Match your file columns with the corresponding ONLYOFFICE™ CRM fields. Please pay your attention to the fact that to import persons correctly you need to have at least one column from your file matched with the 'First Name' field of the ONLYOFFICE™ CRM. The same is for the company import, you will need to match the 'Company Name' field to be able to import a company. The fields containing the dates must have the following format: {0}.
