How do I find and replace text?

Paste your text or upload a file, enter the text to find and what to replace it with. Replacements happen in real time.

Can I use regex with capture groups?

Yes. Enable Regex mode and use $1, $2… for numbered groups, $ for named groups, $& for the whole match and $$ for a literal $.

Can I replace only the first occurrence?

Yes — change the scope from 'All occurrences' to 'First only' to replace just the first match.

Is the search case-sensitive?

By default the search is case-insensitive. Toggle the case-sensitive option for exact matching.

What file types can I use?

Any text-based file: .txt, .json, .csv, .md, .html, .xml, .yaml. You can also paste text directly.

Everything about find & replace online

Why use an online find & replace tool?

Bulk text replacement is one of the most common editing tasks — renaming variables across code, standardizing formatting in data files, or fixing typos in large documents. Our tool supports plain text and regex replacement with live preview, so you see every change before applying it. No installation, no IDE needed — just paste, replace, and copy.

Common use cases

Replacing variable names or function calls across copied code snippets. Standardizing date formats (MM/DD/YYYY → YYYY-MM-DD) in CSV exports. Fixing repeated typos or formatting inconsistencies in large documents. Converting between naming conventions (camelCase to snake_case). Batch-updating URLs, file paths, or domain names in configuration files. Cleaning whitespace, tabs, or line endings before importing data.

Features & details

Plain text or full regex replacement with capture groups ($1, $<name>, $&). Case-sensitive or case-insensitive matching, all occurrences or the first one only, with the number of replacements shown. The result updates as you type. Supports Unicode and lookahead / lookbehind. A pattern that would backtrack forever is stopped instead of freezing the page. Runs entirely in your browser — no data sent to any server.
