Find and Replace Tool for Text and Regex Matching Online
Find and Replace lets you replace every occurrence of text in an input, with a live preview of the updated result. Use plain-text matching or enable regex to work with patterns and capture groups. Regex flags available are g, i, m, s, and u. Invalid regular-expression patterns display an error, so you can correct the pattern before copying the result.
The Find and Replace tool is a browser-based utility for replacing text without installing a separate program. Use it to find a string in your input and replace all occurrences, then review the result in a live preview. It is useful for quick edits to text, snippets, and other content you can paste or drop into the tool.
Choose plain-text matching for a straightforward string replacement, or toggle regex to use a regular-expression pattern. Regex supports capture groups and the flags g, i, m, s, and u. The result updates live as you work, and an invalid regex pattern displays an error so you can correct it before copying the output.
Plain-text matching searches for the text you provide, while regex lets you describe a search pattern and use capture groups. That flexibility can help when the text you want to change follows a pattern rather than appearing as one identical string. Find and Replace is designed for editing text; it does not convert between file formats.
The tool runs entirely in your browser: your input is processed on your own device and is not uploaded, stored, or sent to a server. It has no server dependency, so after the page has loaded, it continues to work without an internet connection. The tool is free to use.
Developers and DevOps engineers can use it for quick edits to configuration snippets, logs, copied code, or other text. It also suits anyone who needs to make a repeated replacement, inspect the result immediately, and copy the updated text.
Step 1: Paste, enter, or drop the text you want to edit. The tool uses this as the input for your replacement.
Step 2: Enter the text or pattern to find and the replacement text you want to use.
Step 3: Choose plain-text matching or toggle regex to use a regular expression. Regex supports capture groups and the flags g, i, m, s, and u.
Step 4: Review the live preview to check the updated text. If a regex pattern is invalid, the tool displays an error.
Step 5: Copy the result when it looks right.
Use case: Handle a routine Find & Replace task without installing anything locally. Enter the text, make the replacement, and copy the result from your browser.
Use case: Edit text on a machine where you cannot or do not want to install a local utility. The browser-based tool is convenient wherever you can access the page.
Use case: Avoid pasting internal data into a third-party service that sends it to a server. This tool processes your input in the browser.
Use case: Update repeated terms in a block of text, such as changing a project name throughout a copied configuration or document. Replacing all occurrences helps keep the text consistent.
Use case: Use a regex pattern with capture groups when a plain-text search is not specific enough. The live preview helps you inspect the replacement before copying it.
Use case: Apply a text replacement to logs or snippets with regex flags such as i or m. You can review the result as you adjust the pattern.
