About This Find and Replace Tool
A find and replace tool scans any block of text for a specified word, phrase or pattern and substitutes it with a new value — processing thousands of replacements in under a second. This tool supports plain text matching, case-sensitive search, whole-word boundaries and full regular expressions.
This find and replace tool processes text entirely in your browser, with no server upload and no document size limit. Paste any block of text — an article draft, a code snippet, a data export — enter your search term and replacement value, and apply changes across the entire document in one click. Processes replacements across 100,000+ character documents client-side without delay.
Beyond basic text substitution, the regex engine unlocks pattern-based find and replace operations that static search cannot perform: stripping all HTML tags from scraped content, normalising inconsistent date formats, collapsing irregular whitespace, or extracting and replacing all email addresses in a mailing list. Six built-in regex presets cover the most common text transformation tasks — select any preset to populate the Find field instantly, without writing regex from scratch.
The replace history panel records the last five operations from your current session, showing what was found, what it was replaced with, and how many substitutions were made. Click any history entry to restore those find and replace values instantly — useful when repeating the same transformation across multiple documents in one session.
How to Use Find and Replace
How the Find and Replace Tool Works
- Paste your text into the input area at the top of the tool.
- Enter the word or phrase to find in the Find field.
- Enter the replacement text in the Replace field — leave it blank to delete all matches.
- Toggle Match Case, Whole Word or Use Regex as needed for your search type.
- Click Replace All to substitute every match at once, or Replace Next to step through matches one at a time.
Use our Regex Tester to build and validate your pattern before running it here.
When the Use Regex toggle is active, six preset buttons appear below the options row. Each preset fills the Find field with a tested pattern — Email matches standard email addresses, URL matches http and https links, Phone (India) matches 10-digit mobile numbers starting 6–9, Date matches DD/MM/YYYY format, Extra spaces replaces two or more consecutive whitespace characters with a single space (with the Replace field pre-filled), and HTML tags removes all markup from the input text.
Who Uses Find and Replace
A find and replace tool is a standard component in content, development and data workflows. These are the profiles that rely on it most.
- Developers rename variables, update function names or swap API endpoint strings across code snippets — operations that IDEs handle in files but browsers handle in copied text blocks.
- Writers and editors update character names, standardise terminology or correct repeated spelling errors across long documents without reading every paragraph manually.
- SEO professionals update target keywords, fix anchor text inconsistencies or normalise URL formats across batches of content before publication.
- Data analysts clean exported text datasets — removing HTML tags, collapsing whitespace, standardising date formats — before importing into spreadsheets or databases.
- Support and operations teams redact or anonymise sensitive patterns such as phone numbers or email addresses from text before sharing externally.

Frequently Asked Questions
What is a find and replace tool?
A find and replace tool scans any block of text for a specified word, phrase or pattern and substitutes it with a new value — processing thousands of replacements in under a second. This tool supports plain text matching, case-sensitive search, whole-word boundary matching and full regular expressions (regex), making it suitable for simple edits and complex pattern-based text transformations alike.
How does find and replace work with regex?
When Use Regex is enabled, the search term is interpreted as a regular expression rather than literal text, allowing you to match patterns — all email addresses, all 10-digit phone numbers, all HTML tags — rather than fixed strings. Toggle Use Regex and select from the six built-in presets or enter your own pattern. The tool uses the JavaScript RegExp engine, supporting character classes, quantifiers, lookaheads and backreferences. An invalid pattern is highlighted in red before any replacement runs.
What is the difference between Replace All and Replace Next?
Replace All substitutes every occurrence of the search term simultaneously and shows a count of replacements made. Replace Next substitutes only the first remaining occurrence each time it is clicked — the input is updated after each click, so successive presses walk through remaining matches in sequence. Use Replace Next when you want to review each match individually before committing to a change.
Can I use regular expressions in this find and replace tool?
Yes. Toggle Use Regex to enable full regular expression support in the Find field. Six presets are built in — Email, URL, Phone (India), Date (DD/MM/YYYY), Extra spaces and HTML tags — to get started without writing regex from scratch. For custom patterns, enter any valid JavaScript regex directly. Syntax errors are flagged in red before any replacement is attempted, preventing accidental data corruption.
What does Match Case mean in find and replace?
Match Case makes the search case-sensitive. When enabled, searching for "Cat" will not match "cat" or "CAT" — only the exact capitalisation is matched. When disabled (the default), the search matches regardless of case. Enable Match Case when replacing specific capitalised forms such as proper nouns, acronyms, or programming identifiers where capitalisation carries meaning.
What does Whole Word mean in find and replace?
Whole Word restricts matches to standalone words by adding word boundary anchors. Searching for "cat" with Whole Word enabled will match "cat" but not "catch" or "concatenate". This prevents unintended partial-word replacements in text where a short search term appears embedded inside longer words — a common source of errors when replacing short variable names in code snippets.
Is this find and replace tool free?
Yes. This find and replace tool is entirely free with no account, signup or subscription required. All processing runs client-side in your browser — text is never uploaded to any server. There is no character or document size limit, making it suitable for large documents with 100,000 or more characters.
