Find and Replace FAQ - Frequently Asked Questions
Is my text uploaded to a server?
▼
No. This tool runs 100% in your browser. Your text is never uploaded anywhere. All find and replace operations happen entirely on your device.
How does the matching work?
▼
By default, the search is case-insensitive and matches plain text. Enable Case Sensitive for exact casing, or Use Regex for pattern matching with regular expressions.
Can I delete text instead of replacing it?
▼
Yes. Type your search term in Find and leave the Replace field empty. Every match will be removed from the output.
What are capture groups?
▼
In regex mode, parentheses create capture groups. Use $1, $2, etc. in the Replace field to reference them. For example, find '(\w+)-(\w+)' and replace with '$2-$1' to swap words around a hyphen.
Why does it say 'Invalid regex'?
▼
Your search term contains invalid regular expression syntax. Check for unmatched parentheses, brackets, or special characters. Disable Use Regex if you want to search for literal text.
Is the search case-sensitive by default?
▼
No. By default, the search is case-insensitive - searching for 'hello' matches 'Hello', 'HELLO', and 'hello'. Check the Case Sensitive box to match exact casing only.
What happens if I refresh the page?
▼
Your text, search term, and replacement are all saved to your browser's local storage. Refreshing restores everything exactly as you left it. Click Clear to remove stored data.
Can I upload a text file?
▼
Yes. Click Upload to select a .txt file, or drag and drop a text file directly onto the text area. The file contents are loaded instantly.
What Is Find and Replace?
Find and Replace is a text transformation tool that searches for a specific word, phrase, or pattern in your text and replaces every occurrence with something else. It works instantly as you type - no need to click a button to see results.
This free online tool supports both plain text search and regular expressions (regex), with optional case sensitivity and capture group replacements. It runs 100% in your browser - no text is sent to any server.
Find and Replace Features
Real-Time Matching
▼
Results update instantly as you type in any field. The match count shows exactly how many occurrences were found, and the result textarea reflects all replacements immediately.
Case Sensitive Mode
▼
By default, matching is case-insensitive - searching for "hello" matches "Hello", "HELLO", and "hello". Enable Case Sensitive to match exact casing only.
Regular Expression Support
▼
Enable Use Regex to treat your search term as a regular expression. This allows powerful pattern matching - for example, \d+ matches any number, and (foo|bar) matches either word. In regex mode, replacement strings support capture groups like $1.
File Upload & Drag and Drop
▼
Upload a .txt file using the Upload button or drag and drop a text file directly onto the text area. The file contents replace the current text in the editor.

| \b\w{5}\b | Exactly 5-letter words | "Hello", "World" |
| (foo|bar) | Either "foo" or "bar" | Alternation group |
| ^.*$ | Entire line (multiline off) | Full line match |
Tips for Find and Replace
Delete matches by leaving Replace empty
To remove all occurrences of a word, type it in Find and leave the Replace field blank. Every match will be deleted from the output.
Use regex for pattern matching
Enable Use Regex to search for patterns like \d+ (numbers), \s+ (whitespace), or custom patterns. Much more powerful than plain text search.
Capture groups in regex mode
In regex mode, use parentheses to capture groups and $1, $2 in the replacement. For example, find (\w+)-(\w+) and replace with $2-$1 to swap words around a hyphen.
Check match count before replacing
The match count shows how many replacements will be made. Verify the count looks right before copying the result to catch unexpected matches.
Case sensitivity matters
Turn on Case Sensitive when you need exact casing - for example, replacing "React" without affecting "react" in prose text.
