Pro tip
Turn on Review each match when you're not 100% sure every instance should be replaced — like changing a name that might also appear in a different context. You approve or skip each one individually.
Common uses
Code & config
Update variable names, DB credentials, or API URLs across large files safely.
Content cleanup
Fix common typos, swap brand names, or standardize formatting before publishing.
Mail merge prep
Find placeholders like [NAME] or {{COMPANY}} and swap them with real data.
Data cleanup
Strip out unwanted characters from CSVs or logs using standard replacements or regex.
Option guide
Case sensitive
Ensures exact case matches. Searching for "Apple" won't affect "apple".
Whole word only
Stops partial matches inside longer words. "cat" won't match "catalog".
Regex
Use regular expressions to match flexible patterns like digits (\d) or wildcards (.*).
Support & FAQ
How it works
1
Add your text
Paste text directly into the box, or upload a .txt file from your computer. Nothing is sent to a server — it all stays in your browser.
2
Set up your find & replace rules
Type what you want to find and what to replace it with. Add as many pairs as you need — they'll all run in one pass.
3
Choose your matching options
Turn on case sensitivity, whole-word matching, or regex if you need more precise control over what counts as a match.
4
Replace all, or review one by one
Click "Replace all" for an instant result, or turn on "Review each match" to approve or skip every occurrence individually.
5
Copy or download your result
Copy the cleaned-up text to your clipboard or download it as a .txt file — whichever's easier for what you're doing next.
Common questions
Is my text uploaded to a server?
No — everything runs in your browser. Your text never leaves your device, whether you paste it in or upload a file.
Can I do more than one find & replace at once?
Yes — click "Add another find & replace pair" to queue up as many rules as you need. They all run together in a single pass over your text.
What does "Whole word only" actually do?
It stops partial matches inside longer words. Searching for "cat" with this on will match "cat" but skip "category" or "concatenate."
Do you support regular expressions (regex)?
Yes — turn on "Use regex" and your Find field will be treated as a regex pattern, letting you match things like digits, repeated characters, or flexible patterns instead of exact text.
What does "Review each match" do?
Instead of replacing every match automatically, it highlights each occurrence one at a time so you can choose to replace it, skip it, or replace all remaining matches at once.
What file types can I upload?
Plain text-based files — .txt, .csv, .md, .json, .html, .xml, and .log all work. The tool reads the file as text either way.
I left "Replace with" blank — why does the text look the same?
Leaving it blank deletes the matched text, which is correct — but it can leave a double space behind where the word used to be, making the change hard to spot at a glance. Turn on "Clean up extra spaces" (on by default) to automatically tidy those gaps after replacing.
