSON/JS-flavored escaping, which may differ slightly from other languages.
Examples
Best Practices & Notes
Best Practices
- Use Unquote a String to reverse this and confirm round-trip correctness.
- For non-JSON-flavored languages, double-check escaping conventions before relying on this output verbatim.
Developer Notes
This is a direct pass-through to JSON.stringify(input), reusing the same escaping logic as the JSON category's tools rather than reimplementing quote-escaping rules.
String Quoter Use Cases
- Producing a ready-to-paste quoted string literal
- Safely quoting arbitrary text for a config file
- Preparing a value for a JSON field
Common Mistakes
- Expecting single-quoted output.
- Quoting already-quoted text and getting doubled outer quotes.
Tips
- Pair with Unquote a String to verify the operation is reversible for your text.
