CSV Cleaner — free online tool
You open a spreadsheet export and the CSV is a mess. Extra quotes around everything, stray spaces, fields that won't line up. Cleaning it by hand is slow and easy to get wrong. We added a free tool that does it for you — CSV Cleaner — right in your browser.
What it does
You paste your CSV or upload a .csv file, pick what you want to clean, and download the tidy result. It handles quoted fields properly, so the parts that should stay together stay together. No formulas, no setup — just the cleaned file you can open or share.
Nothing leaves your device
The whole thing runs inside your browser. Your CSV is never uploaded to a server and nothing is saved anywhere. When you close the tab, it's gone. That makes it safe to use even with files you'd rather not send around.
How to use it
- Open CSV Cleaner and paste your CSV or upload a
.csvfile. - Pick what you want to clean.
- Download the tidy result.
It's free with no limit. There are more small tools on the Apps page.
