Frequently Asked Questions

How do I find and replace text?

Paste the source text, specify the fragment in the "Find" field, and enter the replacement in the "Replace with" field. The tool shows the result with the replacement applied.

Can all matches be replaced at once?

Yes. By default, the tool replaces all found matches. If you need to replace only the first one, enable the corresponding setting.

Are regular expressions supported?

Yes. In "Regular expression" mode you can use regex patterns and replacement groups such as $1 or $2.

Can I search without case sensitivity?

Yes. When "Match case" is disabled, the search finds matches regardless of uppercase and lowercase letters.

What are Multiline and DotAll?

Multiline changes how ^ and $ behave in multiline text. DotAll lets the dot in a regular expression match line breaks.

What happens if the regex is invalid?

The tool shows a regular expression error message and does not perform replacement until the pattern is fixed.

Can I use the service for logs, HTML, and configs?

Yes. The tool is suitable for bulk replacement in logs, HTML fragments, configurations, lists, documents, and text exports.

Is my data sent to the server?

No. Text is processed locally in your browser and is not sent to the server.

Do I need to register?

No. The tool works immediately and does not require registration.
