Every CRM imports differently
HubSpot matches contacts by email. Pipedrive merges people by name and phone. Salesforce reads dates in your own locale.
This checker reads your file by the import rules of the CRM you pick.
Know what breaks before it lands
An import reports success and leaves fields empty. Rows go missing without a message. Duplicates show up a week later.
Dedupely merges the duplicates any import leaves behind and keeps each merge in Merge History.

No. The check runs in your browser and the file never leaves your computer.
HubSpot, Salesforce, Pipedrive, Zoho CRM, Close, Nimble and Google Contacts. Each one has its own page with its import template.
Emails, phone numbers, dates, numbers, domains and option names. The fixed file keeps every column and leaves empty rows out.
Anything that lives in your account: custom dropdown options, users, pipelines and the records you already have.
