Bulk Find & Replace CSV — free online
You open a CSV and notice the same thing needs fixing in dozens of rows. Maybe an old company name, a typo, a date that changed. Doing it by hand, cell by cell, is slow and easy to get wrong. We added a free tool that does it for you — Bulk Find & Replace CSV — right in your browser.
What it does
You upload a CSV and set up as many find-and-replace rules as you need at once. You can pick which columns each change should touch, so it only edits what you mean. When you're ready, it runs every rule in a single pass and gives you the cleaned-up file.
Nothing leaves your device
The whole thing runs inside your browser. Your file is never uploaded to a server, and nothing is saved or stored anywhere. When you close the tab, it's gone. Even with no internet, it still works.
How to use it
- Open Bulk Find & Replace CSV and upload your CSV.
- Add your find-and-replace rules and choose the columns to apply them to.
- Run it once and download the new CSV.
It's free with no limit. There are more small tools on the Apps page.
