How to Use the Tool

Enter Input Text: Paste or type your text in the input field, or upload a file using the file upload button.
Enter Find Text: Type the text you want to find in the "Find Text" field.
Enter Replace Text: Type the replacement text in the "Replace With" field.
Configure Options (Optional):
- Case Sensitive: Check to match exact case (e.g., "Hello" won't match "hello")
- Use Regular Expression: Enable regex pattern matching for advanced searches
- Whole Words Only: Only replace complete words, not parts of words
View Results: The replaced text appears automatically in the output panel with statistics showing the number of matches and replacements.
Copy or Download: Use the copy button to copy the result, or download it as a file.

Replacement Options

Case Sensitive: When enabled, the search is case-sensitive. "Hello" will only match "Hello", not "hello" or "HELLO".
Regular Expression: When enabled, you can use regex patterns for advanced matching. For example, \d+ matches any sequence of digits.
Whole Words Only: When enabled, only complete words are replaced. For example, replacing "cat" won't replace "category" or "scatter".

Regular Expression Examples

When "Use Regular Expression" is enabled, you can use powerful pattern matching:

\d+: Matches one or more digits (e.g., "123", "4567")
\w+: Matches one or more word characters (letters, digits, underscore)
^: Matches the start of a line
$: Matches the end of a line
.: Matches any single character
.*: Matches any sequence of characters
[0-9]: Matches any single digit
(group): Captures a group for use in replacement (use $1, $2, etc. in replacement)

Example

Input Text:

Hello world! This is a sample text. Hello again!

Find: Hello

Output:

Hi world! This is a sample text. Hi again!

Frequently Asked Questions

How does the text replacement work?

The tool searches for the specified "Find Text" in your input and replaces all occurrences with the "Replace With" text. You can configure options like case sensitivity, regex support, and whole word matching to control how replacements are made.

What is a regular expression?

A regular expression (regex) is a pattern that describes a set of strings. It allows you to match complex patterns rather than exact text. For example, \d+ matches any sequence of digits. Enable "Use Regular Expression" to use regex patterns in your search.

Can I replace multiple different texts at once?

The tool replaces one pattern at a time. To replace multiple different texts, perform the replacements sequentially - replace the first pattern, then use the output as input for the next replacement, and so on.

What happens if I use an invalid regular expression?

If you enter an invalid regular expression, the tool will display an error message and keep the original text unchanged. Make sure your regex pattern is valid before using it.

Can I undo a replacement?

The original input text remains in the left panel, so you can always see what was changed. If you need to undo, simply modify the find/replace fields or clear and start over. The tool doesn't modify your original input.

Can I upload files for replacement?

Yes! You can upload text files using the file upload button in the input panel. The tool will load the file content, and you can then perform replacements and download the result.

Is my data safe?

Yes, all text processing happens locally in your browser. Your text is never sent to any server, ensuring complete privacy and security. You can safely process sensitive or confidential documents.
