IMPORT FILE REPAIR · FREE BETA
Fix the file before the platform rejects it.

FIXERS
One file engine. Different platform rules.
A HubSpot import is not a Klaviyo import. ReadyRows keeps the validation logic separate so each fixer can follow the destination tool’s requirements.

PRIVACY BY DESIGN
Your customer data stays on your device.

FAQ
What ReadyRows is building.
Is ReadyRows only for Klaviyo?
No. Klaviyo was the first fixer. HubSpot is the second, and the architecture is designed for more destination-specific import fixers.
Does ReadyRows upload my customer list?
No. In the current beta, parsing, validation and file generation happen in the browser.
Does it import data into the destination platform?
No. ReadyRows prepares the file. You still upload the output through the destination platform.
Is ReadyRows affiliated with the supported platforms?
No. ReadyRows is an independent utility and is not endorsed by or affiliated with Klaviyo, HubSpot, Salesforce, Mailchimp or their owners.
