How to Use Find and Replace

  1. Paste your text: Enter or paste the content you want to modify into the main text area.
  2. Enter the find term: Type the word, phrase, or pattern you want to find in the "Find" field.
  3. Enter the replacement: Type what you want to replace it with in the "Replace" field. Leave empty to delete occurrences.
  4. Select options: Choose case-sensitive matching, whole word matching, or regular expressions as needed.
  5. Preview (optional): Click "Find All" to see all matches highlighted before replacing.
  6. Replace: Click "Replace All" to make all changes, or "Replace" to change one at a time.
  7. Review results: Check the replacement count and review the modified text.
  8. Copy the result: Copy your edited text to use elsewhere.

Pro Tips

  • Use the preview feature for important documents to avoid unintended replacements.
  • For partial word issues, enable "Match whole word only" option.
  • To delete text, leave the replacement field empty.
  • Always keep a backup of your original text before making bulk replacements.

About Find and Replace

Bulk text editing becomes essential when modifying repeated content across documents, code, or data files. Our Find and Replace tool offers powerful pattern matching from simple text substitution to complex regular expression transformations.

Matching Capabilities

  • Literal Text: Simple search for exact character sequences
  • Case Sensitive: Match exact capitalization or ignore case differences
  • Whole Word: Match only complete words, not partial matches within longer words
  • Regular Expressions: Pattern matching with wildcards, quantifiers, and capture groups
  • Multiline Mode: Handle line breaks within patterns

Regular Expression Power

Regex transforms impossible edits into single operations. Reformat all phone numbers: find "(\d{3})-(\d{4})" replace with "$1.$2". Extract domain from emails: find "@([\w.]+)" capture group $1. Convert date formats: find "(\d{2})/(\d{2})/(\d{4})" replace with "$3-$1-$2". These patterns save hours of manual editing.

Safe Editing Practices

Preview changes before applying to avoid unintended modifications. Overly broad patterns might match unexpected text. We show match counts and highlighting before replacement, letting you verify accuracy. For critical content, work on copies first.

Frequently Asked Questions

What is the difference between simple find and regex find?
Simple find matches exact text: searching "cat" finds only "cat" not "catalog." Regex (regular expressions) uses patterns: "c.t" matches "cat," "cot," "cut." Regex enables complex patterns like finding all email addresses, phone numbers, or words matching specific patterns.
How do I use regular expressions for find and replace?
Common regex patterns: . matches any character, * means zero or more, + means one or more, \d matches digits, \w matches word characters, [abc] matches a, b, or c. Example: "\d{3}-\d{4}" finds phone patterns like "555-1234". Our tool includes a regex reference guide.
Can I do case-insensitive replace?
Yes! Enable case-insensitive mode to match regardless of capitalization: "hello" matches "Hello," "HELLO," "hElLo." You can also preserve original case in replacements - replacing "cat" with "dog" can keep "CAT" → "DOG" and "Cat" → "Dog" automatically.
How do I replace only whole words, not partial matches?
Enable "Whole word" matching to avoid partial matches. This adds word boundaries: searching "cat" won't match "catalog" or "scattered." Without this, you might accidentally change words containing your search term.
Can I preview changes before applying?
Yes! Preview mode shows all matches highlighted before replacing. You can see exactly what will change and selectively approve replacements. This prevents accidental bulk changes - especially important with regex patterns that might match unexpectedly.
How do I replace with captured groups from my search pattern?
In regex, parentheses capture groups. Search "(\d+)-(\d+)" and replace with "$2-$1" to swap numbers: "123-456" becomes "456-123". $1, $2, etc. reference captured groups in order. This enables powerful restructuring of data formats.
