Complete Guide: Find and Replace
Everything you need to know about using this tool effectively
The Find and Replace tool searches your text for a word, phrase, or pattern and replaces every match with your replacement string. It supports case-sensitive matching, whole-word matching, and regular expressions. You see the match count before the replacement is applied. All processing happens in the browser.
This tool takes your input text, a search string, and a replacement string. It scans the text for matches based on the options you select and replaces each one. Regular expression mode lets you use patterns like \d+ for numbers or [A-Za-z]+ for words. The result is displayed instantly with a count of how many replacements were made.
Fixing typos across a document
Search for a common misspelling and replace it with the correct form across the entire text at once.
Renaming variables in code
Replace an old variable name with a new one across a code snippet using whole-word mode to avoid partial matches.
Standardizing data formats
Replace date formats, phone number formats, or other patterns in a CSV or data file using regex.
Updating URLs in bulk
Find an old domain name and replace it with a new one across a configuration file or sitemap.
Paste your text
Copy and paste the text you want to modify into the input area.
Enter find and replace strings
Type the text to search for and the text to replace it with.
Set options
Toggle case-sensitive, whole-word, or regex mode as needed.
Preview and apply
Check the match count, then click Replace. Copy the result.
Use whole-word mode when replacing short words to avoid changing parts of longer words.
Regex mode lets you match patterns like dates, numbers, or email addresses.
Check the match count before replacing to confirm you are changing the right number of instances.
To undo, paste the original text back and try a different replacement.
What is whole-word matching?
Whole-word matching ensures the search string is only replaced when it appears as a complete word, not as part of a larger word. For example, searching for 'cat' with whole-word on will not change 'category'.
How do regular expressions work here?
Enable regex mode and enter a pattern in the find field. For example, \d+ matches one or more digits. The replacement field can include backreferences like $1 for captured groups.
Can I undo a replacement?
There is no undo button. Paste the original text back into the input area and run a different replacement, or use Ctrl+Z in your browser.
Is there a text size limit?
There is no hard limit. Very large texts (millions of characters) may slow down on older devices, but typical documents process instantly.
Is my text uploaded to a server?
No. All processing happens in your browser using JavaScript. The text never leaves your device.
