Clean, format and deduplicate your Notion databases in one click. Data Cleaner for Notion fixes messy Notion databases in a few clicks: imported CSVs, scraped leads, form responses. WHAT IT DOES - Removes extra spaces (" Jean Dupont " becomes "Jean Dupont") - Capitalizes names properly (marie le gall becomes Marie Le Gall, keeps McDonald, handles de / la / d') - Strips tracking parameters (utm_*, fbclid, gclid...) from URLs - Finds duplicates on the property of your choice (email, name, URL...), with exact or approximate matching that ignores case, accents and spacing - Keeps the most complete row (then the oldest) and archives the others SAFE BY DESIGN - Preview mode: see how many rows will change, with before / after examples, before anything is modified - Optional CSV backup downloaded before any change, with a link to every affected page so you can restore it - Progress bar and a clear report at the end - Everything runs in your browser. No server, no account, no tracking. Your Notion token never leaves your device except to talk to api.notion.com HOW TO START 1. Create an internal integration at notion.so/profile/integrations and copy its token 2. In Notion, share your database with that integration (••• menu > Connections) 3. Paste the token in the extension, pick your database, preview, then clean FREE PLAN The free plan includes 100 modified rows per month. Data Cleaner for Notion is an independent tool.
