Find & Replace

What Is the Find & Replace Tool?

The Find & Replace tool replaces every match of a search string in your text with replacement text. Paste your text, enter what to find, enter what to put in its place, and run it once to update all matches. The result panel also reports how many replacements were made.

The workspace offers three toggles: Case Sensitive, Whole Word Only, and Use Regex. Case Sensitive starts checked. Whole Word Only and Use Regex start unchecked.

How to Use the Find & Replace Tool

1. Open the Find & Replace page.
2. Paste your text into the main textarea.
3. Type the string to find in the Find field.
4. Type the replacement in the Replace With field. Leave it blank to delete every match.
5. Check the toggles: Case Sensitive is checked by default, so uncheck it if you want case-insensitive matching. Leave Whole Word Only and Use Regex off unless you need them.
6. Click Process.
7. Check the replacement count and the updated text in the result panel, then use Copy to copy it or Download to save it.
8. Click Clear to empty the workspace and start over.

Worked Example

Input text: The cat sat. The cat slept.

Find: cat — Replace With: dog — Case Sensitive checked (default), Whole Word Only off, Use Regex off

Observed output: The dog sat. The dog slept.

Observed count: Replaced 2 occurrences

Why: both occurrences of cat were lowercase, so they matched even with Case Sensitive checked, and the rest of the sentences stayed unchanged.

Second check: with Case Sensitive unchecked, input Cat cat CAT, Find cat, Replace With dog produced dog dog dog with 3 replacements. That confirms unchecking Case Sensitive makes matching case-insensitive.

Limitations

• Process replaces all matches at once. There is no Replace Next or replace-one-at-a-time mode, so review the count and output before you copy the result.
• Case Sensitive starts checked. With it checked, CAT will not match cat. Uncheck it for case-insensitive matching. Whole Word Only, when on, limits matches to whole words, so the search string does not match inside a longer word.
• Use Regex changes how the Find field is read: it is treated as a regular expression, not plain text. A pattern with a syntax error will not behave like plain text, so use this mode only when you know regular expressions.
• There is no undo button in the workspace. Keep your original text, or re-run the tool with the Find and Replace values swapped, if you need to reverse a replacement.

How do I delete a word?

Put the word in the Find field and leave Replace With blank, then click Process.
