How does it work?

This tool swaps all occurrences of specified characters or selections (substrings) in your text. You can choose between two modes:

Swap Characters: Replaces individual characters with each other.
Swap Selections: Replaces longer text selections (substrings) with each other.

Examples

Swapping Characters

Original text:

Hello, World! This is a test string with some letters.
The letters 'e' and 'o' appear multiple times in this text.

After swapping 'e' and 'o':

Holle, Werld! This is a tost string with semo lottors.
Tho lottors 'o' and 'e' appoar multiplo timos in this toxt.

Swapping Selections

Original text:

The quick brown fox jumps over the lazy dog.
The lazy dog watches the quick brown fox.
A fox is quick and brown, while a dog is lazy.

After swapping "fox" and "dog":

The quick brown dog jumps over the lazy fox.
The lazy fox watches the quick brown dog.
A dog is quick and brown, while a fox is lazy.

This tool is useful for:

Quickly replacing characters throughout a document
Creating cipher text by swapping letters
Fixing consistent typos or character errors
Swapping terms or phrases in text
Creating variations of text for testing

Options:

Swap mode: Choose between swapping individual characters or longer text selections.
First character/selection: The character or text to be replaced by the second one.
Second character/selection: The character or text to be replaced by the first one.
Case sensitive matching: When enabled, uppercase and lowercase letters are treated as different. When disabled, they are considered the same (but the original case of each occurrence is preserved in the result).

Note:

In "Swap Characters" mode, you can enter multiple characters, but the tool will treat them as individual characters to swap. If you want to swap longer text segments, use "Swap Selections" mode instead.
