Why does it use JSON's escaping rules?

JSON's string escaping is a well-specified, widely understood subset of the escaping most C-family languages already use, so the result is valid as both a JSON string and a string literal in JavaScript and similar languages.

What if my text already starts and ends with quotes?

They're treated as ordinary characters and escaped like any other embedded quote, then the whole result is wrapped in a fresh outer pair, so you'd end up with escaped inner quotes inside new outer ones.

Are newlines and tabs escaped as well?

Yes. Control characters are converted to their escape sequences, so a tab becomes \t and a line break becomes \n. That is precisely what lets multi-line text collapse into a single valid string literal.

String Quoter Online - Wrap Text in Quotes

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.
Adds the quotes and performs the escaping in one operation, so there is no intermediate state where the text is quoted but not yet escaped.

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

Quoting text with an embedded quote

Input

She said "hi"

Output

"She said \"hi\""

The embedded double quote is escaped and the whole string is wrapped in a fresh pair of quotes.

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.
Quote once, at the point of embedding, since running an already-quoted string through again nests the escaping another level deeper.

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.
The output is valid in JavaScript, JSON, and most C-family languages, because they share the same core escape sequences.
