Find & Replace
Type a search term, type a replacement, and watch every match swap out in real time. Flip on regex mode when you need pattern-level precision.

How It Works
1
Load Your Text
Paste an article, code file, CSV, or anything else into the left panel. There is no character cap.
2
Set the Search
Enter the term to find and what to replace it with. Toggle case sensitivity, whole-word, or regex as needed.
3
Grab the Result
The right panel updates live. When it looks right, hit Copy to send the cleaned text to your clipboard.
Best Practices
✅ Do
- Preview the output before copying — the live panel is there for a reason
- Turn on whole-word mode when renaming a variable to avoid mangling substrings
- Use regex sparingly until you confirm the pattern matches what you expect
- Leave the Replace field blank to delete occurrences cleanly
- Check the match counter to verify the right number of hits
- Start with case-insensitive search, then narrow to case-sensitive if needed
❌ Don't
- Run a blind replace on a large document without scanning the preview first
- Forget to escape dots and brackets when searching in normal mode
- Combine whole-word with regex mode — write your own \b boundaries instead
- Assume zero matches means the word is absent — check for hidden whitespace
- Use overly greedy regex patterns (.* without anchors) on multi-line text
- Ignore the red error banner — it tells you exactly what went wrong in the pattern
Tips by Use Case
Text Editing
- Fix a misspelled name across an entire draft in one pass
- Swap British spelling for American (colour to color)
- Remove double spaces by replacing two spaces with one
- Strip trailing whitespace with regex \s+$
Code Refactoring
- Rename a function across a pasted file with whole-word on
- Convert single quotes to double quotes (or vice versa)
- Replace var with const using whole-word to skip "variable"
- Swap console.log calls with an empty string to strip debug lines
Data Cleanup
- Remove commas from numbers: replace , with nothing in digit contexts
- Normalize date separators (/ to -) across a CSV column
- Strip HTML tags with regex <[^>]*>
- Delete blank lines by replacing \n\n+ with a single newline
Content Audit
- Replace an old brand name with the new one site-wide
- Swap outdated product references before republishing
- Locate every URL in a doc with regex https?://\S+
- Count instances of a keyword to check density
Frequently Asked Questions
How do I replace every occurrence at once?
Just type your search term in the Find field and your replacement in the Replace field. The tool applies a global replacement automatically — every match is swapped in the output panel as you type.
What does the "Whole word" checkbox do?
It wraps your search term in word-boundary markers so partial matches are excluded. For example, searching for "cat" with whole-word enabled will not match "category" or "scattered" — only the standalone word "cat".
Can I use regular expressions?
Yes. Enable the "Use regex" toggle and the Find field is treated as a full JavaScript regular expression. You can use character classes like [a-z], quantifiers like +, and groups with parentheses. Back-references in the replacement ($1, $2) work too.
How do I delete text instead of replacing it?
Leave the Replace field empty. Every match will be replaced with nothing, effectively removing those occurrences from the output.
Why does my search return zero matches when I can see the word?
The most common cause is the "Case sensitive" checkbox. If it is enabled, "Hello" will not match "hello". Uncheck it to make the search case-insensitive. Also verify there are no invisible characters or extra whitespace around the target word.
Can I combine regex mode with whole-word matching?
When regex mode is on, the whole-word checkbox is ignored because you can add your own word boundaries (\b) directly in the pattern. This gives you full control over where boundaries apply.
How are special characters like dots or brackets handled?
In normal (non-regex) mode, special characters are escaped automatically so a search for "price ($)" matches that literal string. In regex mode, characters like . * + ? have their regex meaning — escape them with a backslash if you need a literal match.
Is there a size limit on the text I can process?
There is no hard limit. The tool runs entirely in your browser, so performance depends on your device. Texts up to 100,000 characters work smoothly on most modern browsers.
