Using the
free CSV tools.
Are the RowDesk CSV tools free?
Yes. These focused utilities do not require a paid plan. You can upload, scan and review locally without an account. The first download uses an email gate with optional, unchecked marketing consent.
Does my CSV get uploaded?
CSV parsing, scanning, cleanup, comparison and result generation happen locally in your browser. Raw cell values are not uploaded as part of these workflows. Loading the website and submitting an email involve separate network requests.
Do I need an account?
No account is required for the free tools. An email is requested before the first export, and successful completion is remembered across the four tools for 30 days in your browser. Marketing opt-in is optional.
Which tool should I use?
Start with the Data Quality Checker if you are unsure what needs attention. Use CSV Cleaner for formatting, Duplicate Remover for repeated whole rows, and CSV Compare to find new or matching records between two lists.
What is the difference between the free tools and RowDesk Pro?
The free tools handle focused, one-off tasks. The full RowDesk workspace connects preparation steps. Pro adds advanced duplicate matching, Keep Most Complete, duplicate-group review, comparison in the connected workflow, supporting row exports and change reports. The standalone free comparison tool remains available without Pro.
