Find and replace across your text, with a case-sensitive option. Runs in the browser.
Find and replace across your text. Runs in the page.
What the find and replace tool does
Paste text, type what to find and what to replace it with, and get the result instantly. A case-sensitive option is included. It is handy for quick edits before pasting into a document.
Frequently asked questions
Does it replace every match?
Yes. Every occurrence is replaced in one pass.
What does match case do?
When ticked, “Cat” will not be replaced by a rule looking for “cat”.
Is anything uploaded?
No. The text stays in the page.
How to use it
- Paste or type your source text into the large input box at the top of the page.
- Enter the exact string you want to locate in the “Find” input field.
- Type the replacement text into the “Replace with” input field, and tick “Match case” if uppercase and lowercase should be treated as different characters.
- Click “Replace all” to apply the substitution across every matching occurrence at once, then click “Copy” to place the result on your clipboard.
Where it comes in handy
A marketing analyst exports a 2,400-row CSV where the vendor name was entered as “Corp.”, “corporation”, and “CORP” across different spreadsheets. Running one find-and-replace pass consolidates all variants before importing into the analytics platform.
A developer cleaning 15,000 lines of SQL code needs to swap the schema prefix from “old_db” to “new_schema”. Using the browser tool avoids opening a separate editor and lets the change propagate across the entire file in seconds.
A researcher processing 800 open-ended survey responses standardizes the date format from “03/14/2023” to “2023-03-14” before running frequency analysis, replacing roughly 620 matched entries in a single operation.
Worth knowing
- The replacement applies to every occurrence in one pass — there is no “replace next” or step-through mode, so you cannot selectively keep some matches.
- Special characters such as parentheses, brackets, asterisks, and plus signs are treated as literal text, not as regular expression operators.
- On very long documents exceeding roughly 50,000 characters, the browser may become temporarily unresponsive while the replacement passes run.
