About Find and Replace
This tool performs bulk find-and-replace across any amount of text instantly. Unlike your browser's Ctrl+F, this tool replaces every occurrence in one click and gives you the result as clean text ready to copy. It supports plain text matching, case-sensitive matching, whole word matching and full regular expression support.
Available Options
- Case Sensitive — "Hello" and "hello" are treated as different matches when enabled
- Whole Word — only matches the exact word, not words that contain it. "cat" won't match "category"
- Regex — use regular expressions for advanced pattern matching. Find all numbers, emails, URLs etc.
Common Uses
- Replacing an old brand name with a new one across a long document
- Swapping placeholder text like [NAME] with real values
- Deleting all instances of a specific word or phrase
- Normalising different spellings across a document
- Using regex to strip all numbers or email addresses from text
Advanced Find and Replace Techniques
The find and replace tool becomes particularly powerful when combined with its regex mode. For example, you can use find and replace with the pattern \s+ to collapse any run of whitespace into a single space — a faster approach than manually cleaning each gap. Writers standardising spelling across a long document can run multiple find and replace passes in sequence: fix one term, then the next, building up a corrected version pass by pass.
Developers editing configuration files, SQL scripts or log samples rely on find and replace to swap placeholder values, change environment names, or update API endpoint strings across hundreds of lines at once. Because this tool processes text locally in the browser, even large documents complete instantly with no data sent to any server.
Case-Sensitive vs Case-Insensitive Find and Replace
Case sensitivity matters when your text contains a proper noun and a common noun with the same spelling. With Case Sensitive enabled, a find and replace for "Apple" will not touch "apple" or "APPLE" — each is treated as a distinct match. Disable it to catch every capitalisation variant in a single operation, which is useful for cleaning inconsistently capitalised data exported from spreadsheets or database reports. Whole Word mode prevents partial matches — searching for "cat" will not modify "category" or "concatenate".
Frequently Asked Questions
Can I use regex in find and replace?
+Yes. Enable the Regex option to use regular expressions in the Find field. For example, \d+ matches any number, \s+ matches any whitespace, and [aeiou] matches any vowel. All standard JavaScript regex patterns are supported.
Can I replace text with nothing to delete it?
+Yes. Leave the Replace With field empty and click Replace All. Every instance of the search term will be deleted from the text.
How many replacements can it handle?
+There is no limit. The tool replaces all occurrences across any amount of text instantly since everything runs in your browser.
Can I do a case-insensitive replace?
Yes. Toggle the Case Insensitive option to match text regardless of uppercase or lowercase. This is useful when a word appears with varying capitalisation throughout a document.
How many replacements can I make at once?
As many as exist in the text. A single Find and Replace operation replaces all occurrences simultaneously. Run the tool again with different terms to stack multiple replacements.
