About the Find and Replace

This find and replace tool edits text in bulk with optional regex, case sensitivity and whole-word matching. A live match count tells you how many replacements will happen before you commit, which is the safeguard a plain editor lacks.

Find and replace in bulk is needed whenever the same correction applies many times: a renamed product across a document, a changed domain in a list of URLs, or a placeholder swapped for a real value throughout a template.

The live match count is the important part. Seeing that a search matches 340 times rather than the 12 you expected is how you catch a pattern that is too broad — before it has rewritten your text rather than after.

Whole-word matching prevents the classic damage of replacing "cat" and finding you have edited "category" and "concatenate" too. Regex handles the cases plain search cannot: matching a pattern of digits, replacing everything between two markers, or capturing part of a match and reusing it in the replacement.

How to use the Find and Replace

  1. Paste your text. Enter the text you want to edit.
  2. Enter find and replace terms. Type what to search for and what to put in its place.
  3. Set the options. Turn on case sensitivity, whole-word matching or regex as needed.
  4. Check the count, then replace. Confirm the match count looks right before applying.

Frequently asked questions

How does this find and replace tool work?

Our tool searches for specific text patterns in your content and replaces them with your specified replacement text. Supports simple text matching, regular expressions for complex patterns, case-sensitive/insensitive options, and can process large text files efficiently.

What is regex find and replace?

Regular expressions (regex) allow complex pattern matching using special characters and quantifiers. Find patterns like email addresses, phone numbers, dates, or custom text patterns and replace them with standardized formats or completely different content.

Can I replace multiple occurrences at once?

Yes! Replace all occurrences of your search term instantly, or use 'Replace First' to only change the first occurrence. The tool shows you how many matches were found and replaced for complete control over the process.

What are common use cases for find and replace?

Content editing (fixing typos, updating terminology), code refactoring (renaming variables, updating imports), data cleaning (standardizing formats), document preparation (updating version numbers, dates), and bulk text processing across multiple documents.

How do I handle special characters in search?

Use regex mode for special characters like newlines (\n), tabs (\t), or escape them with backslashes. The tool provides examples and guidance for handling complex search patterns including whitespace, punctuation, and Unicode characters.

Is there a limit to text size?

The tool efficiently processes large text documents and files. For optimal performance with very large files (>1MB), consider processing in chunks or using specific search patterns to reduce processing time.
