Paste text with special characters or escaped sequences.

Choose Mode

Select Escape or Unescape mode.

Copy Result

Copy the processed string.

What Is String Escape/Unescape?

The String Escape/Unescape tool converts between literal special characters and their escape sequence representations. In escape mode, newlines become \n, tabs become \t, backslashes become \\, and quotes are escaped. In unescape mode, escape sequences like \n, \t, \\, and \" are converted back to their literal characters. This is useful for working with strings in programming, preparing text for code insertion, or reading escaped string content.

Why Use Our String Escape/Unescape?

Prepare text for embedding in source code strings
Convert escaped sequences back to readable text
Debug strings with invisible special characters
Handle escape sequences in configuration files

Common Use Cases

Programming

Escape text content for insertion into string literals in code.

Debugging

Unescape string values from logs or debugger output.

Configuration

Escape or unescape values in configuration files.

Data Processing

Convert between escaped and literal representations of text.

Technical Guide

The escape function applies a series of string replacements in a specific order. Backslashes are escaped first (to \\) to prevent double-processing. Then newlines (\n), carriage returns (\r), tabs (\t), double quotes (\"), single quotes (\'"), and null bytes (\0) are escaped. The unescape function applies replacements in a different order: literal escape sequences (\n, \r, \t, etc.) are converted to their character equivalents, with backslash escapes (\\) processed last to prevent false matches. This order-dependent processing ensures correct results even with strings containing multiple types of special characters.

Tips & Best Practices

1
Escape mode processes backslashes first to prevent double-escaping
2
Unescape handles standard C-style escape sequences
3
Useful for preparing text to paste into code strings
4
Different from JSON escaping — this does not add surrounding quotes

Frequently Asked Questions

QHow is this different from JSON escape?

This tool escapes general string characters without JSON-specific formatting (no surrounding quotes). JSON escape produces a JSON-valid string value.

QWhich escape sequences are supported?

Standard C-style sequences: \n (newline), \r (carriage return), \t (tab), \\ (backslash), \" (double quote), \' (single quote), \0 (null).

QDoes the order of processing matter?

Yes, backslashes must be processed first in escape mode and last in unescape mode to prevent incorrect conversions.

QCan I escape text for a specific programming language?

The tool uses standard C-style escaping which works for most languages (JavaScript, Python, Java, C, etc.).

QDoes it handle Unicode escape sequences?

Currently it handles standard escape sequences. Unicode escapes (\uXXXX) are not processed.
