Prepare contact lists for your next import
For sales teams, agencies and business owners working from spreadsheets, a contact list often needs a review before it enters a CRM. Start by finding repeated rows, removing stray spaces and checking records that share an email address.
The cleaner works with CSV exports from Excel, Google Sheets and other systems. Review its preview and download the result before deciding where to import it.
Free to use, with a separate CRM next step
You do not need a NoClutterCRM account to clean or download your CSV. The contact cleaner processes your file in your browser tab and never adds contacts to a workspace automatically.
When you need an ongoing home for contacts and conversations, explore contact management in NoClutterCRM. Importing a reviewed file is a separate, authenticated step.
