Search and Replace

Find every occurrence of a word, phrase, or pattern in your text and replace it with something else. Supports case-insensitive matching and optional regular expression patterns.

What Does This Tool Do?

This is the text editor's "Find & Replace" feature — but accessible from any browser without installing anything. You type in what you want to find, type what you want it replaced with, and the tool changes every instance in your text at once. You can choose whether the search is case-sensitive, and you can even use regular expressions (advanced patterns) if you need more powerful matching.

Key Features

🔄

Replace All at Once

Every instance of your search term is replaced simultaneously in a single operation.

🔡

Case-Insensitive Option

Toggle case-sensitivity so "Error", "error", and "ERROR" can all be caught at once.

⚡

Regex Support

Enable regular expression mode for advanced pattern matching beyond simple words.

Before & After

Input and output panels show your original text and the modified version side by side.

How to Use This Tool

Paste your text into the Input box.
Enter the text you want to find in the "Find" field.
Enter the replacement text in the "Replace with" field.
Toggle case-sensitivity or regex mode if needed, then click Replace.

How It Works

The tool searches through your entire text for every occurrence of the word or phrase you entered. When it finds a match, it swaps it out for your replacement text. If you enable regular expressions, the search term is interpreted as a pattern rather than a literal string, allowing for much more flexible matching.

Frequently Asked Questions

Can I use regex patterns?

Yes — enable regex mode to use JavaScript regular expression syntax including wildcards, groups, and lookaheads.

Is the search case-sensitive?

You can toggle case sensitivity. By default it is case-insensitive, so it matches regardless of capitalization.
