Contact CSV Close Check.

Include the task you were trying to complete and the error message, if one appeared. A small fictional example is useful. Keep passwords, API keys and real customer records out of support emails.

Current availability

The browser comparison tool is free. Paid subscriptions are not available to the public yet. The private subscription test does not collect real payments.

Free tool data handling

CSV contents are processed in your browser tab and are not uploaded to the application server. Clear the files or close the tab to discard its working data. Reports you download remain on your device.

The application does not add advertising scripts or save your CSV files in browser storage. The hosting provider may process connection and access information and provides aggregate traffic statistics.

Visit pricing, service terms and refunds, privacy details or your account. Once subscribed, use the account billing portal for invoices, payment-method updates and cancellation.

Private hosted tests

The owner-only test explicitly sends synthetic CSV inputs to the server for comparison. It saves summary counts, source fingerprints, timestamps and billing audit information. It does not retain the raw CSV inputs or full exception reports. This is separate from the free browser tool.

Support messages

Messages sent to the support address are handled through Gmail and contain the contact details and information you choose to send. Use the same address for questions about that information or requests to remove it.
